Ive got low voltage, electric, and HVAC done. About done with insulation, should be by the weekend. Also have sheets of 5/8" OSB sitting here ready to go up. Dry wallers took measurements yesterday and can be ready at 2 days notice. Ive opted for a 7.2 design, but all areas are conduit'd back to the rack if i want to expand to 19.12 at any point.
Currently Im questing my soundproofing and would like opinions. All the walls and soffits are connected to the joists with DC04 clips. Behind the studs is 1" rigid, so im definitely 1" from the foundation. My goal is reduce footfall, but more importantly is to keep the theater noise in, specifically the .2 portions of the setup. My original plan was to put hat channel on the walls, bottom and sides of soffit. Whisper clips+hat on the inner tray of the ceiling. Ive got R19 in the ceilings and most the soffits (1 soffit has a trunk run with no room for any), R13 on the walls. Then add 5/8" OSB + 2 loads of GG + 5/8" drywall on everything. I feel like the hat channel on the walls soffit is a waste with having the DC04s, but was thinking that for the small expense, it will decouple anything that the framers did wrong. I was also questioning the expense of the whisper clips and considering RSIC-V instead for a 1/3 of the cost.
