we wife and i are having a house built and i'm planning a theater in the bsmt. the construction won't be for at least a year after the home is done (time for the bsmt to dry out and house to settle). however i'm laying out the future theater since i have to figure out where the bathroom is going to be located (having the builder pre-plumb for the bathroom). just didn't want to have to work around the bathroom later. i've done a lot of reading on this site and am finding that the more i read the more confused i am becoming. hopefully i'll be able to sort thru all of it and apply the necessary techniques to our theater. the room i'm planning will be approx 23x14. 3 of the walls will be adjacent to the concrete block, the 4th will be next to an open play area. i've read about using 2x6 headers/footers to stagger the 2x4 studs. should the 3 walls next to the concrete be 2x6's or can i just use 2x4 headers/footers. what about the ceiling. i plan on adding a set of joists to the theater room in order to separate the theater from the main floor joists of the 1st floor. can i use 2x4's to span the 14' width. lastly, regarding the 4th wall, instead of 2x6's, what about using 2x8's for the header/footer. is this overkill. i figure with the 2x8's & using 2x4 studs, there would be a 1/2" gap between the 2 rows of studs. i figure this would help with noise reduction. i have many more questions but just wanted to get a starting point for the basic layout. thanks for any assistance.
