I was looking on my new Digital Video Essentails disc, and it showed a diagram of what would be good building materials for a wall, though I haven't yet been able to find any more detail on it. I'm finishing a room in my basement for a home theater setup. It's a small room, but hopefully should work. It's a room that's about 10' wide, 17' long, and 8' high. The front and back walls have already been sheetrocked. I'm kind of confused what I'm seeing here. So, questions are: 1. which side of this diagram is the front and which is the side that I don't see? 2. With the soundcore, does it matter if I only have that on the two side walls, and not the front and back since they're already done? Plus, the right side wall will have doorway spaces in it, as well as a big space where I'm building a shelf that has rear access on the other side of the wall. So there's not much drywall that will be on the right side, is what I'm saying. 3. I'm actually not sure what I'm seeing with the staggered stud wall there. Am I supposed to leave the zigzag spaces there like that, or is that just showing it pulled apart? 4. What about insulation? Is there anything about filling those with insulation?
