    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.

    Class HD 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.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 refurbished 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.

    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 refurbished SuperCube 4000 features a new 8–inch (20cm) subwoofer driver pressure coupled to two 8–inch (20cm) Ultra Low Bass Radiators. The refurbished 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!
