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.

Smart Distortion Control Technology

The KC62 also innovates with the patent-pending, sensorless Smart Distortion Control Technology.
This ground-breaking motional feedback system helps correct any minute abnormalities that may
occur. It does this by measuring the current in the voice coil and detecting and correcting any non-linear
distortions. This reduces the total harmonic distortion (THD) by up to 75% and thus delivers a more
accurate, less coloured bass performance.

Music Integrity Engine

KC62‘s performance is finetuned even further by 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.

Turn up the Power

The final piece of the performance puzzle is amplification, which the KC62 has in abundance. The 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.

line output with HPF allows for exceptional fine-tuned integration, while KEF SmartConnect eliminates
any connection issues. The KC62 is also compatible with the KW1 for wireless compatibility with the
minimum of fuss.

Same performance, everywhere

KC62 slips effortlessly into any environment or listening room, thanks to the five pre-set Room
Placement Equalisation feature, which ensures you get the same performance from KC62 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.

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.
