Five-speaker systems are great for home theater, but theyre not so sensible for your laptop or PC entertainment. Thats why we developed Companion 5 speakers. Theyre designed for 5.1-encoded music, games and movies, using just two desktop speakers and a hideaway Acoustimass module . Youll hear multi-channel sound in a way that seems to surround you; without the clutter of five speakers. And setup is easy, with a single USB connection to your computer.
