Atlantic Technology 3.1HSB H-PAS Speaker Base

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 any price 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 options to add optional "real" surround speakers - combined with a real H-PAS subwoofer that delivers room shaking bass down to 35 Hz.


"I’ve never heard this kind of low-frequency extension in a soundbase (or standalone soundbar, for that matter). In fact, the 3.1 HSB plays way lower than any monitor I’ve heard without subwoofer reinforcement, and it might even embarrass a so-so mass-market floorstander." -Sound & Vision
