An electrostatic speaker works by sandwiching an extremely thin, conductive diaphragm that can move between two perforated, stationary metal panels. The metal panels are called stators.
MartinLogan has the stator panels made by an outside vendor, but the panels are then finished in-house. The first step taken with the raw stator panels is to run them through a machine to deburr them -- in other words, to get all the rough spots off.
The stators are then hooked onto an elaborate pulley system that first pulls them through a washer and then . . .
. . . through another machine that powder coats them.
The final step in the stator-preparation process is drying.
