Keeping it Simple, Keeping it Real

Thin, but only in size, never in performance. Just 2 1/2-inches deep! Inside the sleek enclosure sit ten specially engineered Dynamic Balance® drivers. Seven 2 3/4-inch composite mid-woofers, designed for high performance in a shallow-space enclosure, feature powerful neodymium magnets ensure smooth frequency response throughout a wider soundstage. Three 3/4-inch high performance silk polymer dome tweeters ensure realistic imaging and superior detail whether you watch TV, movies, or games. SDA® technology allows this single-speaker driver array to deliver an awesomely spacious and realistic soundstage in any room setup.

SurroundBar 400 CHT Features:

Polk's patented SDA surround technology delivers a rich, enveloping listening experience from a single source; no rear speakers or special room characteristics are required.

7CH, 5CH or LCR configurable all from a single switch.

Installs anywhere easily, with the simple secure wall-mount bracket or shelf cradle.

Extruded aluminum enclosure is designed to eliminate performance-robbing cabinet resonances.

Anti-diffraction grille and bezel design create surprisingly open, spacious imaging.

Easy plug-and-play connections, and no complex setup or calibration needed. It works right out of the box!

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.
