Our take on the Definitive Technology SuperCube IIIby Crutchfield's Kristen Schaub

Ultra-compact subwoofer delivers big bass

Definitive's smallest subwoofer, the SuperCube III provides huge bass performance in a compact, room-friendly enclosure that takes up less than a cubic foot of floor-space. The secret to its success is an active woofer/passive radiator combination that produces big sound despite the cabinet's small size. And a powerful built-in 650-watt amplifier really shows off this little sub's tight, accurate bass response.

A unique approach to rock-solid bass 

A look at the rear panel offering a number of hookup options.

The SuperCube III contains a 7-1/2" woofer pressure-coupled to two 7-1/2" passive radiators, for a total output around that of a traditional 12" woofer. This driver array gives the SuperCube III the advantage of far greater speed, musicality, and control than any large single-woofer sub could produce. The woofer is encased in an incredibly rigid basket engineered to hold the massive magnet structure and large voice coil in absolute alignment. The non-resonant cabinet is nearly 2" thick and uses multiple internal bracings to make sure that you hear clean bass without sound-muddying vibrations.

Flexible inputs and outputs and advanced controls

Line-level and speaker-level inputs let you connect this sub to just about any audio system. The continuously variable low-pass crossover allows you to precisely control the frequencies that your subwoofer handles. And the built-in high-pass crossover is a nice touch: it prevents your main speakers from overloading with low frequencies if you hook them up through the subwoofer's speaker-level outputs.
