Question then... I had not thought of having a stage...Is there something important about having a stage? I was just going to have a audio transparent curtain to the sides and make a black moveable frame to suit the image. This is going to involve a friend of mine who is big into making things happen. The masking is quite interesting and that is my next BIG port of call.
I was concerned that my questions were in danger of a hijacking. I am very happy to open up a separate thread and invite people to contribute. I dont want to detract from your home theatre project thread. SHould I open up a new thread - my only concern with this was to stop the high degree of 'chaff' that you sometimes get on these forums. Also I feel as if I am being somewhat overbearing in my questions and I guess you have your own ship to sail. Mind you I could also match you for gardens and John Deere's - although my garden tractor is like this!!! I steers from the rear.. I used to have a wonderful Wheel Horse but that died. I need the front cutter deck to get under the many plants my wife has planted around the edges of the lawn!! Let me know how to play this forum
Regards from the Spring Sunshine!
My build is above the garage I am not calling it a bonus room because I designed the house (along with builder and architect) for that area to be a theater. I lowered the roof of the workshop to accommodate the front of the theater to be 12” lower than the rear which is on level with the rest of the upstairs. In the first few pages of my thread you will see I used acoustical caulk in all of the cracks and holes between the garage and the theater. We also installed a second subfloor of ¾” Tung & Grove OSB using green glue and again every crack had acoustical caulk. The ceiling of the garage was spray foam and I had electrician put putty pads on the light fixtures and outlet for the openers. If there was living space down there I would have used R19 vise the spray foam and did a DW/GG/DW on the ceiling of that space with IB-1 clips.
caulk in garage
you can see the caulk here
Here you can see the green glue on the 3/4" T&G and also the caulk on orginal sub floor and second sub floor going in.
we also put OSB on the 2x12 used to lower the work shop ceiling
pile of T&G
caulk on second sub floor
I did not take picture of putty pad in garage ceiling but here is one in the wall between theater and billiard room
I will have to see if I can find it. It may have been in the show me your completed room thread and the person did not have his build linked in his name
Did you use acoustic caulk on all the walls too, or just the ceiling joists?

Your build thread has been a pleasure to rewad through. I love ground up whole house builds! Thanks for all the detailed pics and information. You're situation is a goal of mine (5 acres open field, Nice house with projects, etc...) I'm a few years/decade away, so no rush ^_^. Keep the updates rolling!
You can just make out the caulk between the sheets of drywall at the bottom of this picture
I also caulked every wire intrusion
Bottom line: if there was a hole or seem or crack I put caulk in it! Did I need go to this extreme I don’t know but results speak for them self. I have a totally sealed room and the weakest link is the door. I am really pleased with my sound proofing. There is some debate going on over on the sound proofing sticky about the use of caulk check it out.
I have a 2nd floor build with HVAC in attic but same principle. Here are two of my 6”supply lines and my 10” return line
Bring the return in the center I have a 12"x24" soffit in the rear I used as my muffler. I used 1 1/2" duct liner in the soffit.
here you see how I split the soffit with OSB to form the dead vent making a T from the return to run the dead vent in both directions
here is the dead vent lined with the duct liner I have a 6x16" return one each end.
with the supplies you bring them into the soffit
I had two supplies on each side the soffit in front had not been hung yet
front snaked around toward the back the center snaked from the rear
stuff with pink stuff
hang OSB cut hole
repeat for drywall
