KEF R3 Meta Speakers
The KEF R3 Meta redefines bookshelf speakers’ performance. Sharing the same drivers as the range-topping R11 Meta, the R3 Meta is a true three-way design. It has a 12th generation Uni-Q® driver array with MAT™ and a powerful 6.5” hybrid aluminium bass driver that pushes performance to new extremes.
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.
