Priced Per Pair

Speaker Specifications

Series
This is the manufacturer product line of speakers.
db (Polk)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6-1/2" (also mounts in 6-3/4" w/ included brackets)
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Silk-Polymer Composite
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Mica Injected Polypropylene (MIPP)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
180 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
60 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
92 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
35 - 22000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Yes
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
1-5/8"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
2-5/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5"
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Yes
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Sastifying Product

October 29, 2010

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.

kind of tinny sounding

July 9, 2014

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.

ok speaker exagerated highs

July 9, 2014

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.

Crisp and clean

September 18, 2013

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.

Very nice coaxial for the price

May 29, 2013

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.

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.

good speakers, but incorrect rating

March 4, 2012

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.

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.

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.

Incredible speakers (especially for the price)

November 22, 2011

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.

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!!

Decent speaker

August 27, 2013

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.

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.

January 30, 2012

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.

December 12, 2011

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.

Polk 651

July 2, 2009

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 for the price

April 19, 2014

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.

All round good speakers

September 17, 2013

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.

Nice sound, not much bass

October 24, 2011

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.

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.

Go Polk

October 6, 2011

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.

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.

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.

DB651 (not the slimline speaker)

January 9, 2011

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.

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.

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.

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!

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.

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.

Love em'

October 13, 2012

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!

Great for a boat

June 27, 2012

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.

great set of coaxials

June 21, 2011

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.

They like power

November 15, 2010

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.

World of difference in a Zuk !

October 23, 2010

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 !

awsome speakers

November 18, 2009

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.

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.

Good bang for your buck!

July 19, 2012

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!

Polk Audio DB651 Speakers sounding great in boat after 6 months

May 4, 2012

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.

Great Budget Speakers

August 2, 2011

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!!!

Amazing if you have subs

December 17, 2014

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.

sounds good

May 19, 2012

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.

These sound great!

July 11, 2008

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.

Great speakers for the price.

September 27, 2014

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.

Best Answer: Great addition to my bike/trike sound system, having it in an enclosed area limits some of the thump (not much). I also upgraded the speakers to Polk marine speakers, sounds great. One thing to remember, it is open air sound, more watts more sound.

What is the difference between db652 and db651s?
A shopper on Dec 16, 2014
Best Answer: Hello,

The "s", at the end of db651s , implies it is the SHALLOW MOUNT version of the db Series 6.5" . In the features and specs, you will see 2-5/16" vs 2" , when compared to the db651. In addition, because the db651s is Shallow, it will not travel as far and therefore will not be able to reach as low of a frequency range as that of the db651; which is also seen in the specs - 35hz vs 55hz .
