Berny is right. It really depends what you are used to listening to. If you grew up listening to direct radiating speakers like most people on the planet, Axiom may sound bettter to you. If you are one of the rare few exposed to horn loaded speakers as a youngster, JBL is a very well established and respected speaker mfg that has been around a long time.
You should be able to audition the JBL's readily as dealers are almost everywhere. Not so for Axiom so listening to both may be a problem before purchasing.
