Metamaterial Absorption Technology

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.

Coming to a speaker Near you A new technology as exciting as Metamaterial Absorption Technology requires a great platform from which to perform. Rest assured, new KEF speakers that benefit from Metamaterial Absorption Technology will be here soon. The performance benefits will blow you away.
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.
