I really can't help you. I have never heard any of the home speakers produced by JBL. If they're anything like the JBL Pro LSR speakers though, I'm surprised you don't consider them musical.
I do rather like my EMP e55tis however. For about $600/pr one couldn't ask for too much more.
Another speaker you might consider, if high output or a wide sweet spot aren't necessary, would be a Magnepan MMG.
