Metamaterial Absorption Technology
WHAT HI-FI? AWARDS 2020 - 'INNOVATION OF THE YEAR'
“KEF has taken an excellent speaker and made it even better with its innovative Metamaterial tech. The LS50 Metas are now the class leader at this level.” - September 2020, What Hi-Fi?
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.

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.DOWNLOAD MAT™ AES PAPER

Single Apparent Source
Single Apparent Source technology aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point. Perfectly calibrated drivers that cover the entire bandwidth of the loudspeaker are configured so that all frequencies appear to radiate from one single point. The result is noticeably more precise imaging and highly accurate sound across a wider area.EXPLORE MORE
