Re: certain subs getting "lower??"
Some somes have a lower fs which is the same as a slope on an amp. Its the point where they are going to start dropping off. They will still play the entire freq range bit may be stronger lower then others. Like DD and DC. Two totally different subs for different purposes. Both can play low, both can get loud. One just does low better, one does loud better.
