Anyone know what these are


I picked these up at an estate sale recently, and am wondering if anyone can explain their purpose. They weren’t hooked up when I bought them, but the estate included a high-end Linn / Legacy / Conrad Johnson system, so I thought they might be interesting.

Circuit looks like a capacitor, a few resistors, and a wound spool of wire, all on a basic switch. There are two of them. Guessing maybe some sort of filter that goes between an amp and speakers? Thanks.

Does the other one (not pictured) have a red or black binding post? Are they identical inside?
I don't see any capacitors involved. Since there is only one in and one out, it's safe to say the entire circuit is in series. Nothing shunts to ground. Therefore the circiut is something like this:

0---vvv-vvv-vvv----uuuu---->

with "vvv" representing a resistor and "uuu" representing a coil.  "0" and ">" representing the input and outputs.

Somewhere around there the switch bypasses some or all of it.

Clearly someone was playing with a bass cabinet somehow.

Best,

I see at least one cap, barely seen at the top of the picture behind the 10 ohm resistor. There may be more behind the other 10 ohm resistors.

Are those 10 watt resistors?

 Yes there are electrolytic caps. Low pass passive crossover in my estimation.
