Revolutionary sound absorption with MAT™

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.

The exquisite detail and clarity delivered across the R Series range results from a selection of tweaks and modifications specifically for this collection. From the refined tweeter gap damper that tames resonances for improved detail, to the flexible Decoupling Chassis which prevents unwanted vibrations for better clarity. The hybrid aluminium bass drivers produce tight, deep, and controlled bass, and the enhanced crossover design and fine-tuned signal path result in pristine, clean sound. These innovations combine to ensure the R Series sound even more transparent and life-like than previously heard on this already exceptional range.

A versatile collection

The R Series comprises seven models, providing listeners with great versatility when building their ideal HiFi system. Whether that’s a stereo or a home theatre set up, they can do so with the confidence that they will enjoy an immersive, realistic sound experience.

A trio of floor standing speakers, including R11 Meta, R7 Meta and R5 Meta and a bookshelf speaker R3 Meta, reproduce high-fidelity stereo sound for listeners favourite music irrespective of the dimensions of the listening space. Each of them will allow users to discover depth and detail they never knew existed – from a scrap of plectrum on a guitar string to the sense of emotion and atmosphere in a live performance.

The two centre speakers, including R6 Meta and R2 Meta, which can also be used in LCR (Left-Centre-Right) configuration, deliver brilliant dialogue clarity to the home theatre experience in different room sizes. Identically sized Uni-Q arrays are deployed on the centre speakers and all other models in the series. This creates a consistent sound character, ensuring that the focus is entirely on the film and not the equipment around the room.

If users want to experience immersive Dolby Atmos sound, the R8 Meta surround speaker is an ideal addition to the system. It can be either wall-mounted or placed on top of another R Series loudspeaker for unparalleled sound. With the addition of any of KEF’s class-leading subwoofers, the whole cinematic experience is felt, from the deepest impact to the softest whispers.

Deceptively simple and elegant loudspeakers

The understated design aesthetic of the R Series is complemented by carefully selected colour options. Conceived to be at home in either traditional or modern interiors, each model in the R Series comes in a choice of three finishes: Black Gloss, White Gloss, and Walnut.

Two models also have their own signature finish options: the Titanium Gloss Special Edition for R7 Meta, and the Indigo Gloss Special Edition for R3 Meta. The R3 Meta also features threaded inserts that allow the speaker to be mounted securely onto the top of the KEF S3 Floor Stands, which also boast integrated cable management and a mass-loadable column.
