It delivers tight, precise, and musical bass notes with clear pitch, enhancing both music and movie soundtracks. Designed by audio enthusiasts, this subwoofer is rigorously tested with music to ensure exemplary performance. Advanced Features for Superior Performance New additions include a hidden digital display and wireless remote control, enabling effortless optimisation of crossover frequency, equalisation, phase settings, and volume from your listening position. The remote allows quick adjustments to suit different program material, ensuring seamless integration with your main speakers. Powerful Digital Tracking Amplifier The built-from-scratch 1200 Watt digital tracking amplifier delivers low distortion and high output, handling sustained bass and transient peaks like bass drum kicks and on-screen effects with ease. It also features an energy-saving idle mode, reducing power consumption to less than half a Watt after 30 minutes of inactivity. Precision DSP Control The integrated 56-bit DSP acts as a mini-computer, extending and refining bass response while protecting the woofer with a Multiband Dynamic Range Optimizer (M-DRO). This system compresses only the necessary frequency bands to prevent distortion, resulting in tight, detailed, and distortion-free bass. Rock-Solid Cabinet Construction The subwoofer cabinet is engineered to be inert and vibration-free, with nearly 2-inch thick front and rear panels and multiple internal braces. This ensures pure sonic reproduction with minimal distortion. The SuperCube 4000 is finished in a stunning piano-gloss black lacquer. High-Definition Drivers for Superior Detail The SuperCube 4000 features an 8-inch high-excursion active subwoofer driver coupled with two 8-inch Ultra Low Bass Radiators. This design provides greater piston area than a typical 12-inch woofer, delivering faster, more musical, and controlled bass from a compact enclosure. Connectivity Connect easily to any audio system via LFE input, stereo line level, or speaker wire level inputs.
