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

As a general rule of thumb, speaker x-overs don't have polarity. Are we speaking about active or passive x-over?

I think you mean film capacitors.  While they usually aren't directional, often it is seen as better to hook one end to positive.  they are usually marked by a long lead or a mark established by the OEM.

     As mentioned: you must be referring to film capacitors, as there are no film inductors.

     There are FOIL inductors, to which you may be referring.     Their orientation makes no difference, far as noise or inductance value.

Thank you all... I was refering to foil Inductors, my mistake.
