This is a Home Theatre installation project in Glenelg we have recently completed whereby the client wanted a dedicated theatre area built into an otherwise unused space within their home, however the room as you can see is not a what you would call a typical theatre area and had some intricacies with the raked ceiling, the overall layout of the room, and limited to no ceiling space to run cables. We ended up finding a way by utilising the base of the hand rail to conceal the cables. 

Epson TW8200 
4 x Niles In Ceiling speakers 
Elite Screens Cinegray fixed frame 
Yamaha Front floorstanding speakers and centre
Yamaha Amplifier set to 7.1 which will be modified to suit Dolby Atmos with a receiver upgrade shortly
Niles 10″ Sub 
Overall with the layout of this room it turned out to be quite amazing with directional speakers due to the ceiling facing right at the seating, excellent acoustics and sound production, and made great use of a small space.
