Definitive Technology SuperCube Reference Powered Subwoofer

Earth-Shattering Bass. Microscopic Footprint.

Don’t let the compact dimensions fool you. The Definitive Technology SuperCube Reference is a masterclass in acoustic engineering, designed for the absolute bass purist. Whether you are building a world-class home theater or demands flawless, pitch-perfect low-end extension for a high-fidelity audiophile setup, this legendary subwoofer delivers foundation-shaking power without taking over your living space.

By pressure-coupling a massive active driver to dual infrasonic passive radiators, the SuperCube Reference delivers the raw air-moving power of a traditional 18-inch woofer, but with the lightning-fast transient response and tight control that only a smaller, finely-tuned system can achieve.

Key Performance Features

1,800 Watts of Pure Class D Muscle

At the heart of the SuperCube Reference is a monumentally powerful 1,800-watt Class D digital amplifier. This massive power reserve ensures the subwoofer never runs out of breath, delivering clean, distortion-free bass even during the most demanding cinematic explosions or complex musical passages.

Triple-Driver Architecture

Instead of relying on one slow, oversized woofer, the SuperCube Reference utilizes a sophisticated three-driver array:

  • One 14” High-Definition Long-Throw Active Driver: Hand-built with a rigid cast-aluminum basket and a massive magnet structure to stay perfectly aligned under extreme excursion.

  • Two 14” Infrasonic Passive Radiators: Pressure-coupled to the active driver to dramatically amplify total bass output down to a subterranean 11 Hz—well below the threshold of human hearing and deep into the realm of pure feeling.

Definitive "Sock-Style" Resonance Control

The non-resonant cabinet features internal bracing nearly 2 inches thick to eliminate sound-muddying panel vibrations. Wrapped beautifully in Definitive Technology’s signature black mesh grille cloth and capped with stunning piano-gloss black endplates, it blends seamlessly into any room decor.

Precision Tuning & Connectivity

The comprehensive rear control panel puts total optimization at your fingertips, allowing you to perfectly blend the subwoofer with any main tower or bookshelf speakers:

  • Continuously variable low-pass filter (40Hz–150Hz)

  • Continuously variable high-pass filter (40Hz–150Hz) for line-level outputs

  • Unfiltered LFE Direct Input for seamless home theater receiver integration

  • 0 to 180-degree variable phase adjustment dial

Why Audiophiles Choose the SuperCube Reference: Most high-output subwoofers sound "slow" or boomy when paired with delicate acoustic music. Because of its pressure-coupled configuration, the SuperCube Reference possesses the speed and musicality required to seamlessly mate with everything from high-end floorstanding towers to electrostatic speakers, all while maintaining the capacity to rattle your windows when a movie demands it.
