R Series loudspeakers revamped by KEF

KEF has announced the launch of its new R Series. No fewer than 1,043 individual changes have been made for the new R Series

The latest,12th generation of KEF’s Uni-Q driver is at the heart of the new range. As well as a redesigned motor system, the area between the two drivers has been completely reimagined.

The design of Uni-Q necessitates a narrow gap between the drivers, which can be excited by sound waves at certain frequencies. The new structure and damping system “…eliminates these resonances, resulting in an even more smooth, transparent and detailed treble performance than ever before,” said the company.

The Uni-Q Driver array’s role as a waveguide is further expanded by KEF’s ‘Shadow Flare’ trim ring design.

For the new R Series, KEF has completely re-worked the low-frequency drivers. The new bass drivers have greater excursion, as well as an improved motor and a new cone.

The new R Series also utilises a new internal bracing system called Constrained Layer Damping. Originally developed for the LS50, the system uses internal braces which connect to the cabinet panels via a lossy interface (as opposed to being fixed rigidly). 

All the ports in the R Series speakers are “precisely positioned” and flexible walls, which prevent, “…longitudinal resonances from colouring the midrange,” said the company.

A suede-like, microfibre grille design, utilises 1801 precision-cut holes for each driver.

The new R Series consists of the R11, R7 and R5 floorstanders, the R3 standmount, the R2c centre speaker and the R8a Dolby Atmos-compatible speakers. 

All the loudspeakers in the range come in three contemporary finishes: Black Gloss, White Gloss and Walnut.

    These look awesome. I wonder if there will be a wireless version of the R5. I would love an active floorstander

    Well, we’ve had a new active speaker from KEF (the LSX), but still no active floorstander : – (
    Where is the R5 wireless?
