The SurroundBar Smart Enough to be Called Component Home Theater.

Look at this SurroundBar, just look at it. It’s a mere 1 1/2-inches thin. And yet, it produces one of the most addicting audio experiences you are likely to experience in a single-speaker system. How can this be? To reach this level of high performance, Polk  engineers made a tactical design decision to separate the SurroundBar 500 CHT’s crossover and proprietary digital audio technologies into a separate rack-mountable black box: the external SDA® control module. The compact SDA control module goes right where your audio equipment or cable box goes, connects in seconds with no setup at all, and ensures an audio experience just not possible from other soundbar designs. The impossibly thin SurroundBar 500 CHT delivers a surprisingly wide, deep, detailed and realistic front soundstage for any application, and effortlessly adds excitement to your TV viewing, movie watching, and gaming.

SurroundBar 500 CHT Features:

An incredible 12-driver array, including nine ultra-shallow ASP aluminum dome mid-woofers and three 3/4-inch high performance ring radiator tweeters, in a mere 1 1/2-inch of depth.

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.

Polk Digital Logic® technology, a proprietary DSP program, automatically calibrates and optimizes your SurroundBar for any room shape or system setup.

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 between the control module, your TV, and your source components, with no complex setup or calibration needed. It works right out of the box!

Control module has receiver inputs, channel mode switch and output to the SurroundBar.

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.
