With the layout in mind, my next goal was sound isolation. Seeing as the Soundproofing Company is a great resource for folks here, i called them up and got some more info and purchased materials.
The plan is to set the outside walls about 1" off the concrete and frame 16" O.C. to an inch or so below the joists. I used IB-3 clips at 48" c-c to build an isolated frame around the room. For existing walls, i built a second wall and used IB-3 clips to isolate the framing. All walls in the open concept area are built using decoupled framing techniques. Ceilings were planned to be 1B-1 clips and channel. Double drywall (5/8") with green glue was to be used. From all I read this was the best bang for the buck sound isolation strategy.
Pulled the needed permits and off to the lumberyard!
Green treated lumber for the baseplate, normal studs for the walls, and an extra glulam beam to stick under the living room area in case I ever wanted to put a large fireplace in. The beam will provide the extra support for the potential weight of a stone fireplace. Framing went ok, I'm not a professional and a few of my walls were a little out of square.
Recessed lights, ceiling Atmos speakers, and HVAC was to each have a box built to control sound as well. This was my least favorite part of this project. I ended up "cheating" and only using 3/4" MDF to build the boxes with no second layer and green glue. Too many #$%^ boxes!
There are 12 can lights, 4 ceiling registers, two cold air returns, 4 Atmos speakers, and two side surround speakers in the blasted boxes. Of course I screwed up the measurements and made all the boxes too deep. So after having assembled, screwed, and glued, i had to go back to the table saw and cut them down 1". So advice to anyone, double check your measurements and remember you have to have a way to hold the boxes in place with 1"x 2"s on the sides in each joist bay. Mine got a little tight and probably is short circuiting a little of the sound isolation.
Electrical wire was run everywhere. 12/2 to the outlets, 14/3 and 14/4 to the lights/switches. CAT6 to anywhere I thought it might be needed someday. 12 Ga wire to the sub locations (future BOSS), front three speakers. 14 Ga wire to the surrounds and Atmos speakers. 1 1/2" Conduit ran to the projector location and behind the screen wall for future pulling of HDMI cables. RG6 to a few locations as well for TV and/or Sat. Care was taken to keep good separation between 120v wire and low voltage wire.
