KEF launches the R Series with Metamaterial Absorption Technology (MAT)

For over six decades, KEF has been the leader of audio excellence, committed to pursuing sound perfection and developing high-fidelity sound systems. Once again, KEF is redefining soundscapes with the latest generation of the R Series HiFi Speakers, now featuring the ground-breaking Metamaterial Absorption Technology (MATTM). The R Series is an exceptional seven-model range engineered to provide superior performance with more detail, deeper insight and greater excitement.

Bringing brilliant sound to shows, games and artists like never before, the new R Series includes a selection of the latest technologies developed for KEF’s class-leading and category-defying, The Reference. Making exceptional sound experiences more accessible, the R Series can be enjoyed in stereo for music or in a home theatre set up. With a contemporary, timeless design driven by acoustics, this collection of HiFi Speakers gives users even more ways to easily connect with the content they love.

At the heart of the latest R Series is Metamaterial Absorption Technology (MAT), a highly complex maze-like structure where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural acoustic performance.

A bespoke 12th generation Uni-Q driver array with MAT is found in all seven models of the R Series and delivers an incredibly detailed performance. It’s the result of decades of accumulated in-house knowledge and the application of cutting-edge simulation and analysis tools. The developments are many, and all play a part in R Series’ exceptional performance.
