RP again welcome, The Aperion/Axiom mix works well for me, I think the downside of non-brand matching speakers is the tonal quality may be different. I haven't noticed on my mix and love the sound , but I'm not as experienced as many on this board. The Aperions are great speakers and I have no regrets, but if I was to do it over I probably would have gone all Axiom. Also I think once you hear the EP500, you'll make it fit, that sub is incredible.

A computer once beat me at chess, but it was no match for me at kick boxing.
