I have a decent sized basement and I want to use part of it as a cinema room. I'd welcome comments and feedback.
The space I plan to use is rectangular and measures 9 x 5 metres with a ceiling height of 2.7 metres. The basement is clean and dry. I'm hoping to achieve a decent result without spending an arm and a leg.
The walls are rendered and painted concrete. Of the 2 long sides of the room one is essentially open with 2 arches and a central pillar (which lead off to another space). The other long side is approximately half solid wall and the other half is an archway. At one end of the room is a solid wall without any openings. This is where I'm planning to position the screen. At the remaining end of the room about 2/3rds is solid wall, with an archway in the remainder. Obviously, at the moment the room is very hard acoustically. Lots of echoes. There is a number of socket outlets in the room.
I'm thinking that I need to install some heavy floor to ceiling curtains along both long sides of the room and cover most of the floor with large rugs. I'd need to buy the curtains and rails, but I already have a variety of large rugs for the floor. I'm considering not having any dedicated seating (to avoid the expense) but to simply use large cushions instead. If that proves unsatisfactory then I could buy a couple of day-beds.
The cinema equipment would be a projector mounted either on the ceiling, or on the end wall. The audio would be provided by a home theatre system that I already have. I'd need to buy the projector, so I'd grateful for opinions about projectors and things to look out for.
What do you think? What have I missed?
