There was a Stax interview few years ago, in a japanese magazine.
(since english is not my mother language, I translate it as good as I can):
Most parts of the drivers are handmade.
1.Preparation: First, the diaphragm & dust cover, Attach the mylar diaphragm to the metal frame,
The diaphragm must be totally flat,no folds,the method is secret.
Then the dust cover, use fingers to rub it, slowly,This will add folds on it, to avoid frequency resonance, it takes 30 hours.
Every metal frame is washed & cleaned carefully, to remove small metal wires. the painting of the stators is a time consuming work too.
These preparations takes a lot of time
2.Assembly: The electrostatic drivers are assembled in a clean room,
there has a dedicated vacuum cleaner, The workers are wearing white clothes.
Under a magnifier, they use tapes to remove any dust on the parts .then assemble them.
3.Inspection: They use a 40years old, handmade measuring instrument to do this.
Measure the sensitivity, tension etc of each driver,and some noise tests,
then matching them. after these, the drivers are put in a box with hygroscopic agent.delivered to the headphone assembly factory.
Because the diaphragm will stretch when temperature changes, the storage temperature is controlled at 20'C....
