Your ride. Our Sound.

Like the other subs in the DXi Series, you’ll find all the features that make DXi totally performance driven.

DXi104DVC 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.

Polymer woofer cones and butyl rubber surrounds will not break down over time and will survive the rigors of harsh automotive environments.

High temperature copper voice coil (50db) and polyamide former stands up to the most rigorous use while maintaining extremely low distortion for bass punch and output.

Heavy duty input terminals accommodate speaker wire up to 8 AWG or twisted pairs of 12 AWG.

Advanced carbon composite basket based on the spokes of a wheel is lightweight, will not flex during peaks and looks great!

Single voice coil configuration (DXi104) also available.

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.
