For your musical tastes the Axioms would likely be a good choice but I question whether you need that many speakers in a room that size. If you go with Axioms a single pair of QS8s (located properly) would give you a pretty encompassing sound field.
I did audition some JBL E30s vs. Axiom M3s vs. Monitor Audio Bronze 2s. The JBLs had VERY bloated bass and a sssssssssizzzzzzling tweeter, but you would be using them as surrounds so maybe that wouldn't matter. The Axioms and MAs would both be better choices from the listening I have done. MA also has dipole surrounds, right?
