The Companion® 20 Multimedia Speaker System from Bose offers natural sound whether sitting at the keyboard or across the room - without the need for a separate subwoofer. It´s ideal for anyone whose computer is the go-to device in the house for listening to favorite radio stations via Internet or enjoying games, videos or music playlists. The loudspeaker features a new driver and advanced port to reproduce music across the full frequency range. The operation is made easy with a small, circular control pod that lets users adjust volume and access one-touch muting. It also offers a headphone jack and input for an additional audio source.
