Bose knows a lot about cramming a lot of technology into a compact product. Look at the Companion 20, the set Bose calls its "best two-piece system". You wouldn't think two medium-sized speakers could properly fill a room, but you'd be wrong. The Companion 20, equipped Bose's advanced port design, are able to produce the spot-on, natural sound recreation that we've come to expect from the legendary company.
