My room is 15'L X 13'W X 7.5'H At first I was thinking of leaving my HTR open at the back, but I think I've now decided to close it in with double doors on the side to give it that open feel when I want it. I think I want 7.1 surround. Does that make sense in a room this size? I really like the Yamaha HTR-5990 and I have my eye on some Adire kits that would provide 5 of the 7 speakers leaving me to timbre match the sides that would round out the 7.1. I'm thinking of making my own sonosub out of a 15" or 18" Adire sub and plate amp. I have no idea what projector yet. I have a cheap LG DVD player right now but from what I read I should probably upgrade that as well. I'm also planning on putting two rows of seating in the room with the back one elevated. Both will have Buttshakers in them. Does anyone have some general advice for me?
