The Definitive Technology SuperCube is a high-quality powered subwoofer designed for music and home theater systems. It features a bass-reflex passive radiator enclosure with a 10-inch long-throw woofer pressure-coupled to two 10-inch ultra low bass radiators, providing a total piston area equivalent to an 18-inch woofer but with greater speed, musicality, and control. The subwoofer is powered by a 1500-watt RMS class D amplifier utilizing Definitive's proprietary PowerField technology for optimum load matching and power transfer, delivering high-definition bass down to 13 Hz with low distortion and superior transient response. It includes continuously variable low-pass and high-pass crossovers, phase control dial, speaker-level and line-level inputs and outputs, and an LFE input for home theater integration. The enclosure is finished in piano-gloss black and measures approximately 14-5/16" W x 14-3/4" H x 15-7/16" D, weighing 70 lbs. It comes with a 5-year warranty on the woofer and 3 years on the amplifier.
