Revolutionary sound absorption
A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that eliminates unwanted sound from the rear of driver, resulting in a purer, more natural performance.
Created to eliminate 99%
Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new properties. MAT’s tuned channels absorb 99% of the unwanted sound from the rear of driver, compared to around 60% absorption from loudspeakers using different approaches.

Always innovating
KEF always pushes the technological boundaries in its mission to create the best possible sound; MAT is the physical manifestation of that drive. The result of a joint development project with the Acoustic Metamaterials Group, MAT breaks completely new ground in loudspeaker design.
Uni-Core™
KEF’s innovative, patent-pending Uni-Core™ technology redefines the physical space high-performance speakers and subwoofers required to deliver deep and accurate bass. Through exceptional engineering and creativity, KEF’s engineers have revolutionised the traditional force cancelling arrangement with a Uni-Core™ design that delivers deeper bass from ultra-compact cabinets.
Uni-Q
KEF’s many pioneering innovations are all geared towards delivering breath-takingly natural sound; sound that lets you enjoy music as it was meant to be heard. Of all these pioneering developments, it is the Uni-Q driver array that sits at the heart of almost all our speakers.
