Mojo , the EP800 is essentially 2 subwoofers already so yeah i can see how you wouldnt really require 2 of them together. I have a pair of 10'a on a concrete foundation that shake the walls and move the couch. A pair of 12's in my car makes the windows flex.

Really your room is 10,000 cubic feet. why so big

DOG is GOD spelled backwards.
