I have a small room for my home theatre, it's 17 by 11

i have the following setup:

M22Ti front
VP150 center
M3Ti rear
EP125 sub

I find the room is not large enough for the sound to be all that good. In movies, the front speakers don't seam too well together. The sub does not disperse sound all over. the way i have it now is:

M22's about 5 inches from the walls in the front corners on Atlantis SBF20 stands
VP150 above my screen
M3's about a foot from the walls in the back on Atlantis SBF24 stands.
EP125 in the front left, in front of the M22, with the driver facing sideways, settings are phase at 0 degrees and EQ to audio.

thanks for the suggestions!
