What makes speaker's sound big?


Does a speaker need to have many drivers or a large driver area to sound big and fill the room?
I am asking this question because I have a pair of tekton design double impact and would like to replace them with smaller speakers and a pair of subwoofer's to better integrate the bass into my room.
I just borrowed a set of B&W 702S. The are good but the just don't make that floor to ceiling sound that I like.
Maybe I have already answered my own question (: But again I have not heard all the speakers out there.
My room measure 15x19' and the ceiling goes from 7.5 to 12.8'

Mikelavigne, where you said....

some good mid bass is also helpful; again the speaker driver surface in the mid bass needs to be matched to the volume of the room so it can propagate. the whole room needs to be energized.

is there a formula  one could follow in order to size the speaker system to the room?
