About The KEF R7 Meta Speakers
The mid-sized 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.
Whether in stereo for music or in a home theatre set up the R Series makes exceptional acoustic performance more accessible. Now with the ground breaking Metamaterial Absorption Technology, the R Series reveals exquisite detail and incredible insight: truly an experience to savour.
Born From The Reference: Since 1961, KEF's quest to reproduce immaculate sound has led to many acoustic innovations. The Reference is a case in point. Distilling decades of experience into an acoustic performance that is nothing short of exceptional, it is a design that continually sets the benchmark for loudspeakers and sound reproduction. Now the latest technological innovations have also made their way into the R Series.
Metamaterial Absorption Technology: At the heart of the R Series is Metamaterial Absorption Technology (MAT™). MAT™ is a highly complex maze-like structure that absorbs 99% of the unwanted noise from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
Uni-Q® Sit Anywhere, Hear Every Detail: A 12th generation Uni-Q® driver array with MAT™ is found in all models of the R Series. Uni-Q® acts as a single point source to disperse sound more evenly through the room. The result is the elimination of the limited 'sweet spot', therefore allowing everybody, wherever in the room they may be, to experience and enjoy the same natural, detailed sound.
Performance Redefined: The R Series is engineered to be acoustically exceptional. Every element of the design has been precisely tuned to deliver more detail and deeper insight, recreating the exhilaration of hearing an original music performance, with all the emotion and nuance that goes with it.
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: You 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.
Beautiful by Design: Driven purely by acoustics, KEF believe there is a certain beauty even to the internal engineering fixings. The R Series has been created to be beautiful on the outside, and these finely tuned workings are protected behind a minimal exterior designed to fit seamlessly and elegantly into any interior scheme, whether traditional, modern or contemporary.
Dedicated Microfibre Grilles: The R Series has been engineered to perform with or without grilles. The dedicated microfibre grilles are crafted from multiple layers of material and have a suede-like feel. With 1801 precision-cut holes for each driver, performance is ensured even when the drivers are covered. The magnetic fixings provide a secure and precise fit, in keeping with the clean styling of the R Series.
