HEY EVERYONE!! I'm trying to figure out which configuration to go with 5.1, 6.1, 7.1, and I think there is a 7.2? I'm fixing to build and my room will be 18X22X10. I want the system that would bring out the most in my room!! Is there really that much difference between them?

Also which Axiom setup would best suit my room size??

Thanks in advance
