Definitive's elegant and ultra-compact SuperCube subwoofers deliver ultimate bass performance from beautiful enclosures that fit anywhere. They combine Definitive — designed, digitally coupled (patent pending) Class D digital switching amplifiers with extremely long-throw, huge magnet, front mounted subwoofer drivers which are tightly coupled to dual side-mounted, pressure driven infrasonic bass radiators. The SuperCubes deliver incredibly deep, high-impact low-frequency performance with superbly tuneful high-definition transient response for bass that sounds as good with delicate music as with earth-shaking action movies. Both include complete input, output, level control, continuously variable high-pass and low-pass crossover facilities plus a continuously variable phase control and direct-in LFE input. These remarkably compact superwoofers feature Definitive's signature piano-gloss black end caps and wraparound grille cloth styling.
