Actually, my setup right now is a little weird. I originally bought the M22's bookshelf with stands for L/R for a projector room, but used them in my TV room instead. Then I bought the on-wall setup for the TV room for aesthetics. After doing much comparison, I decided I liked the sound from the boxy speakers better, so now I have both the M22 bookshelf on stands and the on-wall M22's mounted directly over them in a vertical fashion for a nice sound (and an EP350). I no longer run them large, but when I had just the M22 on-wall, with and with-out the EP350, the sound was fuller if I ran them as large. Now with the addition of the bookshelf M22, running them as large isn't necessary. I intend to replace the on-wall with boxy M2's and mount the M22 that are on stands on the wall, someday. The on-walls provide a better wall-of-sound than the boxy ones do. I'm hoping that the addition of the boxy M2's will do the same. The on-walls will then probably be mounted on the back wall.
