Thanks for the feedback.
Spoiler, yes, I was choosing Med Sized for the Room, BUT the Wizard usually returns 2 or 3 configurations as possible options, and what I'd get back are setups with the EP500, EP600 and EP175 (tried a few times and chose different music and movie types), the EP350 seems to always be left out.

Of note, and to quote "The EP175 is "Joe's Pick" -- our Home theater Doctor's favourite subwoofer." I'm not sure who Joe is, but perhaps he designed the wizard?

Worfzara: Its good to hear this feedback. Although the room I'd be using this sub in is about 14x24x8, the HT-assigned area would fall in a 14x12 area of this room. I think it will suffice, and the size is appealing.

Has anyone started with the 175 and then moved to the 350, and/or compared these 2 subs?
