the 3 12's will be louder because of the increased cone area. the 2 15's will drop lower. Personally if you have the room I'd go with the 3 12's. BTW I've seen/heard lots of DD subs at the DB drag world finals and they are simply amazing. You aren't going to win any SQ competitions with them, but they will SLAM.
