R Series 2018

KEF New R Series - The only thing that's the same is the name.

KEF R Series Speaker Line in Black

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. It combines innovations drawn from the Reference Series with new bespoke technologies to ensure the new R Series delivers more detail, deeper insight, and greater excitement.

THE R SERIES

R Series offers a choice of three floorstanding speakers, a stand mount for more compact spaces and accompanying matching theater 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

The benchmark by which all KEF loudspeakers are judged, the Reference Series, is the home of cutting-edge technological innovation. Innovations that are the result of diligent, creative research and development by the very best engineers in the business. But innovation doesn't stop at Reference, and the new R Series is the beneficiary of many of the technologies, materials, and developments made in the creation of 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.

SCIENCE OF SOUND

Uni-Q

Placing the tweeter in the acoustic centre of the midrange cone brings the acoustic ideal of a single point source closer to realisation. The new R Series benefits from a new 12th generation of the legendary Uni-Q which has been extensively designed using KEF's in-house simulation and analysis tools. KEF's engineers have been able to dramatically reduce colouration through reducing resonance in the minute gaps between Uni-Q's separate elements. The resulting sound is purer, more precise, and makes stereo imaging far more believable.

KEF R Shadow Flare Technology

SHADOW FLARE

Derived directly from the Reference Series, the Shadow Flare is an innovative method of reducing harmful cabinet diffraction for delicate high frequencies. Shadow Flare is a carefully profiled transitional surface which extends the waveguide effect of Uni-Q. The tweeter no longer has line of sight of the cabinet edges, creating a 'shadow region' at the points where the potential for diffraction is highest. The result is vastly improved fine detail, particularly when it comes to the subtle nuances of plucked strings and other percussive sounds.

LOW FREQUENCY DRIVERS

Bass is the very foundation of music; everything is built upon it and maximising bass performance is a vital building block towards pristine sound. R Series bass drivers are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This great stiffness, combined with the cone's unique geometry, delivers pure piston like movement to deliver punch and speed. To accurately control this mighty driver, KEF has also completely redesigned its magnet system to create a more even magnetic field. The overall result is more impressive and impactful.

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.

FLEXIBLE PORT TECHNOLOGY

When it comes to generating deep, articulate bass, port design is crucial. The ports in R Series feature innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence, while the flexible port walls prevent longitudinal resonances from colouring the midrange.

BEAUTIFUL BY DESIGN

Great design is timeless. KEF's product designers seek to create deceptively simple, elegant loudspeakers. But form follows function. So whilst R Series is driven by acoustics, all visible engineering fixings have been artfully concealed so all the listener sees is a beautiful and simple exterior.

FINISHED TO PERFECTION

Conceived to be at home anywhere, the R Series comes in a choice of two sleek gloss finishes or a classic wood veneer. These finishes go deeper than just a base colour: each speaker benefits from KEF's tone-on-tone approach where tweeter dome, driver cones, feet, spikes, and KEF logo are colour-matched to the finish.

KEF R Series Matching Micro Fibre Grilles

MICROFIBRE GRILLES

The R Series has been created to sound at its best with or without grilles. This microfibre design is a first for KEF and resulted in a design that not only looks beautiful but has negligible effect on sound performance.

All of the grilles are hand crafted and compressed with heated pressure from thirteen layers of composite material. The grilles continue the tone-on-tone approach: grey for the white cabinet, brown for the walnut, and black for the black. The grilles edges are burnished in a similar way to fine leather goods and the overall effect is almost suede-like.
