KEF R7 Floorstanding Speakers (Pair), Walnut

The new KEF R Series has been completely re-engineered from the ground up. The only thing to remain the same is the name. Decades of experience and KEF's 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.

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. With a pair of 165mm (6.5 in.) hybrid aluminium bass drivers and a Uni-Q combining a 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium dome tweeter, R7 outperforms all expectations.

Feel The Music
When you want to forget the world and simply lose yourself in sound, R Series will take you there. KEF's quest to develop perfect loudspeakers has lasted more than 50 years. Like you, they don’t just want to hear music; they want to experience it and feel part of it.

Great For Movies
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.

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 exterior. The R Series comes in two sleek gloss finishes or a classic wood veneer. The details are even 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.

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.

Uni-Q Driver
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.
