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.

Easy install and instructions. Great sound. Will buy another set for my other vehicle

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.
