Hey guys,
I'm currently in beginning stages of designing my home theater in my basement. It will be in a 18x25x7.5 rectangular room. The room will contain 2-4 diy ~10cft 18" subs, ascend towers and center with RAAL and 4 surround speakers. Screen is 130" projector located somewhat off-center on 25' wall. I am very new when it comes to acoustical treatment, and I only have my research on a few forums to go off of.
My question really boils down if to using 1/8" sheetrock walls as a kind of panel absorber bass trap will benefit over just building normal walls and trying to bass trap inside the room. The 1/8" sheetrock walls will be at least 8" from the concrete/adjacent room walls with insulation filling the gap (but not touching the sheetrock). I can seal the cavities behind the wall airtight as well if needed.
I'll likely have enough room in the two back corners (where the subs will likely be located) to put some 30" fabric faced superchunk bass traps, and my low (7'5") ceiling will be fabric covered with insulation to help it "appear" taller acoustically. Also, behind my front screen/towers I could (if recommended) do a false fabric wall (or scatter plates if high/med absorption is too much) and put in a larger 2-3 ft deep superchunk trap by expanding into an unfinished bedroom ,only about 10ft of 25ft wall can be expanded though. So, this would result in a 10x3 section added onto a rectangular room, making it irregular shaped, so I'm unsure if it would hurt more than benefit or not. I have some primitive Microsoft paint drawings that I have attached, the first is the room layout, the second is the proposed walls/insulation trap design.
Any input is appreciated!
