R300 Bookshelf Speaker

Featuring the all-new Uni-Q driver array and a 6.5-inch LF bass driver, the three-way KEF R300 lacks for nothing. Its stylishly uncluttered appearance beautifully complements the fast and clean mid-range response, along with accurate and clean low-end frequencies. With dynamic, uncompressed and undistorted LF performance, the R Series R300 provides a clarity and realism many strive to emulate but few achieve.

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.
