KEF R3 3way Bookshelf Speakers - White Gloss

The R3 redefines standmount performance. No surprise, as it shares the same drivers as the range-topping R11. A true three-way speaker, the 165mm (6.5 in.) bass driver pushes bass performance to new extremes. The 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium dome tweeter creates a Uni-Q array that defies the expectations from the most compact main speaker in the range.

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 R3 redefines standmount performance. No surprise, as it shares the same drivers as the range-topping R11. A true three-way speaker, the 165mm (6.5 in.) bass driver pushes bass performance to new extremes. The 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium dome tweeter creates a Uni-Q array that defies the expectations from the most compact main speaker in the range.

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.

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 transition 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.

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.
