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.

hard to say w/o tracing it out but that is a good sized inductor in there

sell it to a copper recycler
Without being able to see all of it, it looks like a speaker level low pass filter, with a  bypass switch.

I can't tell if there are also resistors or caps involved. However, if it's just an inductor in series, that's what it is.

Best,
