can anyone explain?

i know that bigger does not mean louder, but what i dont know, is why larger subs (ie ones with more cone area) can hit lower freq's than smaller subs...can anyone explain this to me?

thanks

this may not be right, but the way i figure it is in order to get a lower tone, the sub needs to move more air, and a bigger sub has a bigger surface area to move more air. like i said, that may not be the right answer, but i think it is. also, kinda like how a tweeter can't play low notes because it can't move that much air.

well- i dont think the fact that it can move more air has anything to do with the frequency (how many times the cone completes a cycle). If you put a 25hz sine wave into a 10" sub, i am under the impression that it would not be as audible as the sound comeing from a 15" sub putting out a 25hz sine wave...im pretty sure the reason for a tweeter being small is because if it were big, you would need an EXTREMLEY lightweight, stiff cone that is capable of being forced in and out 15,000 times a second...this would mean you would have to have a ridiculously strong motor structure and lightweight cone...
