R900 Floorstanding Speaker
With twin 8-inch LF drivers positioned perfectly either side of the remarkably sweet and accurate latest generation Uni-Q driver array, the KEF R900 ensures an incredible scale and depth. Upper registers are articulated with flawless precision, whilst the bass drivers maintain authoritative control over the LF - providing undistorted, earth moving realism and accuracy that will awaken your very soul.
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.
