Customer Ratings & Reviews

good stuff

I got this free when i ordered my 4x6 speakers i installed it on the rear set no space in the front openings so far so good still sticking to the metal and no rattles.

Nice Wiring Kit

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

Works pretty good

I bought this product for my trucks doors, and I noticed it's thicker than other sound dampening material I've used before that I paid a lot more for. This is a great product at a great price

Easy to use, good performance!

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

EXCELLENT

Very nice sound dampening material easy to install and gives a great added depth to the sound of yr system, deeper bass and mids and also minimizes the resonance of the factory locations

HIGH QUALITY

EASY TO CUT TO THE SIZE YOU NEED, DOES A GREAT JOB AT MINIMIZING VIBRATIONS

ok speaker exagerated highs

I like a flat response in speakers for realistic sound. I record music and reference the mix in my car also. The high boost makes it hard to judge a mix. might be good for some people but just too bright in one high frequency for me.

sound deadener

Amazing stuff I wish I could afford to cover my whole truck with it!

Sastifying Product

I got the Polk Audio db651 6.5 in speakers. I have a Dodge Dakota Extended Cab and got 2 pairs. I am VERY impressed with the sound clarity and just sheer power of these speakers. Granted it is in a truck cab but these things are extremely loud. They have great clarity at all volume levels and are able to play loud enough to make me yell at my passengers to be heard and they still didn't have any distortion. For $65 a pair they are a steal. I'm only running 22 rms thru my head unit and they can take 60 rms I believe. I highly recommend these speakers to anyone.

Great Buy when 50% off

Now this product is good quality! I highly recommend this product!

Nvx = quality at the best price.

I'm so happy with all my NVX products. They are always the best in quality and price. No smell and if it's not a lot you can apply it without a roller. (I used my hands and the back of a screw driver to really smooth it out)

Does the job great

I would definitely. Recommend this it was part of a promotional. Thing used alot of other brands would say works just as well if not better glad i did the deal . Now i can get more for cheaper. "Get it you wont be disappointed "

kind of tinny sounding

There seems to be one high frequency that is much louder than the rest around the frequency of a hi hat or cymbal. I prefer a flat response.
These speakers have that high boost which colors the sound and doesn't sound real.

Polk Audio db651

I had replaced the Polk Audio db61 door speakers from some kenwood speakers that I ended up blowing. Believe it or not, they sound better!
And for the price you cant beat it anywhere.

Excellent value and sound

Very nice sounding speaker for a low budget co ax!

Awesome product

These Polk speakers are great! I use them in my ice chest radios with no issues whatsoever. I will definetly be purchasing more!!

GREAT

These speakers were installed in a 20 ft wakeboarding boat and without an amplifier these speakers get loud and clear with no distortion.

Major step up from stock boat speakers

Like others speaker clarity and loudness are great, bass is a little weak. I'm working on a set for my Tundra next.

BETTER THAN DYNAMAT AT A BETTER PRICE!

BETTER THAN DYNAMAT AT A BETTER PRICE!
Very sticky backing and very easy to install.
The NXV product line offers top notch performance with awesome value that can't be beat for the price.
I am speaking from 27 years of car audio experience.
LOOK NO FURTHER YOU HAVE FOUND WHAT YOU NEED...NVX !

Great for the price

Polk has always been a good brand. With a well adjusted stereo I can get good bass and treble as a two-way speaker is expected. The mids are alright as expected.

Four of these in my truck can provide enough thump to delay my decision on installing a sub. Everything from acoustical, rock, r&b, and whatever sound good. This is coming from an audiophile.

NVX

I would recommend the NVX dampening sheet..because it's the best one on the market

Incredible speakers (especially for the price)

Great speakers for an even better price. Very well built and sound phenomenal. Offer great highs, good mid, and surprising bass. They shake my truck even when they are barely cranked. I have a 98 GMC Sonoma with a JVC head unit running 18 watts RMS power and the speakers have plenty of power.

My only complaint is that installing the speakers was very difficult. The supplied mounting bracket was nowhere close to the right size for my truck so I had to re-drill mounts and use those horribly tiny mounting brackets they send you. The speakers are also much taller than stock and push on the door panels slightly. Grill did not even begin to fit.

Overall, though, I would recommend these speakers for anything from a stock head unit to a powerful aftermarket head with an amp. They are a major upgrade I should have done years ago. I plan on putting these speakers in every future car I own.

Great!

Nice thick and easy to install. Improved sound and road noise!

sound deadner

first time using deadner but it was easy to use and it made a noticeable difference in the sound I would recommend

Thick

it thick and sticky and works good but I recommend you get a roller and clean the area you are applying to

Reduce Distortion

These are great. Installed them on my door panels behind the speakers. They help to greatly reduce any resonance and vibrations caused my road noise and sound waves. Helps speakers sound better and increase sound quality they can produce.

A++

Don't go to "Worst Buy" and pay way too much for the same thing. NVX is a solid product and does the job very well for the money.

Great stuff

This stuff is great! I got it free with my Skar speakers and it worked just like they say. I can crank it up and get almost no rattles where before I had all kinds of rattles. It's also very easy to put on and trim.

Quiet the doors

Worked perfectly to silence door rattle and even got rid of some road noise.

Serving It's Purpose

This sound deadner came with some jbl p660c speaker and i had them installed when speakers were. These are installed inside front door on the inside of door skin and i have no rattles on the door skin. I guess it's doing it's job. No complaints about it.

Great sound dampener at agreat price .

I bought this from sonic to mount my NVX VSP65 speakers In the front and rear of my car and let me tell you there is not even a hint of vibration even when cranked ! A must have for speaker installation . Another fantastic product from Sonic and NVX with fast professional service !! Two thumbs up .

Shop around!

For the price, there are better sound dampening products available.

Good sound deadening material

This stuff is pretty good at keeping the sound in and other noises out. very thick, no smell. Great product, easy to cut.

good stuff

I used this stuff on the half doors of my ext. cab to help in prove sound and it works. its good stuff but for what it is its over priced in my opinion but worth the cast.

Quality stuff

This stuff is very easy to use, just make sure the surface area is clean first, preferably with a mild grease detergent like dish washing liquid. The sheets are definitely thick and can become quite sticky, so plan ahead properly. Best to do it on a hot day where the panels are already nice and hot. Can't say if it made a difference as I changed the entire stereo and deadened the car at the same time.

this stuff was truly a lifesaver

I had no idea I needed this until I ordered it. I used it for waterproofing a custom made compartment so that I can get an amp in the dash of a corvette. can't recommend this stuff enough.

great product...

This stuff is pretty good at keeping the sound in and other noises out. no smell. Great product.

Great Speakers

When my factory radio, cd player died I decided to update my car stereo and purchased a new cd player with bluetooth. I also purchased a new set of speakers the Polk Audio db651. I have polk Audio speakers on my home stereo and that is why I selected these. I am very happy with the purchase. The sound is crisp and clear great for listening to Jazz and all types of music.

awsome

Bought this speakers 8 months ago and all I could say is wow!! Sound is crystal clear! Big difference from stock speakers. Paired this with a cde-102 a ktp-445 and a sub. You have to hook this to an amp to really appreciate this speakers!

Great Value!

I ordered this product to replace some stock speakers in my 2004 Tahoe. For some reason, I thought the the speakers would fit right in, but I needed an amp to connect them to. That was a mistake on my part. After having the speakers professionally installed, along with some extras to replace all the speakers in the Tahoe, I am glad the situation played out the way it did. I love the sound quality and everything works perfect with the Polk Audio 12" subwoofers that were installed years ago.

Good value

For what you pay this is a good value, it dampens the vibration caused from the aftermarket speakers, and also reduces road noise depending on locations.

Great buy!

Perfect SQ and fit perfect in the Dodge Dakota. Bass sounds better in these too!

amazing

I ordered these speakers last week and they came in, in 3 days. They were super easy to install. these speakers are amazing. I have heard other more expensive speakers and these beat them by far. The bass, mid, and treble is crystal clear. I highly recommend these to anyone who is interested.

Great value

Great replacement for factory speakers. The sensitivity and response of these speakers with the factory headunit was great.

great deal

These polk speakers sound amazing for such a small size. I can't wait to get the other set installed. Sonic Electronics has the best price out there, and delivery was super fast.
Thank You Sonic

awsome sound

got these today installed them great mids and highs running them off an old xm503 amp with 2 4x6 db651 and 2 8" kicker subs on a mtx amp this combo rocks

Loud and clean

Bought 2 sets for my sons ski boat, he had clarion prior to these. He has them amped at 80 watts and they sound great. Service from Sonic was fantastic, very fast and exactly what they said.

Super value for the money.

I have had Polk audio speakers before so I figured I buy this pair for my CRV. I was looking at speakers that were at least three times the cost and almost bought them but the car is older and didn't want to spend too much on them. I have been amazed at how good these speakers sound. They have plenty of base and good treble and mid-range. These speakers are crystal clear. I highly recommend them.

crystal clear speakers!!

These speakers sound great. but they could definatly use a amplifier dont get me wrong they sound perfectly fine off the headunit but to make em shine get a amp.. good price for a quality speaker!!

Great speakers, great price

Ordered a pair of these 2 years ago to replace blown OEMs in the front. The rear OEMs finally gave out so I'm buying another pair. Quality and ease of install added to great sound from a well-known company made this a complete no-brainer. Sonic Electronix was great then (price and service) so, of course, I came back. Next, a new head unit.

Love my polk

I got this set about 5 or so months ago. I really like mine, works perfect with my system. Real clear over the bass. I also have the polk component set and love them. Also works really good with loud systems.

love them

in the top 5 for sum of the best coaxials i have had and at under $75. these are THE BEST your going to find i have a old school v12 75x4 on them and are keeping up with my rf T2d212

polk db651

I have used these speakers with and without an amp. They sound much better with than without. I think polk makes an excellent product and I would recommend them to anyone.

Polk Audio db651

I really likes these speakers, I put them in a golf cart, speakers were exposed to the elements and held up fine. Sounded great and looked great!

All round good speakers

One thing to note is that the DB651s do not come with mounting brackets as they are the slim version. With the DB651 however, they are included in the box. Overall the speakers are great. It's definitely not a very 'bassy' speaker, I would more compare it more towards a set of studio monitors, providing clear/clean sound.

Good sound & great value

Installed 6 months ago to replace the oem crappy front speakers on 2011 Hyundai Tucson Ltd. Sound quality improved a lot. Easy good fit installation with the accessories provided, but the simple manual does not help. The good looking grill covers cannot be used which is a waste. I got a good deal/bargin from Sonic, cheaper than I buy locally in Canada even with all the shipping, handling costs.
In addition, I feel the Polk Audio db651 sounds even better than the Infinity ref 6032si I installed in the rear doors.
Highly recommended at this price range.

best thing money can buy!

i have these speakers in my 07 impala with the polk audio 6x9s,first off polk audio dont bs. i had both pair playn off my factory radio with factory tweets and man my car sounded just lik my sudio room but not as loud .then i also added 2 pairs of kicker 1/2 inch tweets a pair in the factory spot in front and a pair on the back panels with a kicker 350.4 amp powering all 8 speakers now my car sounds like a concert. this mix is the best i promise.everybody at my school including my teachers and principal. i paid around $800 for this set up and im not stressing about it. this web site is killn the store prices if u can aforde my set up do it. 100% positive your getn the feed back u want everywere u go!

great speakers

Good sound, looks and value. Nothing less then what i would expect from polk.

Polk 651

These are a nice upgrade from the one-way speakers that were in the sound bar in my '08 Jeep. They fill out the spectrum well and, with a sub-woofer, you get a nice, full range. Excellent bang for your buck. The adapter ring (included) is needed so be prepared for a little drilling.

Great Value,SOUNDS PERFECT!

Was a direct fit for my 93 GMC Safari van,front dash speakers.No modifications or altering needed at all.

Great Deal

Good clear speakers can take alot of power good mids also!!!

Very nice coaxial for the price

Great coaxial, for the price. Good sound. Plays much cleaner than the factory speakers that I replaced. Not as much bass, however, so you'll probably want a subwoofer.

Vibration mat

This mat works great on my doors and it is a great value.

Bad A** Speakers

I am a big fan of Sonic Electronix. I will always purchase my car audio from them. That being said. These speakers are very nice. I put them in my 02 Dakota and for only being 6 1/2s they really are very full sounding. I highly recommend these speakers and Sonic Electronix.

Sound Great

My buddy heard my Polk Mobile Monitor separates and wanted me to put some speakers in his truck. I put these in the doors and the matching 4 x 6s in the dash. While I was putting away my tools, I could hear him cranking his radio. I looked into the truck and he was grinning from ear to ear. I told him they would sound even better once they were broken in.

Good Stuff!

I heard these speakers from a retail store and really liked the way it produces bass, mids and highs. After ordering it sounded a bit flat but after 2 months of use, it is almost broken in and sounds great. Good speakers for a decent price!.

Awesome deal!

This is my first time using sound deadning and I can tell you that the installation was really easy and the diffrence was greatly noticeable in the sound level. I do not get any rattling what so ever. The product feels thick and of good quality. I would definitely recommend this to anyone trying to improve their quality of sound in their system. I can also hear the diffrence in road noise, it has been greatly reduced, if I had to judge, maybe about 75 to 90 % in noise reduction. This product is amazing!

pretty good

Now in my car the side door speakers are just mid bass but i went ahead and got coaxial because components wouldn't have fit. Anyways the are loud, decent mid bass, great tweets, cant wait to hook up a amplifier.

WARNING: when i was installing the 3/4 bracket didn't fit, and it was made for my car. i made some adjustments and got the speakers to go in without the bracket but do note it will not fit dodge neon !

Great Speakers

I installed 4 of these in my Jeep, powereed with a 200w amp and they are loud and have a very clear sound. Definitely a great value. I have yet to test their 'marine' capabilities.

Clear sound! Great mids! Overall awesome!

Nothing is better than having you speakers amplified! The clearity of sound increases significantly. I think for the money, these polks are the best on the market. Reputable company and a great product line. I have two Of the speakers in the back coupled with Polk 6x9 version that handles the same wattage in the front. Rockford Fosgate R400 amp sending 75 watts to each speaker. Had these speakers for about 4 years now and I've had a couple blow from cranking up the volume a little to much but they are cheap enough to replace every couple of years so it's no big deal. Definitely recommend!

Decent speaker

The speakers offer little to no bass but that wasn't a huge problem considering I have 2 rockford p3's. these speakers however do not offer a lot of mids either. The highs do get very loud though. Maybe if I would've amped them up that would've help with the mids. I've had the speakers for about 3 months and they are starting to rattle. However that is after turning them up to 35 (on a 60 volume scale) but most aftermarket speakers should be able to do that with ease. I'm not sure how these sound with an amp. But if you are not looking to amp these up and you have a sub that puts out pretty good bass.. These are not the way to go.

Nice sounding speaker

These speakers are very impressive. Very clear sound with decent bass on head unit. HOWEVER If you choose to install an amp with these speakers, you will be rewarded with clarity AND bass. My system has these two speakers and one 8" Infinity woofer with a 1600 watt amp. Installed with one speaker per channel and bridge the other channels to the sub. Awesome sound. Great speakers !!!

Great Speakers!

These are one of the best speakers you can buy without getting into components or needing to run an amp to them to make them loud. They are very crisp and have no distortion when the music is up louder. I would definitely buy these speakers again.

Door Speakers

Put these in the doors of my Silverado and they perform great!

Great Product, Great Price

These Polks have great low end. All round great quality speaker at a great price. Highly recommend!

Good value

Sound deadening works like it should came free so cant complain sticks well equal to dynamat

What the Doctor ordered...

37 coupe. Small cockpit but big sound. In conjunction with a 60 RMS Kenwood amp and an Infinity basslink. iPod as head unit, GLI, volume control knob, and Y splitters into the amp and basslink. Couldn't be happier.

Polk 6/9 Audio Speakers

I ordered the 6/12 speakersfor my Harley. This product is so Awsome, The quality of the speakers,the durability of the product is just amazing, I'm riding at speeds of 75 to 80 miles an hour. It sounds like i'm sitting in den at home listening to my surround sound speakers. Very satisfied. Order actually arrived before delivery date. Completely saitsfied with speakers. I would definetly arder again from this company.

Excellent Sound!

I replaced the factory speakers in my Correct Craft Super Air Nautique Team Edition wakeboarding boat. Sounds awesome! The sound is way better than any of the speakers that I tried out at the local stereo shops and I saved a pile of money by buying them through Sonic Electronix.

Great value

Nvx deadner was excellent on my door speakers' good quality.

By Noe on April 28, 2020 Verified purchase

THE BEST

I've used other sound deadener products, I always felt they were way overpriced. These, on the other hand, offer the best value and not just that, it's actually a lot thicker than the other deadeners I've used in the past.

By Anonymous on March 24, 2019 Verified purchase

good deadner

it dont vut like someothers i have used suchas stinger. it seems to be thicker. it was very easy to roll out bubbles. im going to order some more

By casey on February 28, 2016 Verified purchase

good speakers

Good speakers, kit contains a conversion ring which is nice. Sound is very clear up to about 1/2 of my radio's volume then distorts. This is because I do not have an amp and not the fault of the speakers at all. I would definitely recommend these as a budget replacement to door speakers, but they definitely need an amp.

By James on April 12, 2015 Verified purchase

Great affordable sound

Good product for the price. It just need more info about the use of the swivel mount tweeter.

Polk Audio db651

I recently bought a second set of these speakers to go in the front of my truck cab. I have to say that for the price they are great. I would recommend them to anyone that wants a clear high end sound without distortion. The tweeter in the middle sticks out a bit more than a normal speaker of this type but that doesn't make the speaker any less great.

Crisp and clean

I installed these in the rear of a RAV4. This was an upgrade from a single 5.25 inch paper cone mid to this coaxial comp. The difference is amazing. The factory speakers were very muddy and unfocused, with undefined sound and no staging. These Polks have beautiful definition and staging and give my back seat guests access to nuances in the music they didn't have before.
Installation was easy- I was able to simply connect the supplied leads to the stock wiring and thread it through a hole in the door panel. Physical installation required me to drill an extra hole for the one screw in each door for the mounting bracket. The speed clips worked fine for this and installation overall was quite easy.
My gripe are few. The brackets dont seem that robust, especially compared to the beefy construction of the speakers themselves. This would be an easy place for Polk to step up a bit. Second, unlike the matching 6501 component set , there is no way to drop the treble off on these. It would be nice to be able to match them to the fronts since this is likely a common combination. Third, I'm a little surprised by the loss of bass, given that I upgraded from a smaller speaker to a larger one. I'm still using the stock HU so maybe that plays a role, as does the fact that the bass is so much tighter now, but I do feel like there's something missing at the low-end now.
All in all, I'd highly recommend these speakers.

Great Speaker for the $$

Great speaker for the price. Clear, rich sound! Handles lots of power.

DB651 (not the slimline speaker)

After doing plenty of research I decided to install these in my 99 Toyota tacoma Xtracab. Was looking for a bit better power handling 2 way speaker and these filled the order quite well.

Pros: Excellent power handling speaker with plenty of highs and lows and the materials to handle high output with clarity.

Cons; These are not a direct bolt in into a 99 Toyota Tacoma Xtracab, you will have to do some modifying, but not much. Not really a Con per say, as I knew I would have to modify before the purchase.

Small but useful

This size only works for 1 pair of speakers, but it works great. It stick without problems, and it was easy to install. Quality is great.

Best value for sound deadener

I have bought several packs of this sound deadener after trying several other brands, I have had the absolute best luck with NVX. Great product and value.

By Savion on April 4, 2017 Verified purchase

nvx

this is a good product if you receive it in time to install with other products at the same time works well

good product

I have NVX insulation around my front and rear speakers and I would definitely recommend it to a friend. The insulation is pretty thick so be prepared to make holes or cut as needed for proper contact to mounting surfaces. Its pretty solid and sticks really well, and as far as I can tell it helps with sound but I would have to cover the whole car to really compare it with other sound insulation products. I would buy this product again

Great speakers

Bought this for a RV and I have to say WOW. The Bass this things put and good. I have two pair and the amp is a Hifonics-TXi-6408-R-B. The highs and lows sound great. The lows are great too. I would tell any one to buy these.

By JeVaughn on January 2, 2016 Verified purchase

Great product

Product is price well and seems to be very durable. This speaker can handle a lot of punishment. I love it.

These Speakers are unreal

I have these in all of my vehicles (3). They sound great and add a depth to the music not heard in other speakers.

Go Polk

I have never been disappointed with any speakers I've bought from Polk. These 6-3/4" went in the doors of my firebird and fit great. They are powered by 50w pioneer head unit and seem to be getting enough power for my purposes, but more never hurts!

In the hatch I have 2 RF 6x9's in ported boxes and amped 100w to each. This has a good stage for music; clean mids and sharp highs up front from the smaller polks, and more low end presence from the back 6x9s.

These are awesome for the price and they're marine certified so they should hold up fine to being swung around inside the doors, exposed to weather.
Low end Hz are somewhat disappointing, at least in my setup, but match these with subs and it would have awesome range.

Great Budget Speakers

I purchased 2 sets of these along with a set of Polk db351's for my dash. These were installed in a 2004 Trailblazer EXT and I have to say that they offer way more than I anticipated in terms of sound quality. I have the 4 651's attached to about 80w rms and the 351's running off of my head unit (17w rms).

I had a set of cheaper coax's previously and there is no comparison between those and these. They look great, feel sturdy, and perform way better than I thought they would. I would absolutely buy these again and would recommend them to anyone looking for speakers in this price range.

Through many communications with them and verifying on Polk's website, these do handle 100w rms per speaker. Even better deal for 65 bucks!!!

Solid Performer

Purchased these Polk db651's to replace the stock Clarion speakers on my boat and am very happy with them. They sound good and play very loud. I would definitely recommend them to anyone looking for a budget speaker. I will probably replace with the MM series at the end of the summer, as have added an amp and have Polk MM650UM's in speaker cans. Overall very happy with these speakers and all of my Polk products.

Polk at it again

As all the Polk coaxial's, these have a nice clear sound from the silk dome tweeter and plenty of bass. But putting the amp on them is the only way to fully appreciate their sound.

amazing

i just got these and put them in and they just scream i got these and the db 6x9 and it puts out great mids and highs i just gotta take out my stock amp and it will sound even better i give 5 outta 5 and great price

2nd set of these, highly recommended!

I started with replacing the factory door speakers in my 2001 Golf TDI 2 door and at that time I also installed Dynamat in the doors and along the rear side panels. WOW. Huge difference is hearing the sound at all levels.
Of course I then had to order another pair to replace the factory rear speakers. Again a very noticeable improvement in sound texture and quality. Very satisfied with the Polk Audio db651 product and with SonicElectronix.com for their low prices and fast shipping.

Excellent product!

I am running these with a Sony CDX M60UI, a pair of db521s and a Bazooka 8" passive sub. The sound is wonderful. Very crisp highs and soft lows. I have heard that they sound even better with an amp. Not much room in my little boat to mount an amp, but these sound so good, I really don't need one. With a 92dB sensitivity rating, a few watts will give you great sound. I would recommend these to anyone.

Best bang for the buck

Bought these speakers to replace the 4 OEM speakers in my 1999 Toyota Tacoma xtra cab. Fitting in the factory location requires the scoshe adapter plates #SAC-656, and a bit of work, but they will go into place behind the OEM grills. Compared to my OEM speakers, they sound great for a 2 way speaker. Thanks for the excellent customer service SE!!

Easy to apply

Received this pack as a add on to a speaker purchase, it applied very easy, didn’t cut up my hand unlike other brands. Seems to be working great to stop vibrations.

Great marine grade speakers!

Great highs and lows even without an amp. Used in a Jeep soundbar where they have to compete with open air flow. Easy install and noticeably improved sound. No more worries with rain!

Great Value

I would recommend this product simply because i have never had any problems with these! for the price you really get a much better quality. Polk audio never stops putting out great products

Good Speakers

These sound great as long as you give them the power they need. They wont come alive unless you amp them. Good quality and easy to mount. I'v been running them for a few months now and sound great.

love these speakers. Sooooo much clearer. Rear honda speakers were muddy and no clarity. The imaging coming from the back is more pronounced now. Tweeters are crisp and bass is tight. i may amplify these later with a four channel amp, 2 channels for the rear and bridge the other 2 for a sub. Totally happy!

this stuff is the best sound deadener on the market! I have used everything from the cheap stuff to the high end stuff and I gotta say this is my favorite. its thicker then most, sticks great, and most of all works great.

The sound dampening is very thick and sticky installed it on a 28 degree day and just heated it with the car heater it became very flexible sticks great the 2.3mm is equal to about 90mils witch is much thicker than most brands out there.

Good speakers

I bought these for my Audi A6 and they fit perfectly. Running them off an mbquart amp and they outperform the bose audio I had, and I only replaced the front two door speakers. They get loud and have good highs. Get an amp for these.

Great buy

These speakers were relatively cheap compared to other in its class.
The high end performance out of these speakers is unmatched but need to produce a little more bass. If you have a sub complementing these speakers, they are well worth the money. Polk is a world class organization and produce products that fall in line with their reputation. Enjoy!!

great sound for low price

I have them in a 08 scion xb and they are great for highs and mids they do great with my pioneer 3200 bt along with a alpine type r 12 I would recommend to any who want better door speaker than factory at low price.

Yea Polk

Put these in a custom built sand car and they sound great! This was the first set of Polks I've ordered and since then I have order 2 more sets. Best sound for the money. Highly recommend them.

Good for the $

I have these in my front doors and they sound great. Be aware that these work well with a nice clear signal. I didn't appreciate these until I got a new deck with pre-outs that send the signal to the amp at 4v. They now have a near audiophile quality after tuning them.

polk audio db651

Good speakers, great price. A great mid line speaker that really comes alive with clean power. I have db series front and rear in my Toyota 4 runner on a jl 500/5

good speakers, but incorrect rating

Put 4 of these in my toyota matrix, since they're really shallow they fit pretty well without much additional adjsutment in the car. They sound good too, i went with these over infinity kappas since it showed they were 100 RMS each and figured i'd save a little money and try these since they seemed better. I installed them with the amp I purchased. After a week 2 of them are already crackling pretty bad. I'm pretty upset that I pretty much just threw out money. BUT, this is not to say these speakers aren't nice, they're great. Shipping was, as always, fast from Sonic Electronix.

great coaxials!

These speakers sound fantastic and even at a SUPERB price!

Good quality

Got this for free as part of a purchase I made from Sonic. I bought a large sound deadener kit for my car. I came up just a hair short on deadener and then I remembered I had this. It was just enough to finish the job. Also this nvx deadener was much thicker and better quality then the other stuff I had used.

Polk is the way to go.

Excellent choice for the price !!!!! Planing to buy another set for my wife's car.

decent for the price, bright for my taste

Not a bad set of speakers but wanted matching front/rear, and they 651s was too deep in front for my application. Had these installed for just a month or so, but was overall quite happy with them- EXCEPT- they were very bright. Had to have a lot of high end cut to make my ears not bleed.

Smart Buy

I have owned these speakers for about 6 months now and found them to be very reliable. They are stock replacements which made them easy to install, and easily handle the extra wattage of my aftermarket headunit. Value wise, I'd say they are well worth it.

good speakers

Good speakers, great turn around time.

Good speakers

I have purchased these to upgrade the audio in my 1982 Dodge, and am very pleased with the result. I am driving them directly from the head unit, and also have a pair of Kicker 6x9s that I drive from an amp. The two seem to work together quite well. The Polk has a slightly more refined sound while the Kicker has a little bit of an edge, but together they sound great.

Highly recommended.

They like power

I am running only 45 x 4 amp, so at lower volume levels there's not much mid and bass. For someone looking to replace stock speakers and keep original headunit, keep this in mind. At higher volumes, they sound great and apparently can handle plenty of power. With my system I can't listen to music loud enough to get them to distort.

Does the job

Kinda expensive but works. Very easy to work with. I would buy it again.

works well

I haven't used this type of material for a while so nothing else to really compare, but it seems to have worked well. 90mil makes this product one of the thicker ones on the market, and considering the price, I believe this is a very good product. It did calm the resonance of the doors quite well. It doesn't make the car quieter if it is used alone, but it does improve the sound quality of the speaker. It goes on to the metal and plastic surface pretty well. Hopefully it stays there for a long time.

Great for Removing Vibrations for Better Sound Quality

This sound dampening material really does the trick. It removed the vibration from my door speakers and made the sound more crisp and clear. The only downside is trying to apply it around speakers, has to be cut and molded properly for a good fit and better sound, a little tricky, but still doable.

By Ryan on March 26, 2017 Verified purchase

Great speaker

What can I say, Polk Audio has maintained great quality through my years of being an audiophile. The db651 is the the best sounding 6.5 speaker out there for the money. Buy it here Sonic electronix!!!!

Superb sound/quality

I would definatly recomended Polk audio speakers the the listener of any music genre. Great quality, price, and of course customer support from sonic electronix. I did not have an amp running my speakers. Just a pioneer deck.

The best

The polk db651 have the best bass. They sound real good you have to try the Polk you will love them. The price is the best with Sonic.

Great value

Good quality speakers for the price and they look great!

great value and deal

the price was great, and i have grown to use Polk speakers in all my cars, a power amp in the 50-75 watts power range and you have a nice sounding ride.

Just get some

I can't tell you how this product compares to others because I've never used a sound deadener. But even just applying the speaker kit made a big difference. I tested the sound after doing one side to make sure nothing was rubbing because it was already a tight fit. The difference in volume was at least 3db from one side to the other with way less rattling. I will be doing complete treatments from now on. Thanks, SE for providing these for free with my purchase.

Very Good

Picked these speakers because of the look, price and good reviews I'd read about them and they were spot on about them. Been six months and haven't had a single issue with them and they sound Great!

Awesome Speakers

These speaker rock. I have them on a four channel hifonics amp giving them 110 rms a piece and they are loud and clear. Buy them, you wont be disappointed. Just ordered the db691 to match today and cant wait to see how it all comes together. Got 2 12 inch L7's and a kicker 1000.1 and it sounds like a concert! Thx sonic!

Polk db561

These speakers are crystal clear with no destortion, even at high volumes. i installed these in a 2006 monte carlo SS Silver, these went in the door panel. These polks blew away my stock speakers away. so clear, and clean, for the price its a bargain.

Great bang for the buck

Very happy with these speakers, made the stock radio sound great, in my chevy truck, now just need to replace the back ones

Works well

Bought 2 packs to install in my 4 doors with my speaker upgrade. It does stop a decent amount of rattle that was present in my door panels. I had to split one pack for two doors. Got a decent amount of coverage but I would suggest buying at least one pack per door for complete coverage.

Quality sound deadener

Great product, got it for free with my speaker purchase. Sonic is always hookin it up

good bass

Very good bass response. Great power handling capability, easy install.

Love my polk

I got this set about 5 or so months ago. I really like mine works perfect with my system, real clear over the bass. I also have the polk component set and love them, also works really good with loud systems.

great set of coaxials

These Polks we use heavily at our shop, they have a good sound and decent midbass, the perform well with after market head-units/receivers. for best sound thogh a proper component set is always better.

Also, Polk Tweeters, though Silk Dome, are notorious for being "harsh" that's not necessarily a bad thing, it's just their sound signature.

Hybrid audio makes some great coaxials that are worth every penny, but with any good speaker setup you should amp the speakers.

works as it should

thick sound deadener. works great for speaker installation but would recommend 2 sheets for speaker to really get a the benefit of it.

Good product!

They work well with my 1000 watt amp. The only thing, the built-in tweeters can not handle the power. The tweeters sounds distorted when I turn my volume up over 28. Its better for me to have component speakers. But otherwise the mid range speakers itself sound good when I turn the tremble down. I would recommend these as a starter for a econmic buy.

Polk Audio

Poor product. Only used a month and voice coils blew. Would not recommend.

Great for a boat

I installed 2 sets of these speakers in my 21 foot open bow boat with a Rockford Punch 200-2. These things get loud and clear and the
bass is really good if mounted where there is a compartment behind them. Out of the box highs are a little harsh but acceptable and can be toned down if your head unit has the capability. I did a some adjusting and i am impressed with how good they sound. I plan on adding another set.......soon! Get these you won't be disappointed!!!! I gave them 3 stars on durability because i just installed them and the grill has some spacing as far as protection.

Mids and Highs Good...

For whatever reason I did not have any bass with these speakers in the doors of my 2005 Hyundai Elantra. The factory junkers had better bass. However, if you are using a subwoofer they will sound nice.

GREAT CHOICE!

I purchased these with the component set as well, the money i spent is money well spent. They are clear, loud and the sq is impeccable.

Good Spk

Good speakers for the price. Using a Nak amp to power them. Speakers would be good for any normal application.

Great value

They are exactly what they are and you can never go wrong with nvx products.

These speakers are great for the price. They have excellent mids and highs. I have 2 pairs for front and back and powered by a old school kicker amp which gives them about 65w rms each. They get very loud and don't distort very easily. For the price I would definitely recommend them.

Polk Audio db651

I put these on my Harley Davidson Streetglide with an ARC audio 2 channel amp and now I can hear my tunes at 90mph+ even with a full face helmet on!

Speaker

Speakers sound great.

Outragous sound

Golden crisp sound rather hitting highs or lows. These polk speakers hit hard an clear! However dont expect bass from these speakers, they arent made for that purpose, but if you also have subs the sound in your car will be perfect. Hope this helps- Brad.

good speakers

These speakers sound very good. I put them in the doors and they sound great. good balance between bass and treble.

Great sound

These speakers are crystal clear without sacrificing bass. Replaced stock speakers in our boat and added a 10" sub. This thing rocks on the water.

less doorskin ring.

Put these behind the speakers on the door skin and it significantly reduced the resonant frequencies in the vocal range, which before treatment made the speakers have a bit of reverb effect during speaking vocal range.
Much better. Doesn't sound like I'm in a sports arena anymore.

By Dylan on November 22, 2022 Verified purchase

Seems like it's helping.

Got this free with new speakers, so opted to use it during the install.

With the factory speakers, when cranking up the volume, I could hear the door outer door panel resonate when outside the car. After installing the new speakers and this Deadener, while I got my music cranked, and it seems like it's louder than I was playing the old factory speakers, I no longer hear the resonance of the outer door skin when outside the car.

So, it seems to be doing its job.

However, time will tell if it stays in place or falls off. Or worse melts and creates a mess.

By Brandon on April 4, 2021 Verified purchase

Awesome

Very clear and crisp sound I would recommend these to anyone and for the price you can't beat it

Amazing if you have subs

A combination of these door speakers, Polk Audio 6'9" in the rear deck, and 2 15" MTX subs in the trunk sounds absolutly amazing. These speakers have a very very loud high end. Like if a high pitch sound plays, you risk a chance of busting your ear drums!! So i turned the high end down just a bit, and a combination of that, and the subs makes for a 10/10 sound system.

Nice sound, not much bass

Got these speakers to replace stock Kia speakers. Ended up keeping the stock speakers because these ones have terrible bass output. They were great for full range, almost making music sound 'live' - everything was good but the bass, so they had to go.

sounds good

My set up is a simple consisting of a pioneer head unit, jbl gto 1004 amp, and polk momo (mm1240) subwoofer. The excel in both the department i.e. sound quality and sound pressure level.
I was surprise to see that this speaker sounds great without any distortion, secondly the build quality is upto the mark. The sound quality was good not on par with the momo series.
Cons: As compare to the polk momo subwoofer I found that this speaker were not keeping up to my expectation.

good quality product at a good price.

speakers are used on atv stereos that are custom made by me. So far no issues with speakers and they sound great.

World of difference in a Zuk !

Replaced stock very cheap, tinny rear door speakers, 6 1/2", in 2009 Suzuki SX4 Crossover and am very, very satisfied. Had NO bass before and the extra benefit is the very crisp midrange now as well. Snipped connector plastic off of old speakers, snipped wires at cone and soldered to the tabs on the new ones, so still have a plugable design; necessary to drill my own holes for mounting and these are a perfect fit for the door panel ! This Zuk is easy to work on. And your prices are great !

Polk Audio db651

Put 4 of these speakers in our boat. They have a very clear sound quality. Good bass for this size of speaker.

NVX sound deadening works like magic!!

At first I was very sceptical because I've always used a different brand that cost twice as much. Thinking that it cost more because it's better had been my biggest mistake. When it comes to this part of any audio install, always always take the extra time to eliminate any rattles and vibrations. When you're spending money on top of the line audio electronics always compliment your install with NVX sound enhancing/deadening products. I promise you'll be amazed at the sound quality difference.

By Cameron on December 16, 2016 Verified purchase

Good bang for your buck!

I purchased these along side the DB691. I powered them first by an aftermarket head unit, then a mediocre under-powered amp, and finally by an Alpine amp more suited towards the RMS ratings of this speaker. In all three setups these speakers were leaning more on the 'bright' side. However, after a month of appropriately powering them with the Alpine amp they finally started to break in and sounded a lot more full. Even though they sounded a little better than right out of the box, there's still a lack of mid-bass. As long as you have a sub in your setup you should be good to go! Overall, I'd say these are a great bang for your buck!

A must have for Harley Davidsons

Just perfect, if you own a Harley davidson with a fairing get these speakers

awsome speakers

I payed damn near twice this price, mostly becuase it was near 3 years ago, and from a retail store. but none the less, the speakers perform as though they $150+ speakers, like noted before they only can truly be appreciated with an amp, I have them powered by an eclipse EA4000, 75 watts a speakers rms, EXCEPTIONALLY sharp highs, and i mean SHARP,and not to bright. once they are tuned right, they sound amazing, I have 4 of them, and 2 in the door and 2 on the back behind my seat's that use the trunk as a bass tube to give it a little more thump, with the bass turned up, and the low's turned right, they hit so nice you'd swear their was an 8" sub back their.

Good speakers

Good speakers have had them for over a year now and they still play great, clear sound and they were reviewed on one site as being one of the top notch 6" speakers and they were right.

Great Speakers 4 Great Price

I have an 02 Honda Accord 4 door. Installed the Polk db651's in my front doors. For the first 3 months they were powered by 50 watt rms per channel head unit and sounded great. I planned on putting an amp on them from the beginning, but didn't, due to financials. After a few months I purchased and then installed a West Clast Customs 1600.4 amp (also purchased from sonicelectronix - $100 - free shipping - Great price for Great amp). Without an amp the db651's were already really crisp and clear, even at higher volumes. I didn't think they could get much better, but with more power and better tuning ability, the Polk db651's SOUND EVEN MORE AWESOME. Needless to say I would def buy these again. As a surprise for Christmas, I am planning on replacing all 4 of my wife's speakers in her 2011 Honda Fit with al db651's. Thanks Polk and Thanks Sonicelectronix.

Polk Audio DB651 Speakers sounding great in boat after 6 months

I put the Polk Audio DB651 Speakers in to replace some 8 year old speakers. They sit exposed, but under shade on the center console of my boat in the Florida sun. They sounded great day 1 with nice tight bass, clear mid-range, and bright highs. I listen to a wide range of music and I'm pleased with the sound. If you are looking for head banging bass, you'll need to add a subwoofer. For me, they were reasonably priced, durable, and sound great.

Awesome stuff

By Matt on December 11, 2023 Verified purchase

These sound great!

These speakers are just about the best around. The 1" tweeter gives you that high end boost that you always need. Before I bought these, my Sony speakers were being drowned out by subwoofers, now I have a clear crisp sound coming throughout my car. If you are looking for reasonably priced great speakers then these are for you. One of the flaws in Polk's design is that the cool looking grills that you see in the picture won't fit in most cars. I really didn't care about the grills after I heard them for the first time though. These speakers are great for any type of music whether it is rock, hip hop, or even classical. They give you a great sound in any environment.

I miss them already. if you like music and are a musical guy use these you will love them!!!

I have replaced speakers in three vehicles and a boat, this year. I greatly regret the two that I tried to save a couple bucks on by buying slightly cheaper speakers. These Polks are FAR above the others in sound quality

Great speakers

These speakers sound great on my pontoon boat, They look nice too. I would buy again.

Nicer sound at a low price

I replaced speakers in my 2001 Yukon which were all treble, no bass and one rear speaker did not work at all. These are a big improvement. Unfortunately the speaker that didn't work at all has a wiring problem and new speaker does not work there either.
Only catch was having to solder the old wiring socket to the new speakers as they came with no compatible sockets for my car. Not a big deal, but I have replaced other speakers for a Buick that came with adaptable connectors and thought these would be the same since they were listed as fitting my car..

Great Sounding Speakers

I purchased these to replace the stock speakers in my Honda Goldwing's front fairing. They sound a lot better than the stock ones.
I would recommend then to anyone with a wing.

Party Pontoon

I installed 4 of these speakers on my Pontoon boat along with a Sony XM-604M amp and they sound great! Plenty loud and just enough bass to massage your bum when sitting on the seats LOL. The first time out we got yelled at from shore to turn down the music. It was the 4th of July so we kept rocking anyways... I just hope they hold up to the outdoors.

Good deal

I installed these speakers on my Harley streetglide and love them. Crystal clear sound and very durable.

Crisp and clear

Nothing bad to say about these speakers really. They fit perfect in my vehicle with the mounts provided and are extremely clear. I would have liked them to come with some wire and female connectors like some others I have bought in the past have. Great product though

Awesome product

The transaction was super easy. The speakers were brand new in box just as described. I highly recommend this seller.

Good Speakers

Have had the speakers about two month now but them in a Polaris Slingshot and am very happy with them. Good sound and music up to 70 mph.

Polk db651

Love them so far in my motorcycle faring. They go great with my db6x9s in the faring nice clean sound.

Great speakers

These speakers sound great, they are affordable, and look great!

Polk 6.5 speakers

installed in my Harley Ultra last week great Speakers with R F Amp.
Can Hear my Stereo at 80 mh now

Great!

10 out of 10 speakers, tweeters come in well, head unit works great with my subs due to so many different options and settings

great sound

great sound the only concern is the speaker grill would have preferred a mesh grill where no damage could be caused with small children putting things into the speaker

Best bang for buck Marine

I've installed quite a few pair of these mostly side by side's lots of mud and water 0 problems they sound amazing they love power .

Nvx sound deadener

This 2 pack of 10"x10" sound deadener is perfect for tight spaces. It helps with vibration and allows you to hear the music better without rattling noise. Definitely recommend this kit

best speaker for the money!

these are great at holding the mids and lower end bass. They also still sound great even in places where typically you would sacrifice bass like older cars that they didn't really focus on audio quality much.

Polk Audio Marine Speakers

Installed a set of these in my boat. Really nice set of speakers. Would purchase them again if needed. Great price for Marine grade speakers!

By Tamara on December 29, 2019 Verified purchase

Great speakers for the price!!

These speakers are loud and clear and handle bass well. i pushed 60 watts rms thru them crossed at 80hz and they screamed with well mids and highs and decent lows. they are best coupled with a larger speaker or sub that can handle the lower octaves as these are not specialized for that. These were used in many vehicles and always got great reviews from customers. will keep on buying these in the future. give them a try if on the fence.

Very nice Polk speakers great sound,would recommend them!a lot better quality then the old ones I had!

Good speakers

Replaced factory speakers in all four doors of a 1999 Bravada. Had to drill new screw holes in the speaker mounts but the speakers fit the hole perfectly. Good sound for a factory head unit. Would sound better on an aftermarket head unit and amp.

polk speaker

polk spearks are great i have them in 4 cars great sound

Cyber Week Dream deal

Got these during Cyber week; always loved Polk Home; equal to the old school JBL stuff when it was still USA built (Not the china junk) these sound amazing. Cyber week price was a bonus for Polk quality. Had Rockford Punch before. These seem a touch easier to fine tune the head unit to get optimal sound. Though i do wish they had these in 3-way for a mid range or super tweeter that would be sweet, so only 3 stars for features due to that.

Great Motorcycle Speakers

These are good speakers for a motorcycle. I purchased these to replace the same model speakers I have in the bike. I damaged the present speakers by turning the gain up too much on the amp. Other than losing a small section of frequency response, they still sound really good. I had these same speakers in my other motorcycle for years, and they still sound great!!

Great set of speakers..!!!

I purchased the Polk Audio DB's because a God fr8end recommended them. I have installed them and WOW.. They sound incredible, excellent highs. I have them hooked to the factory but plan on getting an amp very soon. I know that they will sound even better. I highly recommend these speakers.

Excellent Value - Clean and controlled mids & highs

I purchased the Polk 651's as replacement drivers for my 2016 Mustang GT. The factory speakers in my Mustang distorted horrible even at moderate volumes. As I didn't want to replace the factory head unit I needed something with good sensitivity, built in high and low pass crossovers, and something that would not require modifying the trim panels in the car. The Polk 651's checked all those boxes nicely. I should mention that I did need to disconnect the factory tweeters on the components in the front and would recommend doing this on any car where you are going from a factory component to an after market coax.

The Polk 651's did not disappoint. The speakers play with more than enough volume off the factory head unit and are clean and clear. The added detail to the mids and highs over my factory speakers is very much welcomed. The bass, while present, is not booming. For those that listen to a lot of bass heavy music, you'll want to pair these up with a sub.

Overall I was able to reach all of my goals at a very reasonable price point. Next step will be to add a sub to finish off the stereo upgrade.

Solid Value - Clear and detailed Mids & Highs

I purchased these speakers to replace the factory drivers in my 2016 Mustang GT. The factory drivers would distort (painfully so) at even moderate volumes. I chose to go with coax vs component drivers to avoid the need to cut out the factory A-Pillar tweeter and mount a new one (instead I simply disconnected it).

The Polk 651's became an immediate front runner. They have a high enough sensitivity to let me run them off the factory head unit and the -12db built in passive high and low crossovers help ensure the right frequencies go to the right driver.

After replacing all for 6.5's in the Mustang with the Polk 651's the sound difference was night and day. Clean crisp mids and highs with minimal to no audible distortion. Bass, while not booming, is present. For those that want a bass heavy speaker, these are not them. However, paired with a sub, they make for a perfect cost effective upgrade.

Good frequency response

I can't possibly compare these to stock as the stock speakers previously in place were in fragments. I had to modify front doors on my 02 GMC crew cab pickup. Drilling hole in the front doors was one of the modifications. Then splicing into the speakers wires to tie into what the Polk speakers needed to hook up was second. Rear speakers were easier due to the mount on the existing speakers. Then splicing once again into speaker wire to prepare to hook up speaker. The speakers sound tight and bass response is good for a 2 way speaker. The gasket in the install kit help with sealing sound. The install took me about 2 hours with lunch in between.

Superior marine speaker

Great speaker for wet applications. Comes w grilles and adapters and all hardware. Has the capacity for moderately sized amps. Great two way selection for your boat or cycle

Awesome!

I purchased 6 of these with my boat, literally these are the best 6.5's I've ever installed, I've ran many many brands and I can only tell you one thing. I'll be installing these in everything from now on, make sure to put them on an amp, a Head unit isn't enough power to get to their full potential. 4 of these on my tower, with 2 8" MB quarts and it sounds absolutely amazing!!!

Total of 16 speakers, all Polk with the exception of the MB quarts- absolutely amazing!!

killer rear speakers

i installed these in the rear of my car and good golly do they bump a really nice addition to the lower side of my system paired Infinity 6030cs for my front speakers it sounds great

Superior Sound!

It was not easy to install but the sound makes up for the hard work. For the price it really is a great deal.

Good product

Shipping and speakers were exactly as advertised. Decided that they wouldn't handle the power or serve my needs and only installed for few minutes.

Great speakers, awesome price

I bought these for my boat to replace the poor quality OEM speakers. Great speakers at a great price

GREAT SPEAKER

Great speaker for a custom pvc pod in a can am commander

Harley Speakers

Outstanding sound quality. I still need an amp to help with overall deck output. Speakers are ROCK solid.

Sound for boat

These speakers were easy to hook up and the sound is great.

Good speaker for money

Bought as replacement for factory speakers in my 2004 Electra Glide.
Sound is much better, makes want an amp now.
The speakers handle my 20 watt Harmon Karmen full blast, distortion only from maxing out headunit.

Excellent product!

Nice looking. Great sound. Good price. Installed in ice chest radio.

Great little package

Good speakers for the price. I have them in my jetski tunnel along with a pair of polk 5.25 speakers driven by a Pyle marine 400watt amp. Mid range and highs are pretty good. Bass gets a little distortion when cranked. All in all....good for the price

Great Door Speaker

These speakers are clear, crisp and can take the power of a great amp with ease. You literally can hear mids and his in the midst of a great sub.

Polk Audio db651

The product information indicated that they were replacement speakers for the OEM speakers. Far from it. The original mounts had to be modified to accept the replacement speakers, the wiring had to me adapted to make the connection and the design of the speakers would not allow the door panel to be replaced without modification. the adaptor bracket and cover bezel sent with the package are totally worthless for use with this vehicle. I am almost afraid to start on the installation of the db351 speaker installations.

Excellent Speakers

I have been a Polk Audio fan for many years. These speakers sound great, are well built, and look amazing.

Great Speakers & Sound for the $$

I owned Polk Home & car speakers in the past. I have not owned this particular series but am very impressed. Has good bass extension and clear highs. I eventually added a sub and put the High Pass Crossover at 120. Clear as a bell. Highly recommended at a great price.
