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 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 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's not a Definitive.
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 an aid for chronic couch potatoes; they're serious performance optimizing tools for perfectly blending the subwoofer to your system and room and correcting for differences in program material.
In an ideal audio system the subwoofer works "invisibly," simply adding deep, loud bass without calling attention to itself—blending seamlessly with the main speakers. The key to seamless main speaker/sub blending is finding the perfect crossover frequency, equalization and phase settings for your system and room. And the best place to make those "set and forget" adjustments is from your listening chair via a wireless remote. 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 light 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.
Digital Tracking Amplifier for Clean High Output
The SC8000 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.
As well as being powerful, the new Definitive amps are environment-friendly. The amplifier goes into idle mode less than 30 minutes after the cessation of signal and draws a mere half Watt or less of current, meeting international standards for low energy consumption.
Computers in the Subwoofer Exert Precise Control
The SuperCube 8000 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.
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 8000 is finished in gorgeous piano-gloss black.
High-Definition Subwoofer Drivers Deliver Superior Detail and Lightning-Fast Transient 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.
The SuperCube 8000 features a new 11-inch (28cm) subwoofer driver pressure coupled to two 12-inch (30cm) Ultra Low Bass Radiators. The total piston area is greater than a 18-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 a compact enclosure. The SuperCube 8000 can fill the largest domestic spaces with loud, visceral, extended and musical bass yet it occupies only 1.8 square feet of floor space!
