Fully agreed with Cat. I would have gone with wall mount of full size M22's if i could have. The in/on wall was the best compromise I could make.

I have not heard the EP175, but I would agree an EP350 should be the minimum from Axiom for a movie setup. Keep in mind that the EP350 and 500 share the same cabinet, so if budget is not too tight you can upgrade to the 500 for the same footprint as 350.
