Introducing the KEF R Series with Metamaterial Absorption Technology

Experience sound like never before with the KEF R Series, featuring the revolutionary Metamaterial Absorption Technology (MATTM). Built on decades of acoustic innovation, the R Series delivers unparalleled detail and insight, igniting excitement every time you listen.

The R Series incorporates cutting-edge technologies developed for the class-leading Reference series, ensuring exceptional performance. The latest iteration of the R Series features MATTM, a highly complex structure that absorbs unwanted sound, resulting in a purer and more natural acoustic performance. With the 12th generation Uni-Q driver array, refined to maximize the impact of MATTM, the R Series delivers an exceptional audio experience.

With seven models to choose from, the R Series caters to all audio preferences, whether you’re a two-channel HiFi enthusiast or a multi-channel home theater lover. Prepare to be amazed by the levels of detail and clarity that the R Series brings to your audio setup.

Unleash the Power of Metamaterial Absorption Technology

At the heart of the R Series lies Metamaterial Absorption Technology (MAT), a revolutionary innovation that takes the Uni-Q driver array to new heights of accuracy and clarity. The intricate channels within the MAT structure efficiently absorb specific frequencies, acting as an acoustic black hole that eliminates 99% of unwanted sound from the rear of the tweeter. This breakthrough technology ensures a purer and more natural sound reproduction, free from distortion.

Unrivaled KEF Sound Quality

The bespoke 12th generation Uni-Q driver array with MAT is present in all seven models of the R Series, delivering an incredibly detailed performance. Years of in-house knowledge and cutting-edge simulation and analysis tools have gone into its design. The redesigned Uni-Q driver array maximizes the performance improvements brought by MAT, while the specially designed conical waveguide and strategically placed tweeter gap damper further enhance detail and clarity.

The ultra-low distortion midrange motor design, featuring a copper ring embedded into the motor gap, ensures improved efficiency and reduced thermal compression. The Flexible Decoupling Chassis, used in the Blade and Reference series, is employed to minimize coloration caused by midrange vibration transmission. Additionally, the surround on the Uni-Q driver array allows for longer excursion without diffraction, extending the midrange’s frequency range.

Experience Transparency and Life-like Sound

These innovations combine to make the R Series sound even more transparent and life-like than ever before. The result is a pristine, clean sound that immerses you in your favorite music and movies.
