Our premium computer speakers deliver multichannel sound that seems to surround you, specifically designed for computer listening. Just right for music, games and movies-and setup is a snap. The Companion(R) 5 multimedia speaker system is engineered to deliver the excitement of surround sound content right at your computer-without the clutter of five speakers. Just two small speakers and a hideaway Acoustimass(R) module deliver much of the audio performance you'd expect from a five-speaker surround sound system. And a single USB connection is all it takes-no special software, hardware or sound card upgrade necessary.* The system features a handy, all-in-one control pod to keep speaker volume control, single-touch mute, headphone jack and an auxiliary input all within easy reach. Speakers are mounted on stands enabling superb performance and more usable desktop space. *For optimum performance, we recommend Windows XP or later. For Macintosh computers, OS X 10.4.6 or later.
