vmrao,
I'm not qualified to give you the type of detailed info you may be seeking on the JMlab Chorus 706. What I can tell you is what I thought of them. They sounded great; the midrange and treble were identicle, to my ears, but they were a little weak as far as bass goes. BUT, the Axiom has 2 bass drivers, and the 706 has only 1. So, the Axiom had a better 'full-range sound'; I like a healthy amount of bass, not too much, and if my subwoofer was broke, I could live with the bass supplied by the M22.
I chose the Axioms because of this, and they were $50 cheaper,AND you have 30 days to try them out!
Thats pretty much all I can say; I'm sure you will be pleased with the JMlabs, and the Axioms. In the end your ears will decide which is best for you.
Good luck.
