KEF R11 Meta (Walnut) Loudspeakers (Pair)

Flagship three-way floorstanding speakers

The R11 Meta is the largest floorstanding model of the R Series. For a breathtaking listening experience, its combination of 12th generation Uni-Q® driver array with MAT™ and four 6.5” hybrid aluminium bass drivers allow it to pick out the subtle details of a recording, while also delivering raw power and agility.

Now with Metamaterial Absorption Technology

Since 1961, KEF has strived to reproduce pure sound precisely as it was meant to be heard. Decades of experience in acoustic innovation and the quest for music perfection come together in the R Series to deliver sound with more detail and deeper insight, sound that ignites excitement every time you experience it.

The R Series is a direct beneficiary of the technological innovations developed for The Reference, the class-leading series that continually set the benchmark for loudspeakers and sound reproduction. Combining with bespoke technologies, the R Series delivers an exceptional acoustic performance. The revolutionary Metamaterial Absorption Technology1 (MATTM) has been incorporated into the latest iteration of the R Series, and the 12th generation Uni-Q® driver array has been refined to maximise the impact of this technological advance and ensure the best possible performance.

The result is an exceptional seven-model range of loudspeakers, engineered to deliver with exquisite detail and incredible insight. Whether your taste lies with traditional two-channel HiFi, multi-channel home theatre or both, the R Series reveals levels of detail that must be heard to be believed.

Superior KEF sound

A bespoke 12th generation Uni-Q driver array with MAT is found in all seven models of the R Series and delivers an incredibly detailed performance. It’s the result of decades of accumulated in-house knowledge and the application of cutting-edge simulation and analysis tools. The developments are many and all play a part in R Series’ exceptional performance.

The Uni-Q driver array has been redesigned to maximise the performance improvements that MAT delivers. The conical waveguide that couples the tweeter dome to the new metamaterial absorber has been specially designed for the bespoke driver based on its depth. The re-engineered tweeter gap damper strategically places two rings of porous material to tame the resonances and imperfections effectively, thus greatly improving detail and clarity

The ultra-low distortion midrange motor design uses a copper ring embedded into the motor gap to minimise inductance and variation of inductance with coil position. This lowers the midrange THD and reduces thermal compression, leading to improved efficiency

The Flexible Decoupling Chassis first used on the latest Blade and The Reference loudspeakers is employed on the Uni-Q driver array to dramatically reduce coloration of the sound caused by midrange vibration transmission to the cabinet, while also solving the problem of additional sound created by the driver basket that occurs with traditional decoupling methods. It works by decoupling the massive midrange motor from the Uni-Q chassis, dissipating its vibration before it can travel to the cabinet and be radiated as unwanted sound.

The surround on the 12th generation Uni-Q driver array allows for longer excursion without causing diffraction and extending the frequency range of the midrange. The contours of tweeter dome, midrange cone and surround are all computer-optimised to ensure a perfectly smooth transition to the cabinet.

These innovations combine to ensure the R Series sound even more transparent and life-like than previously heard on this already exceptional range.

Perfecting every detail

At KEF innovative engineering goes hand-in-hand with great design, and the product design team strives to create deceptively simple, elegant loudspeakers. While every design choice KEF makes is driven by acoustic performance, visual appeal is vitally important and the R Series proves that a loudspeaker can perfectly integrate into the room, both sonically and aesthetically.

This understated design aesthetic is complemented by carefully selected colour options. Conceived to be at home in either traditional or modern interiors, each model in the R Series comes in a choice of two sleek gloss finishes: Black Gloss, White Gloss and a classic wood veneer finish: Walnut. Two models also have their own signature finish option in the form of the Titanium Gloss Special Edition for R7 Meta and the Indigo Gloss Special Edition for R3 Meta.

The R3 Meta also features threaded inserts that allow the speaker to be mounted securely onto the top of the S3 Floor Stands, which also boast integrated cable management and a mass-loadable column.
