Now with Metamaterial Absorption Technology

Since 1961, KEF has strived to reproduce pure sound precisely as it was meant to be heard. Decades of experience in acoustic innovation and the quest for music perfection come together in the R Series to deliver sound with more detail and deeper insight, sound that ignites excitement every time you experience it.

The R Series is a direct beneficiary of the technological innovations developed for The Reference, the class-leading series that continually set the benchmark for loudspeakers and sound reproduction. Combining with bespoke technologies, the R Series delivers an exceptional acoustic performance. The revolutionary Metamaterial Absorption Technology1 (MATTM) has been incorporated into the latest iteration of the R Series, and the 12th generation Uni-Q driver array has been refined to maximise the impact of this technological advance and ensure the best possible performance.

The result is an exceptional seven-model range of loudspeakers, engineered to deliver with exquisite detail and incredible insight. Whether your taste lies with traditional two-channel HiFi, multi-channel home theatre or both, the R Series reveals levels of detail that must be heard to be believed.

Revolutionary sound absorption with MATTM

At the heart of the latest R Series is Metamaterial Absorption Technology (MAT), a revolutionary innovation that takes the performance of the 12th generation Uni-Q driver array to another level in terms of accuracy and clarity.

MAT is 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 that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural acoustic performance.

Superior KEF sound

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.

The Uni-Q driver array has been redesigned to maximise the performance improvements that MAT delivers. The conical waveguide that couples the tweeter dome to the new metamaterial absorber has been specially designed for the bespoke driver based on its depth. The re-engineered tweeter gap damper strategically places two rings of porous material to tame the resonances and imperfections effectively, thus greatly improving detail and clarity.

The ultra-low distortion midrange motor design uses a copper ring embedded into the motor gap to minimise inductance and variation of inductance with coil position. This lowers the midrange THD and reduces thermal compression, leading to improved efficiency.
