Big Headache is right. His room sucks canal water. He is so close yet so far from maximum sound quality.
In order to get the maximum SQ out of a room like that IMHO I would add another couch and go for stadium seating. The more people, drinks and popcorn in a room, the better it sounds. I would consider a bar in the back with a Helmholtz Bass trap built in.
You're gonna have alot of fun in that room.
