A home theater speaker system in a single cabinet that simulates surround sound. Soundbar speakers are designed for apartments or venues where discrete speakers are not desired throughout the room. Often self powered, soundbars may support a subwoofer for maximum bass response, which can be conveniently located anywhere in the room. The "virtual surround sound" from a soundbar is produced by psychoacoustic effects that adjust the timing and volume of the various speakers. Some units bounce the sound off side and back walls, which can be effective in small rooms, while others do not rely on precise placement. See home theater and home theater in a box.
Polk's SurroundBar
Designed to work with a subwoofer, Polk Audio's five-channel soundbar systems do not depend on room acoustics or critical placement in the room. Using Polk's patented Stereo Dimensional Array (SDA) technology, which stems from the late 1980s, surround sound is simulated by a combination of "acoustical engineering, psychoacoustic principles and a little magic" according to the vendor.

It's not even comparable with Zvox's previous single-speaker soundbars, the 415 ($400) and 425 ($600). Those speakers were designed to...

- If the primary appeal of soundbar speakers is based on their significant reduction of wires and clutter--as compared with 5.1-channel home theater-in-a-box systems--then Samsung's new HT-X810T soundbar should be a winner.
