Hi AJ and welcome. I don't have experience with your JBL's, but even if you don't get enough of a response from folks regarding your speakers, I would still suggest you consider auditioning the Axiom speakers of your choice, so you can compare them in your environment. I was in the same situation, only with Infinity Kappa 8's. I took a leap of faith ... and never looked back.
No matter how much feedback you may get here, nothing will compare to having the speakers if front of you and listening so YOU can decide.
PS... I'll be looking to sell the Infinity Kappas soon if anyone's interested!
(PM me of course)
