Precision woofers showcase your music
The DXi525 speakers feature 5-1/4" polymer/mica 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 dome tweeters broadcast sweet sound
Rest assured, you'll hear every detail of your most enthralling musical moments. Each 3/4" silk/polymer dome tweeter brings out the high-frequency highlights in your music, and a proprietary magnetic liquid cools each tweeter so you'll get clear sound and excellent long-term performance. From an intensely quiet acoustic pluck to the most exhilarating electric solo, it'll be a very entertaining ride.

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 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 Polk DXi 525 speaker features a Dynamic Balance, polymer/mica composite cone woofer. These composite cones feature tremendous stiffness-to mass ratio. Lower mass means faster transients and finer detail.

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

Silk Dome Tweeters: Each Polk DXi 525 speaker features a 3/4" silk dome tweeter for clear, accurate highs. They can be angled slightly within the housing to compensate for off axis mounting. The tweeters also employ a light-weight neodymium magnet for higher efficiency.

Mounting: The Polk Audio DXi 525 speakers fit in a standard 5-1/4" opening (typically 4.3" to 4.8" cutout) with four mounting holes.

I am considering the purchase of these Polks, I have Kenwoods in the door panels at this time. Does anyone have any experence with these speakers working well together?

These speakers will work well with anything you plan to use. I have used Polk for many years and i am very happy with the results and have been like i said for years. I currently have them in my doors as well, and have 4.5's in the dash and some kenwoods(6X9) in the back. Great set of speakers, highly recommended.

I think they'll be fine, need an amp to really make these polk's come alive

I'm not sure of the Kenwoods, you'd probably want to compare specs and see if they are close. I have my Polk's mounted in front doors and a pair of Infinity Ref 6032si speakers in the rear seat panels. These two pairs complement each other well. I would just compare the actual specs of the two sets and if they are close they should work ok together.

Hello Kevin, I have been in the car audio installation side business since 1995 and I have purchased a lot of items from Crutchfield actually over $8,000.00 worth. It would depend on what grade of Kenwood speakers you have, but between Kenwood and Polk I personally would go with Polk and I have purchased and installed the speakers you are asking about in a 95 Jeep Cherokee Sport which is connected to a Kenwood cd/usb receiver and they sound great. Also I have an amp and a sub for the low frequencies in the 95 Jeep Cherokee. I hope this helps, M. Fletcher
