It's clear that hondasnl knows more than scott+Dave+GM+the rest of the forum.
So why do you ask?

This seller also has own measurements and warning that the GRS TS spec can and will not be reached for this driver

I don't know what happened, but the answer, I think, was in English. Sorry.English please

i like fullrange drivers like the grs 8 inch and strive to bring oneway principle to its best results. Because a speaker without faults in the time domain has its sonical advantages

IIRC this website either once had an English option or Google could translate it, but there's apparently neither now, or have I missed something?
Regardless, these are 'best' specs so far, but 0.7 Qts still technically well beyond the most extreme EBS alignments:
Thiele-Small Parameter(aus eigener Messung)
Nennimpedanz/Gleichstromwiderstand: 8 / 6,8 Ohm
Resonanzfrequenz: 65,9 Hz
Gütefaktoren(Qms/Qes/Qts): 6,36 / 0,78 / 0,70
Äquivalenzvolumen(Vas): 18,7 Liter
Effektive Membranfläche(Sd): 214 cm²
Antriebsfaktor(BL): 6 Tm
Schwingspulenimpedanz (Le): 0,71 mH

You have to click "Produkte" (for products). then "Breitbandlautsprecher" means fullrange drivers. Then you get big list overview of fullrange drivers and you can click every driver for more info
Those parameters are probably closer to the truth.
Yes there was an English one before.
Especially the inductance 0.71mh still OK for a fullrange. But anything more than 1mh is more for woofers
As long as you could get this was my favorite allround fullrange
