About the R Series?

An Icon born from The Reference

Since 1961, KEF??s quest to reproduce immaculate sound has led to many acoustic innovations. The Reference is a case in point. Distilling decades of experience into an acoustic performance that is nothing short of exceptional, it is a design that continually sets the benchmark for loudspeakers and sound reproduction. Now the latest technological innovations have also made their way into the R Series.

Metamaterial Absorption

Absorbs 99% of unwanted sound for pure and natural sound.?

At the heart of the R Series is Metamaterial Absorption Technology (MAT?). MAT? is a highly complex maze-like structure that absorbs 99% of the unwanted noise from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.

Uni-Q? - Sit anywhere, hear every detail

A 12th?generation Uni-Q??driver array with MAT? is found in all seven models of the R Series. Uni-Q? acts as a single point source to disperse sound more evenly through the room. The result is the elimination of the limited ??sweet spot??, therefore allowing everybody, wherever in the room they may be, to experience and enjoy the same natural, detailed sound.

Performance defined

The R Series is engineered to be acoustically exceptional. Every element of the design has been precisely tuned to deliver more detail and deeper insight, recreating the exhilaration of hearing an original music performance, with all the emotion and nuance that goes with it.

A Flare for Detail

Derived from The Reference, 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.

Critical damping

A solid platform is imperative for great sound. The R Series benefits from constrained layer damping, a system that uses internal braces joined by a ??lossy?? interface. This material converts unwanted vibration into heat, ensuring that the cabinet makes the only sound it needs to: the sound of silence

True bass definition

R Series bass drivers have a two-part structure with a shallow, concave, aluminium skin atop a paper cone. This stiffness, combined with the cone??s unique geometry, achieves a piston-like movement for punch and speed. The drivers?? magnet system creates a broad and uniform magnetic field which means more impressive and impactful bass.

Flexible port for cleaner bass

We only want to hear the drivers, not the resonances or turbulence created by a bass port. 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.

Strength and versatility in numbers

With a choice of matching home theatre models to pair with, the stage is set for an immersive movie experience.

R Series offers a choice of floorstanding speakers, bookshelf speakers, centre channel speakers and accompanying home theatre models. Each one offers the finest sound KEF has ever delivered in its category, whatever the dimensions of the room or system configuration.
