Room Demensions, am I in trouble?

Hello people,

I'm moving into my first house and we have a room for a theater!!! The only part that looks like it could be a problem is the room demensions. The room is 12'W X14'L X8'H.

I will also be using this room for music(very important to me!!!). I have Thiel 2.3's for mains with a Thiel center and I have Energy Veritas 2.2's for rears. I also have a Sunfire True Sub. the TV is a Sony 43" RPTV (18" deep). The room has hardwood floors and two windows (Not casting day light on the TV screen.)

I want the room to fit 4 viewers (5 max). Its gonna get tight in there! I would like feedback from others who have been through this same situation. Please give me your advice, and recommendations. I'm not interested in feedback on my equipment, because I'm not buying any new stuff right now (Can you say mortgage payments in Northern California!!!)

Thanks
