Тонколони KEF R3
The 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.
Uni-Q
The evolution of KEF’s Uni-Q driver reaches its 12th generation in the R Series. Using simulation and analysis tools KEF’s engineers have been able to dramatically reduce colouration by cutting resonance in the tiny gaps between Uni-Q’s elements. The result is purer and more precise sound with stronger imaging.
Shadow Flare
The 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.
