There was a posted spec sheet a couple of years ago, but the link is no longer valid. From the hard copy spec sheet I have, specs are:

Z = 4 ohm
Le = 0.6 mh
fs = 61.2
Qms = 2.85
Qes = .45
Qts = .39
Bl = 5.3
Sd = 141
Vas = 18.3
Sensitivity @ 2.83v/m = 93.0

The one material is an uncoated paper with inverted dustcap, and rubber surround. The frame is a natural color casting.

I was planning to use these in an MTM with a Vifa DX25, or maybe one of those Fountek ribbons.
