KEF’s KC62 subwoofer is the first to employ the company’s Uni-Core tech and integrates seamlessly with the LS50 Wireless II

KEF has unveiled its KC62 subwoofer following last week’s introduction of its Uni-Core technology. Priced at £1,400 and available from February in a choice of carbon black and mineral white, the KEF KC62 is the first model to employ the new Uni-Core tech designed to achieve greater bass from a small space.


Built around KEF’s patent-pending force-cancelling Uni-Core technology, the all-new design measures 246 x 256 x 248mm. The compact cabinet is crafted from extruded aluminium that is said to be sufficiently inert to handle a full range of bass duties without flexing.

Power and drive

The twin 6.5in (165mm) drivers are powered by 1,000W RMS (2 x 500W) of Class D amplification to achieve impressive levels of control and sudden bursts of power exactly when required, the company tells us. The driver cone surrounds feature a brand-new patent-pending development called P-Flex Surround. The pleated design is said to resist the acoustic pressure inside the cabinet without limiting sensitivity to deliver accurate and detailed bass reproduction.


As well as manual adjustments for level, crossover and phase, KEF’s Room Placement Equalisation feature enables the KC62 to integrate into any room acoustic and main speakers. It features KEF’s SmartConnect and is compatible with its KW1 wireless subwoofer adapter kit available as a £180 extra.

Headquartered, in those early years, in a Nissen Hut on the premises of Kent Engineering & Foundry in the UK, after more than half a century at the cutting edge of audio the company remains committed to excellence in sound. From ground-breaking Uni-Q technology to the bar-setting LS50 Wireless, KEF’s flair for the unusual – and sometimes controversial – balances an obsession with design in harmony with the most innovative engineering. KEF’s reputation for quality is founded on a refusal to compromise on aural authenticity or experience.
