In a speaker crossover, are film inductors directional or have polarity?


In a crossover are foil 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??

No, inductors are not polar components. Inductors are passive two-terminal components that store energy in a magnetic field when electric current flows through them. They do not have a specific positive or negative terminal, which means they can be connected in either direction in a circuit without any impact on their performance.

In contrast, some components, like electrolytic capacitors and diodes, are polar, meaning they have a specific positive (anode) and negative (cathode) terminal and must be connected in the correct orientation in a circuit to function properly.
