R700 Floorstanding Speaker
The KEF R700 exudes sophistication, not only in its contemporary design and use of high quality real wood and piano high gloss finishes, but in its class-leading sonic reproduction. The three-way design makes music or movie sound tracks controlled, detailed and dynamic, whilst twin 6.5-inch aluminium bass drivers deliver a fast, controlled and authoritative low end.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.
