The SuperCube II is more particularly a compact, 1250 watt sub-woofer meant to be used with related DT series units. The SuperCube II cabinet stands 12-1/2" tall and measures a total of 1 cubic foot; it is surrounded in a professional finish that is available in a glossy Piano-Black color. Each SuperCube II sub unit includes one high-definition 8" long throw woofer, pressure coupled to two 8” low bass radiators. Definitive Technology claims that the SuperCube II sub-woofer includes high definition sound drivers that "were specifically engineered for their task: to deliver rock-solid low distortion bass, reaching down to the lowest frequencies, with an outstanding quality of superior transient response".
The SuperCube II sub-woofer includes additional features such as a set of rubber feet and isolation spikes to keep the unit grounded during playback, an auto on/off feature with signal sensing capabilities, high definition sound support, two pairs of 5 way binding post inputs and outputs (high level), one LFE input (SW preout only), and a DT 5 year warranty for the unit/ 3 year warranty for the internal amplifier.
