KEF unveils performance enhancing Uni-Core technology

New product on its way

by Andy Bassett

KEF has announced its new Uni-Core technology for subwoofers and speakers which delivers enhanced performance from an ultra-compact size.

Always a company with a flair for the unusual, KEF is attempting to address the size versus performance debate with the company’s new Uni-Core technology which enables high-level performance whilst reducing the subwoofer or speaker cabinet volume significantly. 

Having introduced the LS50 Meta speaker last year - the first to use Metamaterial Absorption Material to effectively absorb 99% of the unwanted sound radiating from the rear of the driver - KEF has now turned its attention to further forward thinking acoustic inventiveness by redefining the physical space required for high-performance speakers and subwoofers.

As the company pursues a goal of speakers that complement living spaces, it has to ensure any changes to the aesthetics don’t compromise the provision of accurate and deep bass. The challenge, therefore, is how to fit two drivers into a compact cabinet enclosure. 

The new Uni-Core topology features dual, force-cancelling drivers which provide bass performance from less space by means of concentrically arranged, overlapping voice coils. Since the coils on each cone are different sizes it means that when the cones move backwards, the coils can occupy the same space within the cabinet. Moreover, a single motor system can energise both cones. The result is a significant reduction in the volume of the speaker or subwoofer cabinet compared to using conventional driver technology. 

The space saved allows the drivers to have far more excursion than an equivalent-sized force-cancelling design, unlocking more output and depth from much less space.

Dr Jack Oclee-Brown, Head of Research & Development at KEF, said, “To deliver deep and loud bass from a compact product is a big engineering challenge. 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."

KEF has confirmed that this new patent-pending Uni-Core technology will be applied in an upcoming new product to be announced this month.
