KEF R7 Meta - Three-way Floorstanding Speakers

The R7 Meta is the mid-sized floorstander in KEF's R Series, offering power and flexibility in equal measure. 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 deep, accurate and dynamic bass. the R7 Meta comfortably outperforms expectations.

Decades of experience and KEFs unbridled passion for music come together in the R Series, combining innovations from the Reference Series with bespoke technologies to help deliver more detail, deeper insight and greater excitement.

Upgraded Uni-Q® driver array for improved clarity and accuracy

KEF's patented Uni-Q driver technology places the R7 Meta's 1" vented aluminium dome tweeter in the acoustic centre of the 5" aluminium midrange driver. This arrangement allows the sound from the two drivers to reach our ears at the same time, resulting in more natural sound. Uni-Q technology is now in its 12th generation, and the engineers at KEF have designed this version to reduce distortion caused by several factors, as well as optimising it to take full advantage of the MAT absorber. 

Revolutionary MAT technology improves performance

This speaker gets the "Meta" part of its name from KEF's innovative Metamaterial Absorption Technology (MAT) — a highly complex, maze-like structure that absorbs unwanted sound waves coming from the rear of the tweeter. The resulting sound is clearer, purer, and more detailed.

Shadow Flare

Derived directly from the Reference Series, the Shadow Flare is an innovative method of reducing harmful cabinet diffraction and one that allows the wonderful Uni-Q to work at its highest level. Shadow Flare is more than just a trim ring. It is a precision designed surface that extends the waveguide effect of Uni-Q. The tweeter no longer has line of sight of the cabinet edges, creating a ‘shadow region’ at the points where the potential for diffraction is highest, minimising the acoustic impact to negligible levels. The result is improved clarity, particularly when it comes to the subtle nuances of plucked strings and other percussive sounds

Deep, agile bass

To maximise bass performance in the new R7 Meta, the dedicated low-frequency drivers 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 additional resonances while greater driver excursion allows for tight, deep, controlled bass. The result is tight, agile bass that conveys all the power and emotion in your music.

Unique Cabinet bracing

All the cabinets in the new R Series benefit from Constrained Layer Damping bracing. Originally developed for the multiple award-winning LS50, this system utilises internal braces joined to the panels by a lossy interface rather than being adhered to it rigidly. This approach is highly effective at dissipating unwanted vibrations. A new internal bracing layout works alongside Constrained Layer Damping to create an incredibly inert platform from which the drive units can work their magic, enabling the R7 Meta to deliver music as it is supposed to sound, without any unwanted extras.

Flexible port technology

When it comes to generating deep, articulate bass, port design is a vital element. The ports in the R7 Meta are precisely positioned and feature innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence, while the flexible port walls prevent longitudinal resonances from colouring the midrange. The result is not only better bass, but cleaner sound further up the frequency range in the vital lower midrange area

Beautiful by design

Great design is timeless. KEF’s designers seek to create deceptively simple, elegant loudspeakers. While the drive unit arrangement is rightfully driven by acoustic, rather than aesthetic considerations, each loudspeaker is visually appealing without resorting to brash styling.

Understated design is complemented by carefully selected finishes. Conceived to be at home in either traditional or modern interiors, the R7 Meta comes in a choice of three exceptionally sleek gloss finishes or a classic walnut wood veneer. These finishes go deeper than just a base colour. Each speaker benefits from KEF’s tone-on-tone approach to design where the tweeter dome, driver cones, feet, spikes and KEF logo are tone matched to the finish.

Microfibre Grilles

The R Series was created to sound its best with or without grilles. The microfibre grille design is a first for KEF and not only looks beautiful but has a negligible effect on performance. They continue the tone-on-tone approach to match the various cabinet finishes and the edges are burnished for a suede-like effect.
