Anyways, my question is, for subwoofer duties with frequencies less than 100hz, does a VERY VERY stiff cone ALWAYS have an advantage over a less stiff one? Also, what about cone weight? Will a lighter cone always sound "more accurate" than a heavier one?

And, if you increase cone weight, you decrease SPL, decrease the FS, increase the VAS, and Increase the QMS right?

Thanks!
