Qts? Vas? Fs? Xmax?

These measure different than specs. but are consistent with each other.
FS 82 Hz, Qts. .559, Vas. 2.4 Ltrs. Le. 1.191 mH.
Qms. 4.146, Qes .646. Xmax from doing math off of the spec. sheet would be 5.45 mm one way.

New or used? I have A pair of NS-4's laying around , but I'm not sure theyre the same ones , if they are I may be interested , with four I could make some small Mtm's.
