I'm happy with just one sub (at least at the moment) which is sited to the right of room. Even though I'm using a 80Hz cut-off, the sub doesn't betray it's location. Personally, I would go for one decent sub that can move a significant amount of air below 30Hz rather than two smaller units.

Edit: above implied for movie use (and you could lower the cut-off with your speakers)
