The Biggest Small Subwoofer

KC62 is an incredibly compact subwoofer that delivers the might and magic of deep, accurate bass for a thrillingly immersive music, movie and gaming experience. Created using innovative KEF engineering including the ground-breaking Uni-Core® technology, the football-sized KC62 features two 6.5inch force cancelling drive units powered by 1,000W RMS of specially designed Class D amplification.

Don’t let the size fool you

Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. KC62 is David to their Goliath; an ultra-compact subwoofer capable of delivering accurate, deep bass for an immersive music, movie and gaming experience at complete odds with its modest dimensions. And just as David beat Goliath, so KC62’s performance renders these subwoofer behemoths obsolete.
Uni-Core® Technology
Craving an immersive entertainment experience but put off by bulky subwoofers? KC62’s patented Uni-Core® technology revolutionises the traditional force cancelling design to deliver deep accurate bass from an ultra-compact cabinet. Combining both drivers into a single magnet system allows cabinet size to be reduced by over a third, while also increasing excursion to unlock exceptional output and depth.

1,000W RMS

Turn up the Power

KC62’s twin drivers are powered by 1,000W RMS (2 x 500W) of specially designed Class D amplification, providing exceptional levels of control and the ability to deliver sudden bursts of power when required, for example when enjoying your favourite high-octane action sequence.

5 Pre-sets

Same performance, everywhere

KC62 slips effortlessly into any environment or listening room, with the five pre-set Room Placement Equalisation feature ensuring the same performance no matter where you decide to place it; in free space, next to the wall, in a corner, nestled within a cabinet or using the dedicated apartment mode.

Well Connected

KC62’s connection options allow it to be used with almost any audio system, with KEF SmartConnect and speaker level inputs eliminating any connection issues. Line output with High Pass Filter (HPF) allows for exceptional fine-tuned integration, and KC62 is also compatible with the KW1 for simple wireless compatibility.

Design meets substance

Crafted from extruded aluminium, KC62’s curved cabinet perfectly blends form and function, providing strength and beauty. Small enough to blend into any décor, the Carbon Black, Mineral White and Titanium Grey finishes also make KC62 an exceptionally attractive statement.

Accurate, deep bass with speed and power

Accuracy is a KEF hallmark, whether in full-range loudspeakers or in subwoofers dedicated to delivering sensational bass. An array of innovative technologies come together to ensure KC62’s bass accuracy, including the P-Flex surround for precise driver movement and Smart Distortion Control Technology that reduces distortion, while performance is maximised via KEF’s Music Integrity Engine.

P-Flex (aka Origami Surround)

The P-Flex driver surround has a unique pleated design inspired by Origami, the Japanese art of paper folding, engineered to better resist the acoustic pressure in the cabinet to allow the driver to move more precisely compared to traditional surround designs. The result is deeper bass extension and a more accurate and detailed bass reproduction.
