The KEF KC62 Uni-Core™ Force-Cancelling subwoofer is a new compact and sleek design featuring the recently announced, patent-pending, Uni-Core technology, which is an entirely new take on subwoofer engineering.

The Uni-Core design aims to deliver ultra-compact size along with performance and sits at the heart of the new KC62.

The KC62, along with the space-saving Uni-Core, features another two new technologies.

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 design that resists the internal air pressure without adding excessive mass, allowing the driver to move as required by the audio signal. KEF says that 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.

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.

Class D Amps

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.

The KC62 is also versatile, with a collection of connection options that allow it to work with almost any audio system. The line output with HPF allows for 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.

Simple Set-Up

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

Extruded Aluminium

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.
