Don’t let the size fool you
Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. KC62 is 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. 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..
Design Meets Substance
The KC62 is not just designed to work sonically within your home, but aesthetically as well. Crafted from extruded aluminium, the curved cabinet perfectly blends form and function, providing strength and beauty. Whilst diminutive enough to blend into the décor, the Carbon Black and Mineral White 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.

Uni-Core Technology
Redefines size versus performance
KEF’s innovative, patent-pending Uni-Core technology redefines the physical space high-performance speakers and subwoofers required to deliver deep and accurate bass. Through exceptional engineering and creativity, KEF’s engineers have revolutionised the traditional force cancelling arrangement with a Uni-Core design that delivers deeper bass from ultra-compact cabinets.
Maximises bass, Minimises space
The innovative Uni-Core system overcomes the performance compromises when placing force cancelling drivers into a smaller cabinet. Uni-Core combines both back-to-back drivers into a single motor system. The overlapping, concentrically arranged voice coils allows for far more driver excursion than in other force cancelling design, unlocking more output and depth from less space.

5 DSP Settings
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.

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.

P-Flex (aka Origami Surround)
More accurate, more detailed
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.

Music Integrity Engine
Finetuned performance
A bespoke selection of in-house designed DSP (Digital Signal Processing) algorithms in the form of KEF’s Music Integrity Engine. Algorithms including iBX (Intelligent Bass Extension) and SmartLimiter, which constantly analyses the signal to prevent clipping, work together to ensure the perfect relationship between every component.
