Hi Mark,
I really respect your position to pay some heed to the aesthetics of the situation.
I'm totally speculating here, because I don't own either model, but I'll give you my opinion for free. One time only. Call before midnight tonight. Not valid in all states.
The EP350 is 2 inches bigger in every dimension; it really is a bigger box and a bigger driver. It will produce lower frequencies and produce them more loudly. As to whether those differences are going to be meaningful to you in your room, only you can decide.
Didn't you have the very real prospect of moving your setup to a new, larger room in the future? If it was me, I'd future-proof the buying decision and get a Factory Outlet EP350 for $558 - the wait time is only a couple weeks.
You should call Axiom and talk to Alan or Joe or Brent or somebody about your dilemma. I'm sure they will be happy to advise you more capably than any of us numbskulls. On this topic, anyway
