Product Description

Definitive Technology SuperCube 4000 Subwoofer

The Definitive Technology SuperCube 4000 Subwoofer delivers 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.

Music Lovers Rejoice

Subwoofer manufacturers are always talking about how “explosive” their subwoofers are (frankly we do too), 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 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.

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 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.

Digital Tracking Amplifier for Clean High Output

The Definitive Technology SuperCube 4000 Subwoofer 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.

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.
