You need to rethink your priorities. If you are constrained by WAF or other issues, don't waste your money on expensive speakers to position as you describe. Your room is on the small side for floor standing speakers with ample bass extension. Combine that with placing them against the wall and you have a sonic nightmare in the works. You might do better with some very small monitors and a sub, but you will still be compromising performance with your choice of placement and room size.
