Polk Audio DXi651

Enjoy your music even more

Go ahead, circle the parking lot till your favorite song is over. Polk Audio's DXi Series speakers will make you want to hit "repeat" so you can hear it all over again. Polk uses a high-tech approach and ideal materials to give your tunes an exciting new edge.

Precision woofers showcase your music

The DXi651 speakers feature 6-1/2" polymer composite cones that are lightweight and stiff, so they can create a big sound with minimal distortion. Polk analyzes their drivers in motion to ensure that cone movement is even and precise. Polk also uses laser imaging to craft woofer cones that are perfectly balanced to resist distortion-causing resonances.

Aluminum dome tweeters broadcast detailed sound

Each 3/4" aluminum dome tweeter brings out the high-frequency highlights in your music, so you'll hear every detail of your most enthralling musical moments. From an intensely quiet acoustic pluck to the most exhilarating electric solo, it'll be a very entertaining ride.

Product Highlights:

  • 6-1/2" 2-way car speakers (pair)
  • supplied adapter rings allow for fit into 6-3/4" locations
  • polymer composite woofer with butyl rubber surround
  • 3/4" aluminum dome tweeter
  • power range: 6-60 watts RMS (180 watts peak power)
  • frequency response: 35-22,000 Hz
  • sensitivity: 92 dB
  • top-mount depth: 2"
  • warranty: 1 year

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Product Research


High Efficiency Design: The Polk Audio DXi Series speakers feature a high efficiency design; meaning better sound and more volume using less power.

Dynamic Balance Driver Technology: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Klippel Optimized Components: For a driver to reproduce complex sounds accurately, the cone must move exactly the same distance and manner in both directions. The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Polk optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Composite Cones: Each speaker features a Dynamic Balance, Bi-Laminate composite, polypropylene cone woofer. These composite cones feature tremendous stiffness-to mass ratio, resulting in faster transients and finer detail.

Rubber Surrounds: For a smoother response and improved durability, the speaker uses rubber surrounds.

Aluminum Dome Tweeters: Each speaker features a 3/4" aluminum dome tweeter for clear, accurate highs. Once the speakers are mounted, the tweeters can be tilted (approximately 25°) for optimum imaging.

Polk Audio DXi651

Written By AKaudio, Arizona on Monday, March 23, 2015

Crutchfield Customer Review (What's this?)

Bought the Polk Audio DXi651 for a 2004 subaru Forester X. Had good set of Polks in my 96 legacy. These are not so good. The spec indicates response to 35Hz on the low end. I measured the free air resonance frequency fs = 118Hz. I couldn't post the measurement data of impedance vs frequency. Put them in any kind of enclosure and expect this to raise somewhat although the compliance is pretty stiff so the door panel compliance is probably negligible. This explains the complaints of no bass. In contrast I measured fs = 83 Hz for the original subaru speakers. Also the noticed an erratic impedance of the crossover/tweeter at the higher frequencies. They have a little more on the high end then the original subaru speakers but by the time they go in the factory door panels it is not much of a benefit. The loss of bass is inexcusable in a 5.5" driver. The main problem is that the 35 Hz spec is misleading. Its a second order system with 40/db decade from fs. The spec should say -20DB@35 Hz.

Pros: Fit with brackets and wiring provided

Cons: Bass response

Good replacement for factory speakers.

Quality speaker for the price. Replaced factory speakers and these sound better.

Pros: Easy installation. Quality product

Cons: Bass not as strong as expected but still better that factory speakers.

Meh...not impressed

Written By IVI Guy, Oregon on Saturday, February 14, 2015

Crutchfield Customer Review (What's this?)

I bought 2-pairs on sale for my 2012 Impreza, a set for the front and a set for the rear. Last year I replaced the factory head unit with a Pioneer FH-X720BT, not high end but decent enough for the money.

First I installed the rears then fired up a few songs to make a comparison to the factory speakers. I started by shifting center balance all the way to the rear, then all the way to the front, and back and forth. Honestly, I think the factory speakers sounded better even though they are clearly an inferior quality product. The mids and highs on these Polk speakers simply aren't as clear as I was expecting.

Despite being less than impressed I went ahead and replaced the front speakers in the hope that I could dial things in later. I was able to make them sound a bit better though still not quite as good as the factory junk that came with the car. The stereo is kind of a budget model so maybe my expectations were a little too high.

Installation was easy and straightforward and these speakers fit more flush in the front doors of my Impreza than the rear. If you happen to have the same car know that you will have to reroute the speaker cables through the inside of both front doors and I highly recommend securing them with tie straps to the wiring harness close to where it enters the door so they don't interfere with window operation.

In the end I am neither impressed nor disappointed. I do plan on installing a subwoofer later this year, maybe that will help

Pros: Nice build quality, built-in crossovers.

Cons: Average sound.

Crutchfield Customer Review (What's this?)

I was having some trouble with a window and took the opportunity to upgrade the front speakers in my wife's 2013 Subaru Outback. The Polks are a big improvement in overall sound. As expected, they are weak in the low frequency range. I plan to add a small under seat sub to fill in the lows a little. My only regret is not doing the rears also.

Pros: nice clear sound

Cons: weak bass

Excellent speakers; easy to install

Written By GreggS, Georgia on Sunday, January 04, 2015

Crutchfield Customer Review (What's this?)

The DXi651's are excellent speakers for the price. The included mounting adapter made it possible to use the original mounting holes instead of having to re-drill. Considering I was installing the speakers in an 11 year old car that is not as water-tight as when new, the fact that the speakers are "marine certified" is a bonus. The sound quality is very good.

Pros: Flexible installation options with included mounting adaptor; marine certified; excellent value

great speakers

Written By tom, Denver, CO on Monday, November 10, 2014

Crutchfield Customer Review (What's this?)

I can't find anything about these speakers that I don't like. They do exactly what they're supposed to do, and they do it well. I've seen reviews talking about weak bass response, but those reviews were clearly left before the buyer gave the speakers a few weeks to break in. Once they break in, they will give you just as good of bass response as you can expect out of a 6.5" speaker, and maybe even a little better. I got these on sale, which made it even easier to be satisfied. Remember: every ear is different, so you need to find the speaker for you. These are slightly more bright than the Kickers I had in my last car, but more warm than the Infinity speakers I had before those, which is perfect.

Pros: solid build quality, not too warm, not too bright sound.

Cons: I wish speaker companies would start selling grills separately and charging a few bucks less for the speakers... I've NEVER used grills that come with coaxial or component speakers for my car because I use my factory locations, like everybody else.

Good Speakers Overall

Written By JP, Vermont on Monday, November 03, 2014

Crutchfield Customer Review (What's this?)

Put these in a Chevy Silverado to replace all of the 4 factory door speakers. I expected a bit more of an increase in punch and sound quality over the stock speakers, but overall they are a good sounding speaker and have improved the audio in my truck.

Pros: Easy to install, good sound overall

Cons: distortion at high volumes, not crystal clear sound, not a lot of bass punch

2014 Mazda 3

Written By Hector, Villa Park, IL on Wednesday, October 22, 2014

Crutchfield Customer Review (What's this?)

Installed these in my 2014 Mazda 3 sedan, base model. Front door speakers. OEM speakers weren't worn or old, but they definitely lacked in clarity and depth. I installed these and there is an immediate difference. Clean, crisp sound with better bass response and no distortion. At this point, it makes the rear OEM speaker's sound lacking. May have to purchase another set in the future.

With all this in mind, none of the adapters included work. Had to custom mount it to the OEM units, destroying the OEM speakers, which really wasn't a loss. I understood the risk with installing these in such a new car.

Pros: Great sound even with the OEM headunit powering these.

Cons: None.

Excellent choice for 6.5's. They sound great and for my purposes being marine ready was an added bonus. I installed these in my 84' BJ42 Toyota Land Cruiser. The car is off for months at a time so I wanted durability as well as great sound.

Wow, These speakers have rich bass, good mids, and clear highs. Perfect for my regular cab truck. I am very happy with them. After a few days of jammin they really came to life. They play everything from the Grateful Dead(Classic Folk/Rock/Jams) to Tipper(Glitch/Dub) with no issues. Don't delude yourself into thinking these will set off car alarms and you will be happy. I wonder what they will sound like amplified with a sub behind, but thats down the road, and I couldn't be happier as they are. Ordering from Crutchfield was a new experience for me, but these speakers came with the adapter harness to hook up to the stock cables (free) and instructions on installation. I must admit I am now a DXi and Crutchfield customer for the forseeable future :)

Solid speakers

Written By BA, Michigan on Monday, June 09, 2014

Crutchfield Customer Review (What's this?)

I bought these to upgrade from factory sound in a Chevy Volt (w/o Bose). Overall I am pleased. You won't be mistaken for having a powered subwoofer, but sound is full and well balanced. Bass is only moderately, but still noticeably, better than stock. This is based on running off the factory HU. An amplifier would probably be even better. Service from Crutchfield was excellent as advertised.

Pros: Clear crisp sound Decent bass Easy install

Cons: Needs lots of power for full potential

2011 Suburban Door Speaker Replacement

Written By Esteban, Chambersburg on Sunday, June 01, 2014

Crutchfield Customer Review (What's this?)

Expected better but to be fair the stock deck leaves a lot to be desired. Slight difference in bass, but still lacks depth in overall sound. I wish I had the money to invest in a better deck to run my amp and subs but it shall wait. I am very picky when it comes to quality sound so hopefully these will sound better hooked to an amp.

Pros: Fit perfect with the supplied materials, easy to install and connect.

Cons: Wish they had better sound quality with the stock deck alone.

2014 Jeep Wrangler Unlimited The sales man suggested these to me (bought in store), so I went with them. The highs are nice, compared to the stock cone speakers. But the low's on the other hand could use some work. They are ok at a low volume, but when trying to turn them up a little.... They sound like someone is thumping a 5 gallon bucket. Granted these are in the over head sound bar, the factory speakers did not do this. So, back to the drawing board for me.

Pros: Nice highs

Cons: The bass is non-existent.

This speaker set has been amazing since installation, easy installation, clear, simple fit, the tabs break off easy for ring installs, and the best part is the sound.

Pros: Easy install, great sound, clarity, well-designed, waterproof, tight sound seal to door panel and deck panel, durable, directable tweeter sound, price.

Cons: Considering that I will get a sub and amp for that sub, this con doesn't really matter for me, but the low-end bass is lacking a little, pumped up through the new head-unit and it sounds good and clear, but it's not ground-shaking, mirror bouncing, and teeth rattling.... But it will be.....

Great Speakers

Written By Lil'Yeshua, Pageland SC on Sunday, April 27, 2014

Crutchfield Customer Review (What's this?)

For my new stereo install project,I was looking for speakers that could handle low frequencies and the Polk's have a frequency range of 35-20000 hz. In my case,these Polk's eliminate my need to run 8" woofers in my front kick panels. I've bought the Polk Audio DB651's before to use in my mini SUV s sound system for mid bass fill along with a pair of 12" subwoofers. The DB651's are still functioning perfectly as I have the frequency cutoffs set right using my Blaupunkt Bremem MP76 head unit as to not send the lowest frequencies through them. I also use custom mounted A-pillar tweeters I stalled to bring the sound stage up. Whereas the DB651's have bigger magnets,the DXi651's have smaller magnets,having stiffer speaker surrounds to limit woofer excursion. I have yet to install these DXi651's but I think they'll do an admiral job.

Pros: Good sound reproduction quality and sound frequency spread

Cons: None

Bought these speakers based on recommendation from Crutchfield rep and customer reviews. I was skeptical I just got Sold speakers. Not the best simple upgrade 6.5 speakers with some bass. It was explained to me that I would loose some bass over stock, because they are paper. These sound great in the rear seat. Produce more bass than Rockford fosgate so components I have in front. Actually going to buy the Dix components and eBay the rock fords.

Pros: Great clarity. Fair price.

Not much to say here, great speaker looks like materials will last. Wish I had an amp running them but they still sound great from deck power.

Pros: Wonderful, crisp and sound awesome for the size:)

Cons: Once again this is cosmetic and 80% won't even use the grills...Square grills, under tight quarters this can be tough to get them straight on rear decks, the mount hole ends up so close to the window it is very hard to get a hole drilled and a screw mounted.

Very disappointed in these. The factory speakers in my 2013 Impala sounded much better. Very poor bass. I know you're not going to get much out of 6.5" speakers but these are not good. The 6.5" kickers I bought for my wife's Malibu were alot better. The cones on these are very stiff & just don't move enough air to generate satisfactory bass.

Pros: Good highs & midrange.

Cons: Again, poor bass response !!!!!!!

Written By Joe, Hudson, NH on Saturday, January 11, 2014

Crutchfield Customer Review (What's this?)

I purchased these Polk DXi651 to replace the speakers in the rear deck of my 2002 Honda Civic EX sedan. They fit perfectly in the rear shelf without any adapter brackets. I did have to drill 3 new holes but that wasn't difficult. This model of the Polk speakers was not recommended by the customer service reps at Crutchfield. The recommended speaker size by Crutchfield was 5 1/4" but I wanted to give these 6 1/2" a try anyway as I wanted a speaker that would provide a little more bass. These speakers have a great balanced sound and they do provide a decent bass response for my over 50 ears. I wasn't looking for the deep bass of a sub woofer just a well balanced sound and these speakers did not disappoint. This was my first purchase from Crutchfield and I am very satisfied -- they provided all the necessary accessories for the install at no extra charge and the installation instructions were very helpful.

Pros: Great balanced sound. Perfect fit in the rear shelf of a 2002 Civic

Cons: None

What an upgrade for my daughter's '99 Passat! And at a great price. I popped out the 4 stock door speakers and mounted these with ease. Matched up with a Sony MEX-BT4100P and Sound Ordnance 50W RMS amp these Polks are delivering clean crisp sound and with plenty of bass given their small size and disadvantaged mounting location. Although the bass is fine for this 50 year old, the kids love the boom so we threw in a Sound Ordnance 80W RMS powered sub in the trunk. Finally, kudos to the Crutchfield experience, all the right installation instructions and tools are always thoughtfully included.

installed all 4 speakers in the doors of my 08 Sierra. for some reason, all door speakers went out but from what I have heard, sounds common in the Sierra/Silverado. You can install these yourself, don't take to a shop. Honestly, the hardest part is getting the door panel off. the speakers sound great...I think anything would sound better than stock though! Nice base (better than stock). Supplied mounting brackets and speaker harness worked like a charm. I think total install took a couple of hours.

Improvement over OEM

Crutchfield Customer Review (What's this?)

I used these Polks to replace my original speakers in my 2008 GMC Sierra crew cab. Definite improvement over stock speakers. For a 6.5 speaker these have really good bass. They do not deliver the mid range sounds as good as I would like, even after adjusting the EQ (stock radio). I may be picky but that is my only reason for 4 stars. I saw these speakers at Best Buy for comparison, got a better deal from Crutchfield. Getting free install equipment saved me about $55 for four speakers, way to go Crutchfield!!

Pros: Full sound, good bass, FREE install equip(speaker bracket and wiring harness needed for my vehicle), plenty of mounting options, easy to install

After hearing many of the 6 1/2 speakers on this site (sony, rockford, infinity, kenwood etc) I can vouch for this polk speaker in saying it sounds pretty good hooked up to just an aftermarket radio. If you really want to hear it come to life then amp it. Overall a good sound for 75 dollars.

Pros: Good mids and decent lows and highs

Cons: Could be a little better highs and lows

Factory Speaker Upgrade

Crutchfield Customer Review (What's this?)

These speakers replaced my stock Bose front door speakers in my 2008 Chevy 2500HD. The quality is superior to the Bose speakers and the sound is more crisp.

Pros: The sound quality is great, especially for the affordable price.

Cons: none

Solid Speakers

Crutchfield Customer Review (What's this?)

I love these speakers, they really have that low range I was looking for. However I feel like it does kind of muddle the sound and I am currently running them without any extra amplification so in bass heavy songs they do kind of struggle a bit to still keep the entire sound together. But in all I would totally buy these again and recommend them highly, but I do feel these speakers were meant to be amplified.

Pros: Bass response, sound clarity.

Cons: The bass can overwhelm the speaker making the sound quality suffer noticeably. (could be more of a wattage problem on my end though so I am not entirely blaming the speaker!)

Great replacement speakers

Bought these to replace some blown factory speakers. Installation was easy and the sound quality was much improved. Great range on these. Very good speakers for the price.

Pros: Great sound & value

Good for the price.

These speakers provide good lows and highs. The midrange isn't particularly stron. But with the Helix PP50 added to the equation, the factory system rocks.

Pros: Booming bass. Crisp highs.

Cons: A little weak in the midranges. But overall, a good speaker.
