T-B W3-2141 measuring way off spec - anyone else used this driver?

Updated original post with T/S parameters as well. Fs seems to have gone up since I last measured, but gave them more break-in. Impedance went down, but possibly due to more careful attention to calibration; I went through the whole process fresh this time. Re is still quite a bit higher than spec, as is Fs.

Just noticed these drivers were used here: https://www.youtube.com/watch?v=kAoqVH1w3uc
Although a detailed response isn't posted you can see at about the 6:30 mark when measurements are taken they end up very similar to the ones shown above in Post #14.
Same 1-2K hump, drop off and then twin peaks up over 10K. They don't show the same sharp increase around 3K though.
In any case a fairly challenging little driver to get a smooth response from.

If an established manufacturer like TB is making drivers that are mostly going to be used in hardcore applications with serious users, with measuring equipment -- those who end up posting threads like this -- why would continue they publish specs that are so far off?
Surely the black marks would add up, no?
