KEF KC62 Uni-Core Force Cancelling Subwoofer Don’t let the size fool you 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 delivered in 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. Accurate, deep bass with speed and power P-Flex Surround (aka Origami Surround) The second of the three new technologies in KC62 is a brand-new design of driver surround. The new, patent-pending P-Flex surround is engineered to better resist the acoustic pressure in the cabinet without limiting sensitivity in the same way traditional surround designs do. To achieve this, it uses a unique pleated design inspired by Origami, the Japanese art of paper folding, which resists the internal air pressure without adding excessive mass, allowing the driver to move precisely as required by the audio signal. The result is deeper bass extension and a more accurate and detailed bass reproduction.
