Sadly, I don't think the EP175 would satisfy you.
If you don't mind me barging in, I wonder if you wouldn't recommend the EP175 just in this case, or wouldn't recommend it, period? I've been the satisfied owner of two M22's for a couple of years and now I'm thinking of moving into a 5.1 all-Axiom system with the EP175 as a sub.
I'm not looking to dance around with the coffee table, so to speak, but I want a sub that will complement the M22's on the lower end. We don't have a huge living room (11,5 by 18 feet) and music is much more important to me than movies. What do you guys think? Will the EP175 work for me? Should I look into other options?
