Your Ride. Our Sound.

Turn up your vehicle’s audio performance with the DXi650, a 6 1/2-inch coaxial speaker designed to drop into a variety of applications in no time at all. Advanced materials reduce component weight while offering rock solid reliability, advanced looks and ultra-high performance.

DXi650 Features:

Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.

Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

The DXi650 comes with 6 3/4-inch adaptor rings for easy fit in VWs, Audis, BMWs and other European cars.

Polymer/mica composite cones are stiff yet lightweight for big sound and little distortion.

Marine Certified means the DXi650 is built tough to withstand the harshest environments on the water.

Low-mass 2-layer Kapton voice coil has a high melting temperature, ensuring reliability and high power handling.

Swivel mount tweeter allows precise aiming of sound.

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.
