Does anyone have the schematic for the said crossover.

A friend has only one box and one coil is burned so no way to know what value it was.

Would it not be possible to measure the diameter of the wire, then unwind the coil and count the number of winds?

Looks like replacement crossovers are available.

EDIT is this a ev-elx12 or ev-elx112!

There are 2 inductors on the 112 PCB one air core & one with a laminated core.

It might be possible to figure out the value of the air core - there are online calculators that would help, but the laminated core inductor value would be dependent on the core as part of the overall inductance.

At a pinch it might be possible to unwind the coil and rewind one but just might be easier to buy a replacement!

Ordering replacement crossover is not an option. Shipping and customs fee will get to like half the value of the entire box.

The laminated core inductor is completely melted and not possible to unwind without breaking the wire on many pieces. The rest of the crossover is fine.

Otherwise i would just unwind, mesure the wire lenght and just rewind with a new wire.
