   Since it's been so quiet ....  It has been mentioned that iron makes
a better material for sensor feedback coil transducers than steel. I
have two questions which maybe someone can help. Do manufactured speaker
coils have a better grade of material for use in feedback coils? I have
looked around a little but can't seem to find a source of  iron plate or
round stock. Any thoughts?
