Hi Steve. The simple answer would be to tell you they are terrific speakers. Rather than do that, let me suggest you spend some time wandering around in the forum and reading postings. Also, get on over to the Speakers section of AVS Forum and the Axiom forum at the SPOT.
At the end of the day, your ears will be the decision maker for you. The big kicker is to see if you can find some Axioms locally to audition and you can start that quest by looking
here . If no one looks to be close, drop Amie an email and see if she can find someone for you.
Whatever you decide, it will be right for you.
