Beyma 12B100DB musings

Hello all,
a bit of a newbie here, I would like to exhume from the garage my 12" Beyma 12b100 DB (DB for double bobbin) and would use it with a 45 (net) liter sealed box I have ready to get me going fast, using it as the main subwoofer with my Pawel monitors for 2.1 listening.
I am having already a Behringer dcx2496 to process the preamp analog output and one channel 130W/8ohm class AB amp.

Is anyone having the specifications of this driver maybe? I seem to find the 12b100 specs quite easily but the double bobbin does not seem to be available.

I might try to apply/learn Arta/Limp/Hornresp in the process later on to simulate/optimize the Beyma..

Cheers and beers!
