The Raptor System II utilizes the only 2 x 15" dual opposed driver subwoofer modules that feature an up-firing/down-firing configuration ever offered commercially. The advantages of a subwoofer that's configured this way are explained in detail on our website Q&A page.

The Raptor System I consists of two Raptor Modules, each module loaded with two BHT-15 long throw proprietary subwoofer drivers, the SEQSS analog signal shaper and the all-new A-14K amplifier. With 9 selectable curves, it's truly like having 9 subwoofers systems in one, eliminating the costly experimentation involved in trying many different systems until you find the one you prefer.

Your Home Theater space will be immediately enhanced by the addition of the Raptor's impeccable craftsmanship and unique high-tech design. Specifically designed to fit snugly into a corner for optimal performance in a tiny footprint of less than 3 square feet. The System is also designed to be stacked for even more space-saving and power concentration. And, with the SEQSS taking up only i rack space and the A-14K amplifier taking up only 2RU of your hardware rack and weighing in at a mere 36 pounds, Raptor is as easy to integrate as it is to look at.
