Couple questions about sealing off the room....
I am planning on fully insulating the wall, pink fluffy all around, and I also can put some studs horizontal to try and brace the wall against the adjacent cinderblock footing for the other part of the house, if it is needed. The entire closet is basically the space you see, 3 feet wide or so, with the steps declining to the theater, and then about 20 feet long. Plenty of room, but the two issues I am assuming I need to address is the door, and above the sheetrock where the closet opens to the shared drop ceiling. First the drop ceiling: There is no ceiling in the closet, so when I look up I can see where the sheetrock stops and there is an opening to the area above the drop ceiling on the other side of the baffle wall. Now this area isn't immediately shared with the theater as there is a wood footer that partitions the theater area drop ceiling from the rest of the basement. For this reason I don't know if it as big of an issue as otherwise it should be. All of the space above the drop ceiling in the theater is heavily insulated as well (between floor joists and then additional insulation that I put up in between the joists and the grid). Anyways the big questions are:
1) Do I need to seal this area off as good as I can?
2) Does it actually effectively make the "size" of the room bigger with that additional space I am gaining by leaving it open and therefore benefit the IB design?
Then the door to the room. I plan on running some gasketing all the way around the door to help with vibrations and such, but there will still be a gap at the bottom of the door and the floor. This door is a good 15 feet away from the theater area and is located in the small hallway off of the back of the theater. I can try and seal up the bottom gap if it is needed but once again:
3) Is sealing up the bottom of the door that important when it is that far away from the actual speaker (~10 feet)?
