Axiom Home Page Forums General Discussion Advice from Axiom Owners What's Wrong with Axiom Subs?

OK, experts, here's an axiom sub question for you:
Background: I have an empty 14'x19' media room just waiting for me to fill it up. I have appt's to let local Home Theater (Tweeter and HomeTheaterStore) guys look at the space and make recommendations, but I have doubts that I will give them my money.
So, I'm seriously considering Axioms and every time a walk through the Axoim 'wizard' it ends up recommending TWO subs. Can anyone tell me if and why 2 EP175's would be better than 1 EP350?

Thanks,
Wyatt
