KEF R300 Bookshelf Speakers

KEF

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.

  • 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.

  • POWER

    Dynamic, uncompressed and undistorted bass of heart pounding clarity envelops you, striking deep emotional chords. Your soul will awaken. And the earth will move.

    BASS DRIVER

    Massive, vented magnet assemblies and large aluminum voice coils drive the lightweight yet stiff, strong hybrid cones. Bass output is faster, cleaner and more accurate. Satin anodised elements contribute to the unit’s elegance, while the diameter of the trim ring accentuates a visual sophistication that belies the speaker’s awesome power.

    PRECISION

    Designed from the ground up, the R series is a towering leap forward that creates a new dimension in sonic authenticity.

    The geometry and bracing of the enclosure optimises vibrational behavior, reducing secondary radiation from cabinet walls for a cleaner sound. Damping panels further minimize cabinet resonance and colouration.

    Front baffles are clean with no visible screws. Grilles are fixed magnetically. Available in real Walnut and Rosewood veneers, or highly polished Piano Black, the R Series complements the home as much as it respects the music.
