One quick point re: the sub choice...FWIW, don't forget that an Axiom sub will match the finish of the new speakers (unless, of course, you're looking at black for the Axioms anyway in which case it probably doesn't matter).

It's a small point for many, but it was important to me since my sub was going to be in a visible location, and I know it's sometimes important to others who need a good WAF (Wife Approval Factor) for harmony after the sale!
