IMO, if it was awful - regardless of the room - it was a poor set-up. I say this, having successfully voiced 800-1000 systems to all kinds of rooms (including a number of shows where we were awarded Best Sound of Show) in my career.
It was definitely a poor set up but the gear was in the only position that it could be due to the odd shape of the room and the Wife.
It's a friend of mine that lived here in the Twin Cities and his system sounded great until he moved to New Mexico. No amount of tinkering will help his situation until he gets a new house, a new wife or a divorce.
