What is this? (speaker circuit) Answered

I found a pair of broken speakers in a junkyard a while ago and wanted to take the good-looking connectors. When I removed them from the chassi I saw that there was a circuit board on the other side and now I wonder what it does. At first I thought it was an amplifier, but there is no connection for power or batteries. I made some schematics of the circuit, I hope that will help. Gogo gadget, internet community intelligence!

Looks like a passive crossover circuit. No batteries or power == passive.

It's an audio filter for speakers. I.E., it feeds low frequencies to the woofer, and high freq to the tweeter.

"L" is the symbol for inductor.
