The KEF R3 Meta Bookshelf Speakers enhance your favourite music and provide seamless connectivity to your amplifier. 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) optimises 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 colour variations, including black and white gloss, walnut, and special edition indigo, as eye-catching as its sound is gripping. The Wireworld Helicon 16 speaker cable will enable clear signal transfer so you can get engrossed in your music.
For over sixty years, KEF has built pioneering HiFi speakers capable of producing reliable and accurate sound. Through thorough testing and acoustic expertise, KEF have now fully invigorated the R Series with advanced components originally developed for their benchmark Reference Series speakers. The award-winning MAT™ (Metamaterial Absorption Technology), the latest tool available to the R Series, uses maze-like channels to eliminate 99% of unwanted sound from the rear of the driver, specially developed for a truer response.
Rejuvenated Uni-Q Array
Anyone familiar with KEF speakers will instantly recognise the signature Uni-Q driver array. The principle of this design places the tweeter in the centre of the mid/bass cone, creating a single acoustic source. This classic KEF innovation, along with the newly introduced MAT driver design, an ultra-low distortion midrange motor, Shadow Flare waveguide surround, and a host of other technologies inspired by the Reference Series ensures that the unique Uni-Q Array performs more accurately than ever before, with an ultra-wide listening arch that defies the “sweet spot”.
Hybrid Low-Frequency Driver
Underlining the three-way design of the KEF R3 Meta, a 6.5-inch hybrid aluminium cone driver sits below the Uni-Q Array. As the name would imply, this driver consists of a thin aluminium layer atop a paper cone. The combined strength of these two materials ensures the rigidity of the driver during use, resisting the strenuous kinetic energy of bass production. As a result, the R3 can deliver deep low-frequency sound whilst retaining precision and detail. The geometry of the driver also expertly manages resonance and improves time alignment with the Uni-Q Array.
