KEF R3 Bookshelf Speakers
The KEF R3's has an Uni-Q array design. It uses a 25mm aluminium dome tweeter with a 12.5cm aluminium midrange unit and features a host of detail refinements to the motor assembly, suspension and drive unit structure to reduce distortion and improve performance over earlier versions.
The overall build quality is terrific. The enclosure feels immensely rigid due to some clever bracing techniques that combine reinforcement with damping. On the outside, these speakers look classy and are finished beautifully. All the edges are crisp and the gloss finish on our black samples is lovely. The R3s are also available in gloss white and a more traditional walnut.
