It's interesting to note that even loudspeaker manufacturers can't get every driver of a certain model to sound and measure exactly alike. Small differences in things like suspension and cone thickness cumulate to make variations in T/S parameters like fs and Qts. I've read of some people who measure fs of a given driver to be off as much as +/- 10 dB. It's just very hard to get a vibrating surface to perform exactly like another. That's why it's usually recommended to measure each driver individually before designing a given enclosure.
