That is one gorgeous system srobak! I really wish the wife would allow me to have floorstanders. Instead I'm stuck with RB-51's! I might look for some floorstanding speaker covers though to help my cause.
nezff, I can't place my RS-42's in the back wall because it's in the kitchen. My floor plan is open so the family room extends into this vacant space in front of the fireplace (where my pool table is going) and then the kitchen. It's about 30-45 feet long (I suck at gauging distances!)
