Hi Jrain and welcome. My guess is that the wizard is choosing the EP175 based on your music choices and room size..(small to medium?)

Why is the EP350 not designated the EP200? Dunno! What's in a name anyway? If other Axiom owners don't know, I'm sure the Axiom staff would gladly enlighten you, if you're curious enuf!

Besides the 25 watt amp differential, the EP350 has a larger cabinet and driver (12" as opposed to 10"). It will go a bit deeper than the EP175.
