Huge Bass from a Tiny Enclosure.

If you want all the high impact bass excitement of the finest home theater audio systems without consuming a large amount of floor-space, and if you want the latest features and wireless connectivity, then this is the subwoofer for you. The SuperCube 4000 (along with the SuperCube 6000) is the newest model in the famed SuperCube Series and incorporates the latest digital technologies for bass performance that will leave you slack-jawed in amazement and delight. Definitive’s engineers redesigned every part for maximum performance and added convenience and connectivity features that make them easy to use, versatile and perfectly tailored to your system and room for heart-pounding bass that will not fail to astound your friends and neighbors. 

The SuperCube 4000 delivers explosive bass response for movies. But there’s more to home entertainment than rocket blasts and explosions—there is also 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 today by music fanatics and the very first thing they 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’s not a Definitive.

  • newegg Features in the Service of Superior Performance The most obvious departures from previous SuperCube models are the addition of a digital display (cleverly hidden under the grille cloth) and a wireless remote. They’re much more than a light show for the easily amused; they’re serious performance optimizing tools for perfectly blending the subwoofer to your system and room and correcting for differences in program material. For everyday use the remote makes it easy to set just the right amount of bass output to compensate for program material differences. As you make settings adjustments, the hidden display lights up to indicate the setting value and then turns off a few seconds later. You’ll get exactly the bass performance you want – effortlessly at the touch of a button.
  • newegg Digital Tracking Amplifier for Clean High Output The SC4000 features a designed-from-the-ground-up brawny 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. As well as being powerful, the new Definitive amps are environment-friendly. The amplifiers go into idle mode after less than 30 minutes after the cessation of signal. When in idle mode the amp draws a mere half Watt or less of current, meeting international standards for low energy consumption.
  • newegg Computers in the Subwoofer Exert Precise Control The SuperCube 4000 has an integrated 56 bit Digital Signal Processor (DSP)–in essence a mini computer–that extends and improves the bass response. Multi-band digital protection systems tightly monitor and control the woofer system to prevent distortion and woofer damage at ultra-high volume levels with a minimum of audible artifacts. In contrast to simpler one-band compression/limiting circuits used in competing subwoofer amp designs, the Definitive subs feature a Multiband Dynamic Range Optimizer (M-DRO) that divides the frequency range into multiple bands. If the DSP detects an overdrive condition in the upper bass range, it applies just the right amount of compression and to prevent distortion to just that range without compressing the low bass, thereby vastly reducing the audible compression artifacts. The bottom line is that SuperCube bass is always tight, highly detailed and distortion free.
  • newegg 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.
  • newegg High-Definition Subwoofer Drivers Deliver Superior Detail and Lightning-Fast Transient Response The SuperCube 4000 features a new 8-inch (20cm) subwoofer driver pressure coupled to two 8-inch (20cm) Ultra Low Bass Radiators delivering rock-solid low distortion bass, reaching down to the lowest frequencies, with an outstanding quality of superior transient response (“tightness”). 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. 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.
  • newegg A Full Range of Inputs Facilitates Easy Hookup to Any System The SuperCube 4000 can connect to any audio system via your choice of single cable LFE, stereo line level and speaker wire level inputs. Or you can choose to go wireless with the optional wireless connectivity kit for the ultimate in connection convenience.
