I find your setup interesting. I planned on using M22's as surrounds (primarily listen to music). As I don't have any room behind me I was advised to place facing one another on side walls so they are directed over the middle of the couch. I wonder if I'd be better putting them at the back wall and toeing them in a bit. Based on where I'm seated one speaker will be about3 feet away from me and the other about 5. My processor can compensate for the distance. What do you think?
