"How big is your room?"

It is a very acoustically unideal loft that is 15' X 30' and is open over a rail on 2 sides - and we only use 1/2 of it (about 15' X 15') for the home theater - and to make matters worse, we have the TV in the corner because we really like the view out the windows at the one closed end. So the functional area is essentially a 15' square that is open on 3 sides with a TV in the corner, windows on the wall to the right of the TV, loft rail and open space to the left of the TV and seating on the other two sides of the square. The surround speakers are in the corners (cheated a little further back) and the 6th speaker would go diagonally across the square on the opposite side of the room from the TV if I were to add it. I'm technologically challenged so I can't offer up a good diagram on here like many have done - so I hope this helps...
