AxiomJackson,

I can chime in here on the dual EP500's. I spent a year trying to get that "satisfied" low end rumble, depth and punch with 2 different subs.

After getting the dual EP500's I couldn't be happier. I currently have them stacked one on top of another and it's just incredible.

If you go with 2 EP500's, you won't regret it.
