DXi104 10-inch subwoofer makes it easy to add bass to any audio system, and do it with more style, more performance and at a price that won’t blow your audio budget. Here’s how the DXi104 delivers its big bass performance.

DXi104 Features:

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

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 withstand 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!

Klippel optimized components for the best possible performance, even at extreme listening levels.

Dual voice coil configuration (DXi104DVC) 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.
