MDF is used for its high density (I know, M stands for medium) and low resonance factor.
SB, I personally like 12's better than 15's. I think you should have gone with 12's. They perform better in the upper range of frequencies and the lower range that the 15's go down to can't be heard anyway. You get a tighter bass. 15's always seemed sloppier to me.
Agreed. 1 15 or 2 12's. Resonance in the car is going to be fucked. Anyways.
