UK-based loudspeaker company, KEF has created a new technology to transform the design of subwoofers and speakers.
Tackling the battle of size versus performance, the new patent-pending Uni-Core technology delivers high-level performance while reducing the subwoofer or speaker cabinet volume significantly.
Striving to be aesthetically pleasing but not compromising on performance, KEF had to overcome the challenge of fitting two drivers into a compact cube enclosure.
“To deliver deep and loud bass from a compact product is a big engineering challenge,” explained Dr. Jack Oclee-Brown, head of research and 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.”
With the new Uni-Core topology, dual force-cancelling drivers provide bass performance from less space by means of concentrically arranged, overlapping voice coils. The technology also allows a single motor to energise both cones. The coils are different sizes on each cone, meaning that when the cones move backwards, the coils can occupy the same space within the cabinet.
Ultimately, this allows the physical cabinet to 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, delivering more output and depth from less space.
This new patent-pending technology will be applied in an upcoming new KEF product to be announced later this month.
