This 5.1-channel surround sound system incorporates a rear center speaker for even more realistic theater sound. The innovative Acoustimass module uses 2 downward-firing drivers to move low tones into the room on a column of air, bringing depth to the rumble of a passing train, or the resonance of a baritone's voice. The module can be hidden nearly anywhere in the room. Enjoy rich, colorful sound that appears to come only from the 5 small Direct/Reflecting speaker arrays. These arrays deliver high and midrange frequencies so you enjoy crisp, clear reproduction of dialogue and music. With Bose accessories, the arrays can be wall or ceiling mounted, placed on endtables, or on floor stands. Fully upgradeable for 6.1-channel receivers!
