OK - I can get 2-M22's for the fronts, 2-M2's for the rear and the VP100 for the center and still stay in my budget.

Being you suggested to get a M2 for the center leaves me to wonder if the VP100 will not match with the M22's?

Also when I started to look at speakers a salesman told me about the RTi's from Polk and that they are timbre matched. How are the Axiom speakers with each other?

When I advance to the 7.1 setup I can get me 2 more QS4's for the rears.
