require is a very strong term.... I've yet to see a driver that sounds like absolute poo unless in a ported box.

Yes, the QTC, Vas, and Fs do have a great effect on if the sub is best suited for ported or sealed, but with virtually any sub on the car audio market you can get decent results with either.

a QTC of .4 or lower means ported would be great
A QTC of .4-.6 means Sealed would be best
and anything above .6 means IB would be best... but IB really is the same as a giant sealed box.

most car audio subs have QTC's in the range of .4-.55 as the best way for stereo companies to make money is to make it work in BOTH types of boxes and have a broader market sector.
