I would go for the Outlaw, Hsu, or Rythmik. I don't think the Epik would be substantially better at deep bass then the Emotiva. By the way, I don't think just one of any of these subs will give you monster output in your room, especially if you are seated in the center. If your budget is tight, two Emotivas might be your best bet for any kind of decent bass at all, unless you can place the sub nearby, like an endtable, in which case I would go for the Hsu or Outlaw.
