Thanks for the replies, everyone. I think I'll try listening to the Axioms on their own for a while. If they sound good enough, and if I don't miss the deep bass too much, then maybe I'll try to find someone who can take these subs off my hands. It's hard to go back to regular speakers once you get used to that deep bass, though. And to think, just a year ago I was listening to a small little Aiwa shelf system with not a care in the world. Ah, memories.
