I have a 7.1 AV 123 system. The problem is, in my infinite wisdom I ended up with RS 850's 750's, and 250's for the front, side, and rear. I originally wanted to put the 850's in the front and the 750's in the rear, with the 250's on the sides. My room layout ended up being a lil different than I expected and now I have two options. 250's in the rear, or 750's laid flat. I'm not sure which would be best to choose.. For size reference the 750's have 4 4" or so woofers and the 250's have 1. The location will be 8ft from the floor.

Any opinions?
