Polk Audio DXi691: Clean and Precise Sound




Klippel Motor Optimization:

The DXi691 is made with laser measurement technology via the Klippel Motor Optimization for a smooth excursion path at any volume. This creates a more efficient and long lasting speaker that performs great at low or high volumes. This model is equivalent to the popular db691.



Proprietary Dynamic Balance Technology:

Polk's engineers are able to design out driver and system resonances that cause distortion with the Dynamic Balance technology. The composite cones also feature a stiffness-to-mass ratio that allows the speakers to react to faster transients with finer detail. You not only get clarity, but function and precision.



What does Marine Certified mean?

The DXi Series speakers go through the ASTM (American Society for Testing and Materials) marine testing to become marine certified. The speakers go through two harsh tests: the B117-03 Standard Practice for Operating Salt Spray (Fog) Apparatus and the D4329-99 Standard Practice for Fluorescent UV Exposure of Plastics. The Salt Fog tests exposes the components 95° Fahrenheit and 5% salt solution for 500 hours and the UV test puts the speakers through 8 hours of UV-B light, black body temperature of 60 degrees Celsius and 4 hours condensate water, black body temperature of 40 degrees Celsius. These tests ensure these speakers will last in the harshest of marine environments.

Great product

I bought this to run in the rear of my 2009 Chrysler 300 to back up my Polk MM6501 set in the front. Running them off of a pioneer GM-D8604 100watts rms x4. They sound great, the difference is noticeable, but they aren't that bad compared to my MM6501's and for the sale price of 69.99, I wouldn't hesitate to do all 4 speaker locations with these if I was on a budget. These speakers are an amazing value at $70. I would even pay $110 for these.

Great boat speaker, especially for the price

Just refinished the entire interior of my 21' jet boat, to include the stereo. I'm running 4 DXI691s, a small JL Audio amp, and a Clarion head unit. The system sounds great and it didn't cost too much. Everyone who had heard it has commented about how good it sounds, and loud. Would buy these speakers again without hesitation.

Great speakers for the price

I previously had these and accidently blew all four not thinking correctly while hooking up amplifiers for them.. I bought my second pair here and finally got them running with proper power and tunes decently. They get loud with maintaining pretty good SQ. They also take bass slamming at 141db very well from the trunk

WOW - Just WOW

I was getting some clipping on the JBLs so decided to upgrade to these Polk DXi 691s. I use them with a Rockford Fosgate Punch 300x2 Amp for an old C3 Corvette Stingray. These speakers are incredible. So much more base than the JBLs that were in their and they sound incredible. Excellent value.

Good speakers But......

they did not fit like they claim, these speakers can fit the car. I know I made them fit. but with some thinking and some work. any standard speaker can fit, but the Toyota mounts and screw holes are setup different, I used some washers to hold the speakers after drilling some holes in the back dash
I may put the video I took of them installed on youtube

Work great.

Just put these in my '06 Dodge 2500 as a replacement for the OEM speaker that went out. These are a definite upgrade, they are much deeper and do require the spacer ring between the speaker and door. (or you will need to cut the door) They do fit but wouldn't go much thicker between the door and panel. ( unless you want to put the grills on). Highly recommend the quick wire attachment kit as it does make it plug in play without any fuss. I did get the panel remover kit in which I only needed the skinny bar to pop the window control plate (which was worth it) All in all easy, easy, pumpkin squeeze
