Hello, All
I have the opportunity to use the space above my current basement ceiling for wall-to-wall bass trapping and first reflection absorption. My room is roughly rectangular measuring 22' wide x 17' deep and a little less than 8' high. Above the drywall ceiling is a 2' space under my living room floor. My thought was to remove the sheet-rock and install 6"-12" of 703 (12" around the perimeter) leaving a nice dead space between the insulation and the floor above. The 703 would be sitting on studs spaced about 16" apart center to center. I also have a ton of low density fiberglass rolls I bought for next to nothing if this installation would benefit from the "dead space" being filled up with this stuff. My goal is to wind up with an over-damped (by normal listening room standards) room. Please share your thoughts.
I am willing to paint the studs flat black and use either burlap or thin polyester fabric either above or below the studs with the 703 sheets sitting on top of them. An alternate could be to thin out some flat black latex paint and spray the 703 on the exposed surfaces. Would this change the absorption of the 703 at higher frequencies and could this be desirable? Might this also keep the glass fibers in place?
I have treated the other first reflection points but still have plenty of ringing using the hand-clap test. BTW, this room is a dedicated space and I will be using a JVC XP-A1010 ambiance processor with 4-8 ambiance speakers. My mains are Dunlavy SC-Vs, so there is need for plenty of bass-trapping. The untreated walls are mostly drywall construction, but one short will is concrete block. I have the option of using Dirac Live also.
Thanks for any and all advice or comments,
