Perhaps he could order the towers first, to see if he likes the Axiom sound vs a whole HT. Then after auditioning at home for a few weeks he could go ahead and order the rest of the system(I believe the HT discount still applies within 30 days but check with the folks at Axiom) or if for some reason decides they're not for him, he only has to return one pair of speakers(M80s vs whole HT). The downside of course, is not hearing the entire HT when the cannons start firing!

Half of communication is listening. You can't listen with your mouth.
