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"
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 Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
3/4"
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.
165 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.
55 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).
50 - 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.
2.00"
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.
2.25"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5.00"
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.

Very good sounding speakers

September 17, 2013

I purchased these speakers to replace the old completely worn out speakers in my Chevy truck. I had to modify the stock speaker mounts to fit them but they fit in there nicely now. The sound is really good. Sounds better than it ever did before. They are a good value for the price. I recommend them.

Solid replacement

September 20, 2011

Major difference in sound from the factory garbage that these speakers replaced, even without amplifying them. Running them from the 45x4 head unit is sufficient, but would probably benefit from separate amplification. Good highs, great mids, but you want to cut them off and block 120hz and below.
Did not fit, even with the included adapter, but a drill bit takes care of that no problem.

Superb price/quality & value

August 8, 2013

The Polk db651s are perfect for getting articulate mids and highs in either a car of boat application.

They are equipped with a basic crossovers mounted on the speaker terminals (6db slope) however to sound clean they will need a high pass filter at about 60-80Hz for eliminate the lowest frequencies which will otherwise distort the sound.

Time will tell how long they will last in harsh environments like marine use but thus far (6 months) they seem to be holding up.

For automobiles the 6.5" coaxials will produce more low end such as midbass because of cabin gain however on a boat or any other open air vehicle (golfcart, jeep, ATV...) they will require a subwoofer to augment the missing low frequencies.

Once set up correctly they will sound surprisingly good with very detailed and smooth output.

For the price the value is highly recommended!

May 21, 2012

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.

Great Product!

March 16, 2009

I purchased Polk Audio from Sonic Electronix because of the wonderful price listed on their site, that was far different in comparison to the retail store price. They were not only reasonable, but arrived in a timely matter. When the speakers were installed the sound quality was absolutely wonderful! I felt as though I had a brand new sound system in the car. When it comes to products that are inexpensive but superb quality, I'd most definitely purchase from Sonic Electronix again.

Recommended to me... now I'm convinced!!

December 17, 2008

The Polk Audio db651s speakers came highly recommended to me by my local audio professionals. (And I did listen to as many different brands as I could before I purchased ). They have transformed the audio environment of my vehicle... they sound awesome. I just can't keep the volume down because I can now hear the full range of sound provided by CDs, iPod, satellite radio, and even the FM tuner. They are driven by my Kicker amp and I've added two 8" subs with a pair of tweeters up front to enhance the spectrum of sound. Make no mistake, the Polks handle the largest share of load with dramatic ease. I have yet to hear any distortion even when pushed hard. Believe me, for a pair of small 6 1/2" speakers they can really deliver. Now I am but another who recommends these Polk Audio speakers.

Polk db651s

November 21, 2014

I put these in my work van and it souds like I am in a different vehicle.
The sound is much better than stock speakers, and that is running the
Polks with the factory radio. I'm glad I bought the shallow mounts,
because the tweeter on the regular db651 speakers would have not
fit behind the factory door panels. If you are looking for a great factory
replacement I would highly suggest getting a pair.

Big sound outy of small speakers

August 26, 2013

When you buy small speakers (because thats is all the room you have to install in) you really don't expect to get much bass sound out of them.
Well, I was very surprised at the great all around sound I got out of these Polk db 651s speakers. I put them in a smart car and they sounded way better then I ever thought they would.
For the price, they can't be beat!!

I have these in my sound (roll) bar in my 2014 Wrangler. They sound really well with the JVC deck I installed and were even better when pushed with an Alpine amp (KTP-445U). Install was easy and I couldn't have asked for a better speaker. Easy to install.

If you own a wrangler, I would seriously recommend these. Another piece of advice is poly fill the sound bar. It does help out with the overall sound.

March 30, 2014

I've tried other brands at similar prices, but for the money nothing beats Polk Audio (especially when paired with a pioneer head unit). This model is the shallow mount as opposed to the regular DB651.

If you can fit the DB651 instead of the DB651s, go with the non-s model. It has a slightly bigger magnet and will give you a better low end response.

All in all, Polk makes some great speakers. When I bought these from Sonic they were priced at about $65 /pair which is a helluva deal for these speakers.

A Little Disappointed!

November 10, 2008

Bought these because they were on sale and got them at a really good price. But, to me, they don't sound like the speaker they are cracked up to be. The highs and mids are pretty good. The low end is really missing. I put these Polks in the doors of my Nissan Frontier, replacing the OEM speakers. The OEM's sounded better. Yes, the truck has Nissan's upgraded audio system with 6-disc changer and the little sub in the back center, so it already sounded pretty good. I thought these would make it even better. They don't, and that's a little disappointing for such a highly rated and relatively expensive 6.5 in. speaker.

Polk db651s

March 11, 2009

Mounted these, along with a Pioneer sub and 4 other speakers in my '68 Chevrolet P/U resto-rod. These are the main speakers mounted in the kickpanels. They produce excellent sound and good volume. These speakers were almost too deep for my application, but would be OK for most others.

If you want an economical 6 1/2 inch speaker that looks great, and produces excellent smooth sound at normal to loud volume these are an excellent choice. Great value for the money! Much better volume for the power than you get with 3-way designs...

Same great Polk Quality.

March 28, 2015

Just installed four of these in my 2000 Silverado. Two each per door in a fiberglass speaker pod I made using the OEM mesh speaker grill.

They weren't very impressive just on the radio but It also didn't feed them any reasonable amount of power for two per channel. However these things LOVE to be driven with decent power. I am running them on a Rockford Fosgate P500-2 @ 250watts RMS each channel and these speakers absolutely come alive and ask for more. Great mid bass kick, vocals, and highs without the slightest distortion. The box rates them at 55w rms and 165w peak and they are taking a solid 120watts rms per speaker and loving it!

I would absolutely recommend these speakers and Polk in general to anyone and I will be buying more of these to fill in the rear very soon.

I bought these because they are one of the few 6.5" speakers that can fit in the front doors of older Civics (with the included adapters).

Polk-a-dots their I's and crosses their T's

November 4, 2014

What I mean is that Polk thoroughly addresses every aspect of audio engineering in a way that leaves no room for negative critique. I could go into describing all the subtle methods Polk uses to improve the sound of their speakers without resorting to flashy audio voodoo, but you can read about that in their product sheets. Suffice to say that these speakers sound marvelous...clean and precise. No, they don't reproduce the last couple of octaves of low bass, but no 6.5" speaker can...whether it be home or car. These are simply some really sweet speakers, thanks Polk Audio.

Yes, I like Polk!

August 11, 2011

I purchased the Polk Audio db651s. I tend to prefer Polk products because they sound great and are durable in the humid Houston heat. I bought them in the early Spring and they are lasting through their first Houston Summer. These speakers tend to get the most heat because they are on the rear deck and get the most heat from near direct sunlight. I've owned other Polk speakers in the past specifically because they last through several Summers before I have to replace them and the price I found them for here is really great!

Great for the money, want more Bass

December 19, 2010

I would recommend these to anyone upgrading from factory speakers. My only complaint is that I looked at some Kicker 6.5's in a store, and they had much better bass. (I'm not running a subwoofer). However the mids and highs are brilliant and clear on these speakers. Bargain for the money. If you have a sub, bass is a non issue. If not, I suggest you compare before you buy.

Awsome 6-1/2

December 7, 2007

I put these in my front doors of my 96 accord and they produce excellent highs. They are extremely clear, and they get very loud. I suggest these speakers to any one on any budget.

Polk Audio db651s speakers

December 9, 2011

I love these speakers. I installed them in my 2000 Toyota Avalon and they sound absolutely great! I already had the JBL system in my car and the speakers were getting old so I upgraded to these and couldn't be happier. Thanks Sonic Electronix for a great price on some great speakers.

Sound is perfect

August 8, 2011

These speakers sounds great. I'm running these off the head unit and sounds great without a amp. Which will save you some cash. Do not buy these for bass its for the highs and mids. So if you want a bass buy a sub.

Great for the highs

April 18, 2011

These speakers just scream! They are great for the highs but lack a little on the low end, make sure you got a sub and probably some ear plugs when you got them cranked!

Polk Audio db651s for my front speakers in 06 Civic sedan

July 20, 2010

Great speakers and they do not require an amplifier. They play pretty loud, and I have them normally set between 11-19 volume out of 40 (max) on my car's stock sound receiver/in-dash. I have them connected to the front doors of my car, and they run with my 10" subwoofer in the trunk. Very crisp sound, may be a little too high for some people, but you can set the treble lower in your car's sound receiver. It has some nice bass as well. Good quality speakers, and worth the money.

March 11, 2009

Hey well i order these for my Honda prelude and damn they scream. If you like the treb. then you will love these for the price. The one thing they don't have much of is the mid bass but hey if you want the then get some subs, right, right. But no these are good speakers i love and i only turn them up half way and that is plenty loud for me. I love to jam too.

Giving up to its legend

October 25, 2007

Polk has always been one of the BEST companies for audio solutions. Glad i stumped upon them 5 years ago. I had these same pair but older model and they still kick. I bought theses to go in my saturn because i know what quality i was getting. once again polk murks it again with there new year model. Appearance wise, the grill and tweeter face is beautiful, everything is in a seamless design, and they hit the LOWS like none other, for a 6 1/2 inch speaker. I can turn them up and they don't peak out. I bought theses pair 2 years, just bought then last week and will recommend them to anyone who wants something that will put out whatever you give it

Better off with regular db651 coaxials

May 29, 2013

I purchased a set of db651s for my front doors, thinking that the "slim" speaker would be a better fit. I also purchased a set of db651 for my rear parcel deck, as space was not an issue. Upon comparison, I discovered that the db651s require the same mounting depth as the db651. The "slim" part is only the TOP of the speaker. To make the top slimmer, the cone diameter is slightly smaller, and the tweeter is mounted in a fixed position. I ended up installing the db651 in the front doors, because the slightly larger cone area would play louder, and the tweeter can be aimed. I would bet that most people who buy the db651s could get away just fine with the db651 -- which is a better speaker.

I bought these for my Toyota FJ cruiser. After installing them in my doors I did not think they had enough bass, so replaced them with some Kicker 6 x 9s. But I did put these in my Nissan Frontier in the rear doors and like them very much in that spot. For some reason they sound great in that truck.

These speakers are outstanding in sound quality, and are instant gratification after install.
What you should be aware of is that the model of automobile it says it will fit ....is not always so. I have a Jeep grand Cherokee , and had to modify the opening to install them.
Having said that...it only took an hour and I am very pleased

Really Nice Speakers

December 17, 2010

These speakers sound really crisp and clear. You will hear every single note in what ever music you listen to., Like everyone else says, the bass is really low so that's why I have 4 of these in my SUV with a 12' Kicker subwoofer. Very much worth buying at these prices. And customer service is A+.

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.

This is for 1990 Mazda Miata. Cutout hole is 5 3/8", Mount holes on a 6 1/8" circle. Will the Polk db651s fit? Do you supply any kind of plug harness for the speaker or do I just solder the wires? Do you recommend and sell a backing cup to prevent rain and moisture on back side?
A shopper on Feb 21, 2015
Best Answer: Hello,

The db651s will fit your vehicle, and we suggest the Metra 82-7500 bracket to help with the install. Moreover, you Can use the Metra 72-9300 speaker harness, but we often suggest saving yourself the money and simply figuring out the OEM polarity for each location.
