R700 Black Edition
‘Well, I’m back
I’m back in black’
So sang Australian rock band, AC/DC years ago.
No other colour inspires mystery, power and glamour as black does.
For a short period starting Dec 1, 2017, you can choose the powerful, pure sounds of the R-Series in a Black Edition pair of floorstanders. Black Uni-Q drivers against black cabinets.
Just 500 numbered pairs of this special edition are on offer - some of the finest speaker technology packaged in cool mysterious black - making a statement that can only come from KEF.
Features
Amazingly fast and clean mid-range response. Startlingly pure high frequencies. All operating as a single perfectly integrated voice to deliver sweet, accurate sounds of unprecedented clarity.
KEF Uni-Q driver array is nothing short of a masterpiece. Unlike conventional speakers, the mid-range cones are rigid magnesium/aluminum constructions that reduce breakup problems. The new mid-range Z-flex surround smoothes the tweeter transition to the front baffle, which results in undistorted high frequencies.
Large voice coils increase power handling and dynamics, reducing distortion and delivering exceptional vocal clarity.
Venting the tweeters reduces pressure behind the dome, increasing midrange bandwidth and lowering distortion. Upper registers are articulated with flawless precision. KEF’s tangerine waveguide helps disperse higher frequencies evenly across a wider angle to flood the room with a sophisticated, refreshingly natural sound field.
