KC62 – KEF's new black or white subwoofer [€1'500] combines two 6.5" force-canceling woofers on either side with 1kW of class D power inside an extruded 14kg aluminium chassis of ultra-compact 246 x 256 x 248mm proportions. There are 5 DSP presets called room, wall, corner, cabinet and apartment to input automatic boundary gain compensation. This DSP also includes a smart limiter to avoid overdrive. Next come max 105dB SPL and a shocking -3dB/11Hz claimed reach. The RCA-based 4th-order low-pass filter is variable from 40-140Hz, bypassable for LFE signal and matched by a high-pass filter on RCA outputs. Alternatively, the latter can be used to daisy-chain a second subwoofer. The KC62 is the company's first model to exploit their new patent-pending Uni-Core array below which nests the voice coil of one woofer inside the other to allow them placed in closer proximity. These drive units also use the company's unique P-Flex surround which exploits pleats to better resist the acoustic pressure in the cabinet. Finally there's patent-pending motion feedback without sensor for real-time distortion reduction; and a wireless adapter input for tablet control.
