If you're referring to foil inductors, then they do not have polarity. You can hook up either way it should be fine.
In a speaker crossover, are film inductors directional or have polarity?
Tried asking this in the speaker forum, no responce. Thought I'd try my question here......In a crossover are film inductors directional? Are there general principals to what should connect to inner foil vs outer in regards to the flow of electrons? Would it matter if both speakers were connected in reverse to each other, ie inner foil to outer and outer foil to inner??
