From the Forums: DIY 'Maple' Home Cinema
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).
