Your Ride. Our Sound.

By separating the driver and tweeter, you enjoy better mid-range performance with the 4x6-inch plate. Its plate configuration affords easy mounting in a front dash or other existing factory locations. If you want a DXi loudspeaker that’s a quick, easy install, the DXi460p is your speaker.

DXi460p 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

3/4-inch silk dome tweeter delivers clear, well-defined highs.

Durable butyl rubber surround won’t fall apart under the stress of extreme temperatures, sunlight or time, for years of great Polk sound.

Polymer/mica composite cones are stiff yet lightweight for big sound, small distortion.

Low-mass 2-layer Kapton voice coil-Kapton’s high melting temperature (725°F/400°C) ensures high power handling and kick-butt reliability.

Pole plate heat sink promotes better heat dissipation for superior power handling and reliability.

Marine Certified to withstand the harshest environments on the water (hey, maybe you have a truck you tow a boat with).

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.
