"THX reference level for a Dolby Digital movie's LFE is 115dB, so if you consider that each additional driver, receiving the same signal increases total SPL by 3dB, it would take just over 11 additional drivers based on your 80dB figure. Your calculations are a little off base."

Um not exactly. For every doubling of driver quantity you get an increase of 6db. 3db for each doubling of voume displacement, and 3 db for each doubling of power. So:

2= +6db for 86 db
4= +6db for 92 db
8= + 6db for 98 db
16= +6db for 104db
32= +6db for 110db and a final
64 = +6db for 116db

look it up in the speaker building Bible, Vance Dickasons Loudspeaker Design Cookbook or any number of other speaker design or acoustics books.
