[QUOTE="Goldtaz1, post: 1063849, member: 555012"] If the x-max parameters of a given 12 and 15 were exactly equal then based on sheer Sd (cone area) here's what you'd have: typical 12" driver Sd = 420 cm^2 typical 15" driver Sd = 810 cm^2 So (4) X 420 = 1680 cm^2 and (2) X 810 = 1620cm^2 Really and truly this situation is a toss up because the 15's will be potent because of sheer cone area and excursion, whereas the 12's would be equally as loud because of sheer quantity. Personally I am a 15" subwoofer kind of guy (most recently I have become an 18" guy). You will probably be able to have a much smaller box with the 15's whereas the 12's are gonna need a bit bigger box. I guess it really depends on what you have the room to do? [/QUOTE]
