Axiom Home Page Forums General Discussion Advice from Axiom Owners SPL set-up and Speaker Questions

I have been playing around with my speaker set-up and using my SPL meter alot. When I use this thing to adjust the spreaker levels, shoud I be pointing it at each speaker from my most used listening position, or leave it pointing straight forward towards the TV?

Also, I am considering getting a couple more speakers to make a 7.1 set-up. They would be for the back. I was looking at getting the M22's and stands, or the M50's. That works out to be around the same price. Any thoughts?
