Jay, I especially agree with Mark and Randy that you can't have it both ways; very deep and strong bass might disturb neighbors regardless of whether it's coming from a sub or main speakers. Although this would lose the advantage of corner placement that separate subs make possible, some do use a sub immediately alongside(or for concealment, immediately behind)each main speaker, forming almost a single unit.
Another point which would seem a bit curious is using a 2.0 setup, regardless of how strong the bass would be, for movies. The surround effects furnished by at least two surround speakers are of major significance.
