The Atlantic Technology Model 3.1 HSB is a TV Speaker Base that houses passive left, center and right speakers, as well as an 80 watt powered “H-PAS-enabled” down-firing subwoofer, all in one compact sturdy cabinet 4 3/4 inches high, 36 inches wide, and 16 inches deep.

Developed to fit under any flat panel TV up to 60″ wide, placed on a credenza or entertainment stand, the 3.1 HSB is designed to be combined with a quality AV receiver. (There is no sound bar or sound base at anyprice that offers the power and flexibility of an entry level AVR.)

Pairing the 3.1 HSB H-PAS Speaker Base with an AV receiver gives the consumer a compelling home theater experience – with the option to add surround speakers – combined with a real H-PAS subwoofer that delivers room shaking bass down to 35 Hz. The AV receiver pairing allows for a simple, easy to install, great sounding system with all the flexibility of multi-zone and source switching.

The single cabinet containing the subwoofer and all three front speakers means no more hiding big black boxes in corners or behind furniture!
