Definitive Technology SUPERCUBE-4000 Powered Subwoffer. FREE SHIPPING!
Definitive Technology SuperCube Powered Subwoofer with all-new 1200 Watt digital tracking power amplifier and quick, tight accuracy for full music enjoyment


The SuperCube 4000 features a new 8-inch (20cm) subwoofer driver pressure coupled to two 8-inch (20cm) Ultra Low Bass Radiators. The total piston area is greater than a 12-inch diameter woofer but with far greater speed, musicality and control than a single large diameter woofer could ever deliver—and it all fits in an impossibly tiny enclosure that is easy to tuck away out of sight. The SuperCube 4000 can fill most domestic spaces with loud, visceral, extended and musical bass yet it occupies less than a square foot of floor space!

Music Lovers Rejoice

  • Subwoofer manufacturers are always talking about how "explosive" their subwoofers are (frankly so do we), but there's more to home entertainment than rocket blasts and explosions—there is music, be it in the movies you watch or the CDs you enjoy. And for music the quality of a subwoofer's performance is way more important than the quantity. The bass should be "tight," precise, and musical. Bass notes should have pitch, not just a dull thud or drone
  • Definitive Technology was started by and is run by music fanatics and the very first thing we do to evaluate a subwoofer prototype design is to listen to music. If a subwoofer doesn't do an exemplary job with music reproduction, it isn't a Definitive
Digital Tracking Amplifier for Clean High Output
  • The SC4000 features a designed-from-the-ground-up brawny Class HD digital tracking amplifier that is optimized for real world power demands to deliver low distortion and high output
  • As well as producing high continuous power to cleanly reproduce sustained bass, this all-new Definitive amp has a high crest factor to deliver considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts
  • You'll enjoy high volume, high impact, and low distortion bass from your favorite action/adventure films and TV shows without sacrificing the smooth response and quick precision needed for music

High-Definition Subwoofer Drivers Deliver Superior Detail and Lightning-Fast Translent Response

  • The powerful, high-definition drivers used in the new SuperCubes were specifically engineered for their task: to deliver rock-solid low distortion bass, reaching down to the lowest frequencies, with an outstanding quality of superior transient response ("tightness")
  • The special ultra-stiff cones are joined to specially formulated surrounds and long-throw voice coils and spiders. The incredibly rigid cast Aluminum baskets are engineered to hold the massive magnet structures and large voice coils in absolute alignment
  • The high temperature voice coils are made of aluminum wound with triple insulated ultra-pure copper wire and baked in epoxy for superior power handling and reliability

Rock Solid Cabinets Ensure Pure Low Distortion Response

  • The cabinet of a loudspeaker plays a large part in its sonic performance. Resonance and vibration can add unwanted distortion as well as drain away important acoustical energy from the system. Definitive's subwoofer enclosures have been specifically engineered to be totally inert and vibration free, to ensure you of absolutely pure sonic reproduction
  • The front and rear panels are nearly 2-inches thick and the cabinet incorporates multiple internal braces to ensure total solidity. To top off the extraordinary performance, the SuperCube 4000 is finished in gorgeous piano-gloss black
