The Raptor System III is easily the highest output, widest bandwidth plug-and-play, music and home theater subwoofer system ever offered in a single package system. Raptor System III 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 III consists of four 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. Again, because it's worthy of repetition, that's 8-proprietary BHT-15 long throw drivers, capable of a staggering 40 liters of displacement driven by 14000 peak watts with 9 user-selectable native frequency responses.

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 per module or per stack. 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.
