The room is square so I know I will need some bass traps in the corners and I know I will need to treat the first reflection point. on the back wall, how do you determine location and size of treatment. Same question for the ceiling.
I still haven't determined if I plan to cover in fabric the first 6ft of the room with velvet for the screen reflection.
I like building things so it's why I prefer to go the DIY route.....plus to lower my cost and customize to my desire.
Anyhow, I appreciate the opinions for all you experts cause I know my limitations and smart enough to ask more knowledge people than me. Help me learn in the process.
The area behind your screen can use some OC703 board, wrapped in cheap burlap just to contain the dust, or what ever material fabric is cheap.
Prioritize all your flat surfaces and corners, each will require the right treatment to achieve the result you are looking for.
Example, i have two flat surface area's that have a slap echo/flutter echo. Its not i high priority, like a first reflecton point, its well out of the way, so some wood diffusers will break up the parallel surfaces and reduce any colour produced by erant sounds.
You will hear opinions also that first reflection absorbers create a blackhole effect that is very unatural. 100% true.......if you fail to complete proper treatment of the rest of the room. If you continue to address all these surfaces that ADD reflections, and their own signature sound, you have removed the room and now hear the music/movies.
But, dont be a follower, dont listen to me or anyone else and just DO. Get involved, add and subtract as you see fit, listen listen and listen some more. The worst advice is to do it cause i said so.
