1) Yes we still OEM drivers for a very few manufacturers but they are 2-3 generations old drivers NEVER current technology. Merlin uses the old Esotar tweeter as does Eggleston who also uses the old 12" woofer(30W100). Totem uses our drivers in only two models, the Model One and the Mani 2. Duntech used our drivers in many applications and we still supply replacement drivers to Duntech owners. Wilson used our drivers back in the early 90's, Rockport used the Esotar tweeter, Sonus Faber used the Esotar tweeter in the Extrema, etc, etc.
Hope that helps a little
BTW the Dyn C1 and discontinued special 25's use the esotar2 tweeter
