If your room is large, go fo two subs - I have tried one and two subs and found a lot of differences, particulary on how two subs clean the midrange better than on trying to cope with both channel information.
I might be a different animal, but the radiation pattern is localizable from my listening position (my room is not huge as you mentioned is yours) thou.
Good Luck
