What is your budget? Have you looked at the Axiom factory outlet to save 10%? Normally you want to stay with the same brand so the speakers are voice/timber matched.

The q's are the best surrounds around, so you would be better moving the Ax2's to the rear channel, and get Qs4's or Qs8's for the side surrounds.

I would think the current Vp100 or VP150 would match up with the AX5's.
