Yes the rooms have different ceiling heights. They sounded great in a standard rectangle room with wall to wall carpeting and 9' ceiling. They are now in a much more open room with ceiling height going from 10' to around 14'(shed roof). As well the side wall has many large floor to ceiling windows. Basically, the room is a large open family room to kitchen with hardwood floors, giant glass windows, and tall sloping ceiling. The system just sounds really really thin. As well, the Druids are only about a foot from the rear wall(cannot move out). I am thinking about changing speakers to something like the Gradient revolutions that seem to work better in poor rooms (but would like to fix the problem with the druids if i can).
