Five Channels. One Speaker. Zero Clutter.

This is the original SurroundBar, the one that raised the bar on “sound bar” speakers using exclusive, patented Polk Audio technologies. It uses a carefully engineered array of seven 3-inch Dynamic Balance® drivers, and three 3/4-inch high performance dome tweeters, to deliver clear, natural midrange, blended realistically with detailed highs. The addition of Polk’s SDA Digital Surround Technology allows this speakers to work well in any room setup, with no complex calibrations, unlike most other sound bar speakers. Only SurroundBar delivers this kind of spacious, enveloping surround-sound, with lifelike imaging.
