The KEF R3 Meta Bookshelf Speakers are ideal for high-performance home audio, inheriting technologies from over sixty years of loudspeaker innovation. Featuring components originally developed for the premium Reference Series speakers – a benchmark for quality – these bookshelf speakers can control a room without dominating its floor space. The celebrated Metamaterial Absorption Technology (referred to as MAT) optimize the classic KEF Uni-Q Array and diminishes unwanted sound by up to an incredible 99%. This, along with a host of ingenious advancements, keeps distortion to a minimum and widens the listening sweet spot. Get closer to the original sound with the KEF R Series. These speakers have been designed in four distinct color variations, including black and white gloss, walnut and special edition indigo, as eye-catching as its sound is gripping.
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.
Performance 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.
