Definitive Technology SuperCube 4000 Powered Subwoofer



Good condition with box. No remote.

Product Description

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.

The SuperCube 4000 features a new 8-inch (20cm) subwoofer driver pressure coupled to two 8-inch (20cm) Ultra Low Bass Radiators. 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. The SuperCube 4000 can fill most domestic spaces with loud, visceral, musical bass yet it occupies less than a square foot of floor space.

The SuperCube 4000 can connect to any audio system via your choice of single cable LFE, stereo line level, or speaker wire level inputs. Or you can choose to go wireless with the optional wireless connectivity kit for the ultimate in connection convenience.
