I've always found the Odd Dimensions Placement, advocated by Richard Vandersteen, to work well in every application. In my current listening space, the speakers are located 1/3 of the room width from the side walls and 1/5 of the room length from the front of the speakers to the front wall. Toe-in axes intersect approximately 4-5 feet behind listening position. Acoustical panels on wall behind listening position was money well spent.
