What's this crossover?

Just when I thought I might start to understand, I pulled this bundle of wires out of a 27year old set of ALBA speakers. Can anyone figure out what is going on here?

They sound ok but lacking in top perhaps. the "tweeter" is a 2" paper cone!

BTW sorry about the symbols. Standard AutoCAD. Does anyone know where to get a set of SI symbols?

I think I get it . The components are being used by both drivers at once. The tweeter becomes a coil for the woofer's circuit

So I get a 2nd order butterworth hi pass, and a band pass. Like these.

Is it ok to do that? Can an inductor work properly with 2 jobs?

Using the calculator and the 20uF value for the cap I guess the crossover frequency is 700Hz. Am I thinking correctly?

If I swapped the paper tweeter for a nicer 8ohm dome. Would the change of inductance make a big change?

No

It's somewhat of a series crossover, but since the resistor in series with the tweeter is so large a value, the tweeter does not output anything. Could the cap have been in parallel with the resistor instead?

Caught you again. Twice in one day. Excellent.

Why isn't it a series XO bill... sure looks like it to me.

Because the tweeter isn't functioning.
