Space Saving Bass Boosting KEF KC62 Sub

KEF has developed three 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, says the company.  

KEF says its 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 expectations of subwoofer design forever, claims the maker. KEF says the cabinet is incredibly sufficient at withstanding a range of bass production, from deep thunder to quick and sharp agile bass without moving.

Size isn’t everything

With a new compact and sleek design, the KC62 subwoofer has been created to deliver impressive depth and accuracy in equal measure. This is a result of the patent-pending, ground-breaking Uni-Core technology, which is a new take on subwoofer engineering. KEF says it 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.

Uni-Core

To simultaneously deliver high-quality 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. In short, Uni-Core enables the subwoofer to deliver high performance and powerful, dynamic, accurate sound in an ultra-compact size. Along with the space-saving Uni-Core, other technologies also add to the performance of the unit.

‘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. This design 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 has been created to help 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 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, says KEF. 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 a favourite high-octane action sequence.

Well connected and versatile

The KC62 is also versatile, says it’s creator, 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. KEF says the KC62 can sonically integrate into any environment or listening room thanks to the five pre-set Room Placement Equalisation feature, which ensures the same performance from KC62 no matter where it is placed. 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

KEF also underlines the aesthetic qualities of the speaker.  The KC62 is crafted from extruded aluminium, creating a curved cabinet which 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.
