12th-Generation Uni-Q Driver Array, 5.5-Inch Woofers, Shadow Flare Technology, and Flexible Ports Fuel KEF R5: Tower Loudspeaker Has Space-Friendly Footprint and Gorgeous Looks

Visually, color-toned aesthetics – whereby the speaker's domes, drivers, feet, spike, and logo are matched to the finish – immediately draw your eyes to the KEF R5 tower loudspeaker. But what will really capture your attention is how well this 42.2 x 10.7 x 13.5-inch (HWD) floorstander conveys musical information such as detail, tones, textures, dynamics, and soundstaging. Ideal for users with smaller-to-medium-sized spaces or who simply don't need the largesse (or added expense) of a bigger tower, R5 shares the exact same acoustic and technological DNA of the R Series flagship R11 while scaling back on dimensions and number of woofers.

The 12th generation of the renowned KEF Uni-Q driver bundling a one-inch vented aluminum-dome tweeter with a five-inch aluminum-cone midrange – leads the parade of innovations inside R5. Revised and improved, the Uni-Q boasts a redesigned midrange motor system that arrives courtesy of KEF's in-house simulation and analysis tools. Featuring a shaped and undercut pole as well as symmetrical aluminum demodulation rings that combine to significantly reduce the inductance in the lower midrange, the assembly lessens distortion and enhances imaging.

Equally effective and savvy, R5's Shadow Flare – a forward-thinking method of diminishing cabinet diffraction – visually functions a trim ring while functionally serving as a surface that extends the Uni-Q waveguide effect. Hence, in R5, the tweeter no longer has line of sight of the cabinet edges, thus creating a shadow region at the points where the potential for diffraction remains highest, minimizing the acoustic impact to negligible levels. In sum, the Shadow Flare greatly assists the reproduction of subtle cues and nuances in your favorite recordings.

When it comes to the low end, R5 doesn't blink. Two dedicated, 5.5-inch drivers with a redesigned magnet system provide deep, taut, punchy, and soulful low bass. Each woofer is built using a two-part structure, whereby a shallow concave aluminum skin sits atop a paper cone. The stiffness – combined with the cone's unique geometry – reduces additional resonances and delivers the pistonic movement that account for superb timing. Credit also goes to R5's flexible ports. Molded via computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence all the while the walls prevent longitudinal resonances from coloring the midrange.

Now, to those luxurious cabinets. They abide by acoustic principles that put the spotlight on sonics. Constrained Layer Damping bracing (in which the internal braces are joined to the panels by a lossy interface) helps dissipate unwanted vibrations. In addition, a revised bracing layout furthers the creation of an inert platform that allows the drivers to operate at an optimal level.

A fantastic performer in both two-channel and home-theater systems, R5 knows the ins and outs of music and movies as well as KEF and its six-decade-plus history knows speaker fundamentals. 100% Music Direct Satisfaction Guaranteed.
