THE ONLY THING TO REMAIN THE SAME IS THE NAME
The new KEF R Series has been completely re-engineered from the ground up. Decades of experience and our unbridled passion for music come together in the new R Series. Combining innovations from the Reference Series with bespoke technologies the new R Series delivers more detail, deeper insight and greater excitement.
R11
Flagship three-way floorstander
The largest model in the R Series combines four bass drivers and the latest generation Uni-Q for a powerful and refined sound.
R7
Mid-sized three-way floorstander
The R7 is the mid-sized floorstander in KEF's new R Series, very powerful yet not too large it brings music and movies to life.
R5
Compact three-way floorstander
KEF engineers do not believe in compromise, the R5 floorstander is compact and elegant yet it delivers music and movies with ease.
R3
Three-way stand mount
The R3 stand mount shares the same drivers as the range topping R11 in a full range design that defies expectations.
R2c
Three-way centre channel
Built to match any of the R Series floorstanders the R2c delivers the dialogue that brings movies to life in your home.
R8a
Dolby Atmos flexible surround
The R8a works as a surround or rear speaker and can bounce sound off the ceiling to create truly cinematic scale with Dolby Atmos.
KF92 Subwoofer
Twin 9-inch driver 'force-cancelling' subwoofer
KF92 is a compact, room-friendly subwoofer engineered to deepen every listening experience.
THE R SERIES
R Series offers a choice of three floorstanding speakers, a stand mount for more compact spaces and accompanying matching theatre models. Each one offers the finest sound KEF has ever delivered in its category whatever the dimensions of the room or system configuration.
R STARTS WITH REFERENCE
At KEF the Reference Series is the home of cutting-edge technological innovation. This is the result of diligent, creative research and development by the very best engineers in the business. The new R Series benefits from many of the technologies, materials and developments created for the Reference Series.
FEEL THE MUSIC
When you want to forget the world and simply lose yourself in sound, R Series will take you there. At KEF, the quest to develop perfect loudspeakers has lasted more than 50 years. Like you, we don’t just want to hear music; we want to experience it, get inside it and feel part of it.
SOUND IS THE REAL STORY
In the movie world, the best sound engineers are capable of weaving ever more wonderful sonic webs and the new R Series is your ticket for getting the best out of movies, delivering the natural, consistent sound essential for a phenomenal surround sound experience.
KEF makes a range of matching subwoofers to augment R Series with powerful and controlled bass.

Beautiful by Design
Form follows function in KEF loudspeakers, so while the R Series is driven by acoustics all fixings are hidden, so all you see is a beautiful, clean exterior. The R Series comes in two sleek gloss finishes or a classic wood veneer and KEF’s tone-on-tone style means that the details are colour-matched to the finish.
Microfibre Grilles
The R Series was created to sound its best with or without grilles. The microfibre grille design is a first for KEF and not only looks beautiful but has a negligible effect on performance. They continue the tone-on-tone approach to match the various cabinet finishes and the edges are burnished for a suede-like effect.
TECHNOLOGY
THE SCIENCE OF SOUND
THE SCIENCE OF SOUND
Uni-Q
The evolution of KEF's Uni-Q driver reaches its 12th generation in the R Series. Using simulation and analysis tools KEF’s engineers have been able to dramatically reduce colouration by cutting resonance in the tiny gaps between Uni-Q’s elements. The result is purer and more precise sound with stronger imaging.
Shadow Flare
The Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. It's a carefully profiled transition that extends the waveguide effect of Uni-Q. The treble escapes naturally because the ‘shadow region’ stops it getting to the cabinet edges. The result is vastly improved fine detail.
Cabinet Bracing
A solid platform is imperative for great sound. The new R Series benefits from Constrained layer damping. This system utilises internal braces joined by a ‘lossy’ interface and is highly effective at dissipating unwanted vibrations that would otherwise artificially change the sound and music.
Low Frequency Drivers
R Series bass drivers have a two-part structure with a shallow concave aluminium skin atop a paper cone. Combine this stiffness with the cone’s unique geometry and you get near pistonic movement for punch and speed. KEF has also increased linearity in the magnet system which means more impressive and impactful bass.
Flexible Port Technology
When it comes to generating deep, articulate bass, port design is crucial. The R Series ports have innovative flexible walls. Using computational fluid dynamics the flare and profile of each port is calculated to delay the onset of turbulence and the flexible port walls prevent resonances from colouring the midrange.
