I currently have a React 2.1 ambient light rejecting screen. My next upgrade was originally planned to be to XTZ Cinema LCR. However, the increased size of the speakers would mean either raising the height of the screen, or replacing the unit below to something smaller. So it got me thinking; speakers behind the screen, with AT material. This causes problems for me however: 1) The door will need covering with Devore, especially if I lose my React screen, for something like Filmex. I sit pretty close so would need a material which won't show its structure. Do you think if I cover the side walls by 1m (just over the width of the door), and the ceiling out to 0.6m (spot lights prevent any more), this will cut down enough on reflections enough to allow a screen such as Filmex? Something like this. The walls are flat matt Dulux grey steel 2, celings 3. I'd paint a darker grey too I think. I'm likely going to do this and the devore covering regardless of screen and speakers. 2) the room is small and the door is right up to the screen wall, so I don't have the option of a false/baffle wall. This raises questions over the feasibility of placing speakers in the wall, which is 100mm concrete block, though is non load bearing. Can openings be cut without affecting the integrity of the wall to support itself? The wall in question is is between the utility and dining room - utility joists run as per dining room. If this is feasible, would something like M&K IW-95 be of similar spec/performance as the XTZ? I know that is subjective, but just after a ball park as I've demo'd the XTZ and would be after something of similar quality. Any advice appreciated - thanks.
