The Acoustimass 10 Series V home theater speaker system delivers spacious 5.1 surround sound. The small Direct/Reflecting Series II speakers have been redesigned with a slimmer profile and can be mounted flush to the wall, so they better match flat-panel TVs. The Acoustimass module is the best-performing Acoustimass module from Bose, delivering the loudest, deepest bass - and it can be hidden out of sight behind a couch or curtain. Together, they bring Bose performance to TV, sports, movies, video games and music. You'll enjoy all your entertainment more, every day. Pair the speakers with your choice of A/V receiver, and you'll experience theater-like sound with powerful bass. The Acoustimass module has adjustable controls for volume and low-frequency effects. The system includes cables and connectors that are clearly marked for easy installation and setup.
