Your Ride. Our Sound.

That rear deck is aching for thunderous loudspeakers like the DXi690 6x9-inch 3-way loudspeakers, featuring both a 25mm liquid-cooled dome tweeter and a 19mm super tweeter. Want more performance but don’t want to go the component route? Choose the DXi690 3-way. You get a woofer and tweeter, plus a dedicated midrange driver for the absolutely crucial mid-frequencies. That extra mid-range energy can create more uniform sound overall.

DXi690 Features:

Dynamic Balance® driver technology for pure, distortion free sound.

Composite cones feature excellent stiffness-to mass ratio. The cone’s low mass produces fast transients and good detail.

Klippel optimized components for consistent, distortion-free sound.

Marine Certified means the DXi690 is built tough to withstand the harshest environments on the water.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
