Buckeyefan 1,
2 of the walls are studed over the concret basement walls. I have insulation in all the walls and there is sheetrock under the paneling for support. I don't have any insulation in the ceiling. The subs more than easily power the room. I would like to get another amp mainly due to space issues on my rack and the 5-channel I have now isn't enough of an improvment to use for the main channels. Someday, I will upgrade to more than likely an ATI amp for the main channels and just a good 2-channel amp for the subs. I am also looking into acousitc treatments, although the room sounds very good now. With the front wall carpeted, it absorbs a lot of the reflections from the front, and the reflections in the back of the room, I think, strengthen the disperse sound field. My first project is to counterskink more DVD shelving into the wall. I have DVDs in many different locations all over the basement. I would like to get them all into the HT room if possible. I will just build the racks using 1 X 6 pine boards with a 1/4 oak backing, then countersink the shelves in the wall so they only protrude an inch or two. I am just hoping I have enough space on the left side of the room to fit all the movies I have. I have no idea how many I own now as I stopped tracking them at about 1300 and that was a couple years back, but I don't buy movies as often now. I wish my room looked more theater like, as some members here do, but in the dark I guess it really doesn't matter much.
