Welcome Max, I agree with John, use the QS8's as the side surrounds and the QS4's as rears.

So far as the delay, did you order from the Factory Outlet? If so that would account for the longer delay, if not I would suspect that Axiom had a run of your finish choice and this made for the delay. Axiom usually never ships air, so expect at least 2-3 days if not more, as I am sure your speakers will be held up at the border.\:\(
