KEF’s new Uni-Core technology enables a smaller speaker or subwoofer cabinet while still delivering superb sound performance. Via two force-canceling drivers with overlapping voice coils driven by a single motor, KEF is able to reduce cabinet-size due to the voice-coils that are different sizes and yet take up the same amount of space within the driver configuration. The KEF Uni-Core technology will be included in a soon-to-be-released KEF product this month.

Here’s more about KEF’s new innovation:

Audio Manufacturer KEF is releasing a brand new groundbreaking technology called Uni-Core, which delivers a completely new take on speaker and subwoofer design. This latest innovative technology developed by KEF redefines size versus performance by enabling high-level performance while reducing the subwoofer or speaker cabinet volume significantly.

With the ambition to create an aesthetically pleasing piece of audio equipment to complement your living room, it was also imperative that KEF not only maintain but excel in their delivery of accurate and deep bass. Between desirable aesthetics and uncompromising performance the first challenge was fitting two drivers into a compact cube enclosure.

"To deliver deep and loud bass from a compact product is a big engineering challenge,” says Dr. Jack Oclee-Brown, Head of Research & Development at KEF. “The Uni-core is a breakthrough technology for KEF because it allows us to pack two drivers into a tighter space without compromising their performance."

Uni-Core uses two dual force-cancelling drivers with concentrically arranged, overlapping voice coils, that are driven by a single motor to provide stunning bass performance from a small enclosure. The voice-coils are different sizes and occupy the same physical space within the Uni-Core driver assembly. This allows for an extremely compact physical cabinet with significantly reduced volume when compared to subwoofers that rely on conventional driver technology.

The saved space provides the drivers far more excursion than an equivalent-sized, force-cancelling design, unlocking more output and depth from much less space. This patent-pending technology smoothly delivers powerful and deep bass response while removing the space concerns that are often obstacles to premium subwoofer performance.

The new Uni-Core technology will be applied in an upcoming KEF product that will be announced this month. To discover more on KEF, please visit:
