Well guys, it finally looks like I will have a 20x22 foot room that will be dedicated to HT and two channel. My main focus is to build a two channel rig that can serve as a temporary theater setup from time to time. Right now, I am less concerend about gear than I am about getting the room right. It will be carpeted wall to wall, but I will need to first build the walls and ceiling. All electrical in the room will be on a 20amp circuit and in-wall speakers will be used for all surround locations except for mains and center channel.
The questions I am looking at are should I use a certain type of drywall/insulation?
In a room of this size, is there any benefit to building the walls so that they are "staggered", alternating between 2x4's and 2x6 every 16"?
How about the ceiling, which is at 9 feet? Should I have one side at 9 feet and drop to 8 feet on the other?
I guess what I want to do is eliminate standing wave considerations and build the room in the best way possible for two channel, then set up the HT, letting the Pioneer correct anything that may be off on the HT side.
