KEF‘s new take on subwoofer and speaker designs with the Uni-Core technology. The patent-pending Uni-Core technology delivers compact size and performance, ‘creating the audio lover’s dream of a powerful but discreet subwoofer or speaker’. The new Uni-Core technology, developed by KEF, has been said to redefine the size versus performance battle. The technology enables maintained performance whilst reducing the subwoofer or speaker cabinet volume. The evolution of KEF’s technology has been met with KEF’s desire to create a timeless design with acoustic inventiveness.

Acknowledging the ambition to create an aesthetically pleasing piece of audio equipment to complement a living room, it was also imperative that KEF not only maintained but excelled in its provision of accurate and deep bass. With this aim of desirable aesthetics and uncompromising performance the first challenge was how to fit two drivers into a compact cube enclosure.

“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.” says Dr Jack Oclee-Brown, Head of Research & Development at KEF.

With the new Uni-Core topology, dual force-cancelling drivers provide bass performance from less space by means of concentrically arranged, overlapping voice coils. Furthermore, Uni-Core allows a single motor to energise both cones. The coils are different sizes on each cone, which means when the cones move backwards the coils can occupy the same space within the cabinet. Overall it means that the physical cabinet can be extremely compact and significantly reduced in volume 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. This patent-pending technology ‘smoothly delivers the aspirational design and audio excellence’ explains KEF.
