KEF KC92 Subwoofer Power The KEF KC92 subwoofer delivers a remarkably deep and impactful bass experience. It uses twin 9-inch force-cancelling drivers, propelled by a formidable 1000W RMS of custom Class D amplification. Therefore, this compact sealed cabinet achieves exceptional precision and clarity. The unit provides visceral, detailed low-frequency sound that drops you right into the heart of the action. Engineering KEF’s proprietary Music Integrity Engine, or MIE, guarantees acoustic accuracy. This sophisticated DSP ensures every component of the subwoofer works perfectly together. Furthermore, features like iBX Intelligent Bass Extension provide deeper, precise bass at all listening levels. Its P-Flex Surround is engineered to resist cabinet pressure effectively, allowing the driver to move with increased accuracy compared to traditional designs. Design The twin drivers are set in a force-cancelling configuration. This layout effectively neutralises reactive forces, which in turn facilitates sound pressure levels up to 110dB from a small, sealed enclosure. The hybrid aluminium and paper cones feature an oversized motor system and a vented voice coil design. Consequently, this engineering minimises distortion to vanishingly low levels, delivering exceptional precision and clean depth. Connectivity Setting up this subwoofer is effortless thanks to versatile connections, including KEF SmartConnect and speaker level inputs. Fine-tuned integration is available via a line output which incorporates a High Pass Filter. Moreover, five intuitive room position EQ options guarantee excellent performance regardless of where the unit is situated. For even greater output, a stacking kit allows merging up to three units, providing immense power without taking up excessive floor space.
