If you’re looking for bottomless bass that comes with the latest in digital technology, look no further than the SuperCube® 4000.

High Definition Drivers

Powerful, high definition drivers with ultra-stiff cones, specially formulated surrounds and long-throw voice coils are pressure-coupled to Ultra Low Bass Radiators to deliver the tightest, low-distortion bass ever.

Digitally Optimized for High Performance and Power

The all-new digital tracking amplifier is smart, powerful and more environment-friendly, delivering high-impact, low-distortion bass at all the right moments while consuming much less energy.

Computer Controlled Precision

With an integrated 56-bit Digital Signal Processor (DSP™), bass response is extended and improved. The Multiband Dynamic Range Optimizer (M-DRO) divides frequency into ranges and compresses any range that’s overloaded to prevent distortion and damage.

Rock-Solid Cabinet Enclosures

A speaker’s cabinet affects its sonic performance. Vibration drains acoustical energy and adds unwanted distortion. SuperCube® Series enclosures are totally inert and resonance-free.
