New room, very small .Speaker Placement???

I am moving in a couple of months to our new home. It will actually be ours but the room I have available for my stereo is a 10'x11' room. What is interesting about this space is that there are two full parrallel walls and there are two parrallel 3 and 1/2 foot walls parrallel which the top of the area of the short walls is open space of the top floor of the house.The ceiling is 8 feet high. Any reccomendatuions on speaker placement would be greatly appreciated. One source says to use the full walls for the back of speakers and behind me and another source says to place the speakers in front of the 3 and 1/2 foot walls with my listening position at the opposite 3 and 1/2 foot wall. I'm confused. Do I go for the reinforcement of the full walls behind the speakers or on the open 3 and 1/2 foot walls? Remember my room is only 11x10 feet. The open short partial parrallel walls are 10 feet apart and the full walls are 11 feet apart. HELP!!!!!!!!
I should mention my speakers are Hales Transcendence 5's and my amp and preamp are Pass Labs. The Hales are large and I am thinking I may be able to take advantage some how of the 3 and 1/2 foot parrallel walls. Please advise.
Thanks.
