The mid-sized KEF R7 Meta floorstanding member of the R Series is as powerful as it is flexible. Its 12th generation Uni-Q® driver array with MAT™ ensures a crystal-clear performance with music and movies alike, while its two 6.5” hybrid aluminium bass drivers deliver accurate, dynamic bass. Features Metamaterial Absorption Technology (MATTM) eliminates 99% of high-frequency distortion for pure, natural sound Bespoke 12th generation Uni-Q with MAT driver array for exceptional acoustic accuracy Refined tweeter gap damper tames resonances for improved detail Flexible Decoupling Chassis prevents unwanted vibrations for better clarity Enhanced crossover design and fine-tuned the signal path for pristine, clean sound 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. 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 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. Deep, agile bass Bass is a vital element of performance, and the low-frequency drivers of R Series have been engineered with acute care and precision. They are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This stiffness combined with the cone’s unique geometry reduces unwanted resonances and delivers the pistonic movement that makes these drivers time so well. The drivers’ magnet system creates a broad, uniform magnetic field, while the suspension reduces harmonic distortion for a clean, precise sound. The result is exceptionally deep and agile bass that reveals every last bit of detail and punch available in the deep.
