If you're looking for the most engaging computer audio experience from Bose, these are the speakers you want. The Companion 50 system immerses you in a dramatic acoustic environment you might expect only from a five-speaker system. Yet it all comes from just two elegant desktop speakers and a hideaway Acoustimass module. More and more, you're using your computer for all kinds of entertainment. Music. Films and TV programmes. Gaming. But if you're still using your laptop speakers, or the ones that came with your desktop, you're not coming close to the audio experience that you should be getting. The Companion 50 system provides a welcome change. It uses proprietary TrueSpace® digital processing circuitry to deliver a wide, spacious soundstage, reproducing the original dramatic intent behind the music, films and games you enjoy.Features Rich, detailed sound with a wide soundstage immerses you in the experience Deep, accurate bass from the Acoustimass module, which you can hide under a desk All-in-one control pod houses volume control, single-touch mute, headphone jack and auxiliary input Single connection to your computer - no sound cards or software upgrades needed Energy-saving sleep mode engages after 30 minutes of inactivitySpecs Dimensions Each satellite speaker:21.90 cm H x 13.90 cm W x 9.10 cm D (0.70 kg) Acoustimass module:21.80 cm H x 17.30 cm W x 34.80 cm D (4.60 kg) Control pod:6.35 cm H x 2.86 cm W System in box:28.30 cm H x 40.50 cm W x 43.50 cm D (7.92 kg)
