The Definitive Technology SuperCube 4000 brings theater-like bass performance to an enclosure the size of a breadbasket. A compact 11 x 11-7/8 x 12-1/2-inches unit houses the 1,200-watts of 2-way subwoofer power. An 8-inch active driver combines with two 8-inch passive radiators to give the Definitive Technology SuperCube 4000 more piston area and musical responsiveness than a larger enclosure housing a single 12-inch speaker. The Definitive Technology SuperCube 4000's speaker configuration, powerful amplifier and rugged construction are combined to give this Definitive Technology subwoofer a frequency response range of 16 Hz to 200 Hz. Listeners can also use the wireless remote and digital readout to program the 2-way subwoofer to set parameters like equalization, phase control and crossover frequencies to values appropriate for the sound system, the room and environment from wherever they are located. This Definitive Technology subwoofer combines house-rocking power with durability and technological sophistication to handle both the explosions of a summer blockbuster and the subtleties of an acoustic bass with ease.
