Cjucoder, we often recommend purchasing only a center, or a front pair, to see if the Axiom sound is for you. It's a wise thing to do. Axiom maintains a return center in Buffalo. So, should you decide to return the speaker, it's not like you have to return it to Canada, and the return postage should be minimal.
It wouldn't hurt to give Axiom a call, and explain your situation and your concerns. They are very helpful, and will not try to talk you into something you neither need nor want. They'd rather have a satisfied customer than a quick sale.
Newbies are always welcome here. The only people who have trouble here are the rude and inconsiderate.
