Customer Questions

Thank you for your supply, but how do I identify which side is positive + and which is negative - ??. There is no marking for either, however one side has a recess the other no recess. Thank you. Question posted by Alexander

Theoretically the same as the polarity than the original one depending on the position of the ergo (uncentered and asymetric hole on the support of the diaphragm).
