Maximising bass yet minimising space

KEF has once again developed three innovative technologies that successfully prioritise design and sound in equal measure. Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers.

Through exceptional engineering and creativity, KEF engineers have developed a brand new approach and new technologies to accurately reproduce the original recording, bringing all the splendour, impact and emotion from music and films. Thanks to these innovative KEF technologies, the KEF KC62 Uni-Core™ Force-Cancelling subwoofer has changed our expectations of subwoofer design forever. The cabinet is incredibly sufficient at withstanding a range of bass production, from deep thunder to quick and sharp agile bass without moving.

Don’t let the size fool you
With a new compact and sleek design, the KC62 subwoofer also delivers unprecedented depth and breath-taking accuracy in equal measure. This is a result of the patent-pending, ground-breaking Uni-Core technology, which is an entirely new take on subwoofer engineering. KEF continues to revolutionise traditional expectations of what a subwoofer can achieve in particular the KC62’s force cancelling abilities. The Uni-Core design delivers ultra-compact size and big performance, which sits at the heart of the innovative KC62.

To simultaneously deliver unprecedented performance and the benefits of force cancelation Uni-Core combines the two through a single motor system with the voice coils concentrically arranged. This allows the cabinet size to be reduced by over a third whilst equalling or exceeding the driver excursion of a much larger subwoofer; unlocking more output and depth from less space. Uni-Core enables the subwoofer to deliver high performance and powerful, dynamic, accurate sound in an ultra-compact size.

The KC62 has proven its versatility with accurate, deep bass, speed and power. Along with the space-saving Uni-Core, a second and third technology allow the subwoofer to excel in the aforementioned ways.

P-Flex Surround, also known as Origami Surround

The P-Flex Surround is a brand-new patent-pending driver surround. It resists the acoustic pressure inside the cabinet without limiting sensitivity in the same way traditional surround designs do. To achieve this, it is uniquely pleated in such a way that is inspired by the Japanese art of paper-folding earning itself the nickname Origami Surround. It is this meticulous design that resists the internal air pressure without adding excessive mass, allowing the driver to move as required by the audio signal. The result is a deeper bass extension and a more accurate, detailed bass reproduction and distortion reduction.

Smart Distortion Control Technology

This patent-pending, sensorless, motional feedback system helps correct even the slightest abnormalities that may occur. It does this by measuring the current in the voice coil and detecting and correcting any non-linear distortions, which delivers more accurate, less coloured bass performance. The new approach reduces the interaction between signal, amplifier and driver, which dramatically decreases the potential for distortion.

Power that cannot be ignored

The KC62‘s performance is finetuned further still 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 continually analyses the signal to prevent clipping, work together to ensure the perfect relationship between all components.

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. Turn up the power; listen and believe.

A well connected and versatile subwoofer

The KC62 is also incredibly versatile, with a collection of connection options that allow it to work with almost any audio system. The line output with HPF allows for exceptional finetuned integration, while KEF SmartConnect eliminates any connection issues. The KC62 is also compatible with the KW1 adaptor kit for wireless compatibility with the minimum of fuss.

Same performance, everywhere

Intricate design does not require a complicated setup. The KC62 can sonically integrate 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. Achieve seamless integration in free space, next to the wall, in a corner, nestled within a cabinet or using the dedicated apartment mode.

Design meets substance

The design allows the KC62 to work sonically within your home. It is also an aesthetically pleasing addition to your space. The KC62 is crafted from extruded aluminium, creating a curved cabinet which perfectly blends form and function, strength and beauty. Whilst diminutive enough to blend into the décor, the Carbon Black and Mineral White finishes also make KC62 a beautiful statement.
