KEF KC62 Uni-Core Force Cancelling Subwoofer: The Biggest Small Subwoofer

Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. Thanks to three innovative KEF technologies, the KEF KC62 Uni-Core® force cancelling subwoofer has changed the rules of subwoofer design forever. Performance levels are at complete odds with this compact subwoofer’s football-sized dimensions, with unprecedented depth and breath-taking accuracy deliveredin equal measures.

Uni-Core® Technology

At the heart of KC62 is KEF’s innovative, patent-pending Uni-Core driver technology. A completely new take on traditional force cancelling arrangements, the Uni-Core design delivers ultra-compact size and big performance.

In order to simultaneously deliver unprecedented performance and the benefits of force cancelling from a compact size, Uni-Core combines both drivers into a single magnet system, with the voice coils concentrically arranged. This allows the cabinet size to be reduced by over a third, while equaling or exceeding the driver excursion of a much larger subwoofer, unlocking more output and depth from less space.

• Music Integrity Engine with iBX, SmartLimiter and Room Placement settings

    KW1 Wireless Subwoofer Adapter Kit: 

    Comprising a discreet transmitter and receiver, KEF KW1 works with the Kube, KC62 and KC92 subwoofers. It allows KEF subs to be optimally placed, and not limited by cables. High-quality wireless transmission delivers every ounce of detail and impact from your favourite films and music.

    The receiver is also available separately, allowing two KEF subwoofers to receive the same signal wirelessly from the same transmitter. 

    KW1 operates in the high-bandwidth 5GHz band and delivers audio up to 24bit/48kHz. The transmitter is powered by USB, while the receiver is powered directly by the subs expansion port. Pairing is intuitive and highly stable, while a range of up to 30m (line of sight) makes placement easy. KW1 is also perfectly suited for use with KEF's LSX II LT, LSX II, LS50 Wireless II and LS60 Wireless.
