Our take on the Polk Audio DXi571

by John Pollard
Polk Audio

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.

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 DXi571 speakers feature 5"x7" 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.

  • 2-way car speakers (pair) for 5"x7" and 6"x8" openings

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.

Aluminum Dome Tweeters: Each speaker features a 3/4" aluminum dome tweeter for clear, accurate highs.

Speakers are very respcetable

Written By Noid 1037, Tulsa, OK on Monday, February 10, 2014
Crutchfield Customer Review (What's this?)
 
I purchased these speakers for a 2012 Ford F-150 XLT Supercrew. They were installed on the front doors. The factory passenger side speaker had stopped working-blown! They went right and no problems getting them installed. They sound better for sure than the Ford factory and I am likely going to replace the rear door speakers in the very near future!
Pros:
Easy connection, same size as the factory - no mods needed. Nice sound and nice look.
Cons:
not much

Written By Anonymous, Powell, WY on Monday, December 02, 2013
Crutchfield Customer Review (What's this?)
 
To be honest, I did not like them at all to begin with as they were quieter and less bass than the stock unit. Figured out that the baffle was killing them, I was not aware that the baffle needed to be cut out. After reading some posts about them, I ended up removing the baffle and now they sound much, much better. Was hoping for a bit more bass, but great clarity, so overall, happy with them now.
Pros:
Very good clarity.
Cons:
Could have a little better bass.

polk speakers

Written By Anonymous, Cranston ri on Friday, September 13, 2013
Crutchfield Customer Review (What's this?)
 
These speakers sound way better than stock but they crack and distort a bit. I like it loud in my car and so far to keep the speakers from cracking I haven't been able to put them as loud as I'd like and I have to keep the bass at zero along with mid's and tremble. I have these in the rear of my mustang.
Pros:
Better than stock
Cons:
Crack and distort with any bass at all

Great Sound Mid Level Speaker

Written By B, South Florida on Saturday, August 31, 2013
Crutchfield Customer Review (What's this?)
 
Great sound for what I would consider a mid level speaker. Covers a wider range of sound than most speakers in the same price range. I bought 4 for all the doors and as of now have them hooked to a factory head unit and its already a noticeable step up. As soon as I get a new head unit I know they will be even more refined.
Pros:
Price, wide range of sound. Easy to install in factory openings.
Cons:
If you are looking for a high end speaker look at a different model but this is more than suitable for a mid level Or factory upgrade.

These speakers hit well on the bassline and are decently priced. i would recommend these to someone who wants a nice pair for a decent price. Although the tweeters are not the best.
Pros:
Bass sounds great Decently Priced
Cons:
Tweeters could use some upgrading

Very hard on the ears

Written By msw1, Glendale, Az on Sunday, July 14, 2013
Crutchfield Customer Review (What's this?)
 
Purchased these for a 1999 Ford Expedition. The fit was perfect front and rear. They have a decent amount of bass for their size. Unfortunately, the tweeters on these speakers are awful. My adviser did tell me they were bright, but that is not the appropriate description for these. They are extremely harsh and gave both my wife and myself headaches after listening to them. My ears physically hurt after just 10-15 minutes at a moderate volume. I strongly do not recommend these speakers unless you enjoy an extremely bright, irritating tweeter.
Pros:
Perfect fit. Decent bass.
Cons:
The harshest tweeters I have ever experienced.
