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 DXi691 speakers feature 6"x9" 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.

Silk/polymer and aluminum dome tweeters broadcast sweet sound

Rest assured, you'll hear every detail of your most enthralling musical moments. The 1" silk/polymer dome tweeter brings out the high-frequency highlights in your music, while a 3/4" aluminum dome supertweeter adds breathtaking dimension. From an intensely quiet acoustic pluck to the most exhilarating electric solo, it'll be a very entertaining ride.

Product Highlights:

  • 6"x9" 3-way car speakers (pair)
  • polymer composite woofer with butyl rubber surround
  • 1" liquid-cooled silk/polymer composite dome tweeter
  • 3/4" aluminum dome supertweeter
  • power range: 2-100 watts RMS (300 watts peak power)
  • frequency response: 35-22,000 Hz
  • sensitivity: 93 dB
  • top-mount depth: 3-1/4"
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Features

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.

Tweeters: The DXi 691s feature a 1" silk/polymer dome tweeter and a 3/4" aluminum dome super tweeter for clear, accurate highs. The tweeters employ light-weight neodymium magnets for higher efficiency.

Polk Audio DXi691 6x93-way speaker

Written By John, Arlington, Washington on Wednesday, December 17, 2014

Crutchfield Customer Review (What's this?)

Easy to install front door speakers for Ram 3500 Quad Cab. Initial audio quality is exponentially better than stock. Very bright sound and ample bass with stock radio.

Pros: Very simple install. Great sound even with stock radio.

Cons: None

6 x 9, oh so fine!

Written By Happy = Car + Awesome Sounding Music, Sandy Hook, CT on Thursday, December 11, 2014

Crutchfield Customer Review (What's this?)

I was commissioned by a friend to revamp his 05 Malibu's sound system. Good move, sir. Because rule #1. Every factory sound system needs replacing (sorry BOSE, that means you too! I have to say I'm a bigger fan of your marketing techniques than your sound). That being said, I'm not the type of person who wants to see how much bass can I fit into my car before the windshield gasket fails, but I like to configure any car with a system that sounds most accurate. There's a big word for everyone to stop under-appreciating. I like giving every frequency in songs I hear their own respected space, or at least a fair chance! And getting loud doesn't hurt, but it's not my primary objective. The Polk Audio DXi691 fit inline with my goal. They give some good punch in the low-mid to mid range and sound clean and crisp in the mid-high to high range. Low end is lacking, but that's what subwoofers are for, people! It also fell within budget for the build. So really, I have nothing to complain about except for the fact that auto manufacturers are still producing cars with 6 x 9 drivers in the first place, but that's a different rant for a different day...

Pros: These things look sweet and cover a huge range of frequencies. I love polk...

Cons: 6 x 9 speakers are like the awkward kid at the dance. Nobody really invited them, but they're always going to be there...

Great sound and quality

Written By J, Charleston on Saturday, September 06, 2014

Crutchfield Customer Review (What's this?)

Sound is clear and bass works much better than my stock speakers. If Crutchfield recommends you to purchase a mounting bracket, make sure you look for one online because it'll save a lot of headaches trying to make them fit.

Pros: Easy to install Great sound quality

Cons: Didn't fit my car perfectly so I had to purchase mounting bracket. Not much of a con but would've been nice if Crutchfield also sent me the bracket so I wouldn't have to spend time looking for one.

DXi691 Review

Written By Macpin, Honolulu, HI on Friday, July 25, 2014

Crutchfield Customer Review (What's this?)

The Polk Audio DXi691 is an excellent marine certified set of car audio speakers. Living on an island warrants the need to have this amount of resilience to the environment. The DXi691 speakers are very crisp in the highs and solid in the mid bass frequencies. To get the most out of these speakers, I strongly recommend a head unit with more than 3 integrated digital equalizers. The DXi691's 3-way setup will sound brighter and more dynamic. Its lowest frequency is rated at 35Hz which I heard after the break-in period. I mounted them in properly soundproofed doors of my Dodge Ram 1500 Quad Cab. It takes a lot to reach 35Hz so I recommend adding an enclosed marine certified subwoofer to achieve the lower bas frequencies. The DXi691 speakers are a great replacement of factory speakers. The sensitivity rating is over 90 dB which means you really need to have those equalizers to better tune to your liking.

Pros: Great sound and frequency range for highs and mid bass.

Cons: Head unit needs to have an equalizer with more than 3 bands to better tune to your liking. Recommend adding an enclosed subwoofer to cover the lower bas frequencies.

Good Sound

Written By Green, Asheville, NC on Sunday, June 29, 2014

Crutchfield Customer Review (What's this?)

Sounds great, but really require an amplifier if installing with a factory or even aftermarket head unit as the system will sound underpowered. After I installed an amp, the sound from the DXi691s is clear, balanced and plenty loud. Definitely worth the investment, but make sure to save some money for an amp if you're replacing a factory system

Pros: Great high and mids, bass is adequate, plenty of volume

I used these in a homemade soundboard I built for my jeep TJ. They were a perfect fit for this application...and look awesome as well... Very happy with these!

Cons: Don't have anything negative to say about them.

Written By MiLo, Chicago, IL on Monday, March 10, 2014

Crutchfield Customer Review (What's this?)

(1st off let me just say, If you're looking for bass that will blow your ear drums out go buy an Amp and some Subs. These will not do it all by themselves.) - Testing for review. Bought these in the beginning of Feb, its now Mid March. Doing great so far. I Think I broke them in enough already. In my '04 Olds Alero I was looking to upgrade from stock speakers because mine blew out a couple months ago. I was doing the shop-around for quite some time. Then I found these. These 3-ways are phenomenal for the price at Crutchfield. These are a really great choice because of the clarity at any volume. Mind you, I've only tried these with my aftermarket stereo system (JVC KWHDR720). These bring the highs in nicely (you can hear things that you never heard before), the mids are solid (the clarity doesn't get better than these) and the lows are great (considering I don't have subs), if you have and equalizer like I do then you can definitely make these sound the way you want them to. I still get people looking my way. You don't know what you're missing until you get a nice 3-way. ***** Must get the DXi461p***** compliments these well

Pros: - with the provided harness, these are a breeze to install. no cutting/stripping wires, no soldering. Just unclip stock speakers, attach harness and clip on the new speakers. BOOM! - perfect fit, no need for modification - no subs, no rattling, no problem. - nice clean all around sound

Cons: In "my car" it's a PITA to get at the rear deck other than that I CAN'T THINK OF ANY!!!! LEARNED FROM EXPERIENCE, don't raise the volume up all the way until you break in new speakers for a couple weeks (especially if you live in the bitter cold ***northern/midwest states***) you will blow your nice brand new speakers

Crutchfield Customer Review (What's this?)

These are some of the best sounding speakers I have ever installed. Great frequency response and very clear. I am also amazed at the price. Be sure to pair this with an amp. I paired it with Alpine MRP-F300 bridged, and couldn't be happier. I have not listened to them without the amp so I cannot comment on that.

Written By JeffK, Grand Rapids, MI on Tuesday, December 03, 2013

Crutchfield Customer Review (What's this?)

I purchased these for my son's car, just turned 16, and they are worth every penny. They are hooked up to an after market Kenwood radio and a 125W x 2 pioneer amp ($200/$100...nothing real high end). The sound is crisp and the speakers are capable of handling any type of music. If you are looking for low, booming base then these are not for you, but if you want great sound, clarity and hard hitting base....perfect speaker. My son listens to Dubstep and he loves these speakers. Honestly, I can handle listening to dubstep through these as well. Crutchfield advisors were dead on in recommending our set up.

Pros: Crisp, distinct sound. Sound great at any volume level

Cons: None that I can think of

I installed these in the front doors of my 2006 Ram2500. Fit nicely with the provided spacers. Very nice sound. Really surprising when compared side by side with the stock ones, both looks and sound. The hide behind the factory door panels and everything looks stock and clean. I am running the Alpine KTP-445 amp and it really woke them up!

Pros: Good bass, good fit, nice sound overall.

Cons: None really.

Polk Audio DXi691 6x9's

Written By Jay, Albuquerque, NM on Saturday, August 03, 2013

Crutchfield Customer Review (What's this?)

I wanted to replace the stock front door speakers in my 2006 2500 Dodge Ram Mega Cab. These were recommended as a good fit from Crutchfield. I was torn between component's and these. I haven't had 6x9's since I was a kid, so I was a bit skeptical. But I am really impressed with these speakers. The install was straight forward. But they do fit a little awkward in the doors. The magnet is so much larger than stock I was afraid it would hit the glass but it does fit without issue. Once installed and door panels back on cranked it up. The sounds was far better than stock. Much better sounding high's and mid's. The bass from them is also ok, but we all know 6x9's aren't pass monsters. But overall these speakers to an excellent job with all the music I listen to from metal, rock and roll to an occasional rap venture. I would definitely recommend.

Pros: Great high's and mid's.

Cons: Bass is lacking but they are 6x9's

So far, so good

Crutchfield Customer Review (What's this?)

I pulled the engine of my car so during the down time I replaced the 33 year old speakers. (it was time, trust me) The new ones sound great but sitting in the garage with the battery charger hooked up is not a proper test. The real test will be if they can be heard while I'm at the strip drag racing,,,,,,,
