    DESCRIPTION +

    The KEF R3 stand mount shares the same Uni-Q driver array as the range-topping R11 in a full range design that defies expectations.

    A true 3-way speaker the R3 has a powerful 165mm (6.5 in.) bass driver and a 125mm (5 in.) midrange driver with 25mm (1 in.) aluminium dome tweeter Uni-Q array that pushes performance to new extremes.

    FEATURES +

    Derived directly from the Reference Series, the Shadow Flare is an innovative method of reducing harmful cabinet diffraction for delicate high-frequencies. Shadow Flare is a carefully profiled transition surface which 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. The result is vastly improved fine detail, particularly when it comes to the subtle nuances of plucked strings and other percussive sounds.

    CABINET BRACING

    A solid platform is imperative for great sound. The new R Series benefits from Constrained layer damping. This system utilises internal braces joined by a ‘lossy’ interface and is highly effective at dissipating unwanted vibrations that would otherwise artificially change the sound and music.

    FLEXIBLE PORT TECHNOLOGY

    When it comes to generating deep, articulate bass, port design is crucial. The ports in R Series 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.

     

    BEAUTIFUL BY DESIGN

    Great design is timeless. KEF’s product designers seek to create deceptively simple, elegant loudspeakers. But form follows function. So whilst R Series is driven by acoustics, all visible engineering fixings have been artfully concealed so all the listener sees is a beautiful and simple exterior. Conceived to be at home anywhere, the R Series comes in a choice of two sleek gloss finishes or a classic wood veneer. These finishes go deeper than just a base colour: each speaker benefits from KEF’s tone-on-tone approach where tweeter dome, driver cones, feet, spikes and KEF logo are colour-matched to the finish.
    MICROFIBRE GRILLES
    The R Series has been created to sound at its best with or without grilles. This microfibre design is a first for KEF and resulted in a design that not only looks beautiful but has negligible effect on sound performance. All of the grilles are hand crafted and compressed with heated pressure from thirteen layers of composite material. The grilles continue the tone-on-tone approach: grey for the white cabinet, brown for the walnut, and black for the black. The grilles edges are burnished in a similar way to fine leather goods and the overall effect is almost suede-like.
