From the Forums: DIY 'Maple' Home Cinema

Cornish cream of the crop

  • Our member burtonpark has built themselves a very swanky home cinema down in the depths of Cornwall.
    The choice of AV equipment and the acoustic treatment and overall design is all theirs and as was the installation of the kit and wiring but, sensibly, he supervised a couple of carpenter/builders for construction. The room measures 7.3m x 4.4m x 2.4m (LxWxH).

    The screen is an acoustically transparent Screen Research 2.35:1 cinemascope screen with electric masking, The JVC HD950 projector has an anamorphic lens sat on a custom ceiling bracket which burtonpark designed.
    The RBH Signature speakers are serial no 1, of a limited edition of 100, and are finished in maple. The left and right pair are full range with additional amplification for the lower sub section. There is a matching centre speaker behind the screen. The L/R and Sub speakers sit on a raised and curved front stage which is filled with sand (when in Cornwall and all that).
    The acoustic treatments in the room include RPG flutterfree maple (side walls also helmholtz cavities), RPG Twin BAD Diffuser Panels front ceiling, behind the black fabric walls are Six Modex BASS Absorbers located behind the screen and the front left and right walls and the rear wall.
    The six cinema seats are fully electrically reclining and the rear seats sit on a raised platform which has butt-kickers which he has not yet got around to connecting.
