what is it and how does it connect?

Found this in an old box of parts and vaguely remember it coming out of an unpowered subwoofer. Can anyone explain how to render it usable again? Thanks!

I suspect it is a low pass filter cross over for the subwoofer.

And a high pass for the satellites? All first order?

Or 2nd order on the woofer and straight through for the satellites?

Or straight through to the woofer and 2nd order to the satellites?

Where are the leads that go to the woofer?

passive subwoofer crossover. leads for the woofer(s) are the ones on the crossover as it should be mounted in the sub box. most ive seen are typically 2nd order low and high usually around 125hz and rated for 8ohms per channel. again, in most ive seen, it was typically a dvc woofer then out to satellites. vega had a stealth series, rca had a popular htib for years utilizing them. fun way to make a passive 3 way with off the shelf parts...just pair with your favorite bookshelf speaker and go.

Snappyturtle...so the red, orange, blue and black leads go to two (?) speakers in one box, then the speaker out leads from the amp goes to L & R in, with L & R out remaining empty? Sorry to be so dense but I'm a complete novice at this sort of thing!

amp L+R out to xover in. red,orange, blue and black go to 2 woofers in same box or to a single DVC driver. Speaker L+R out to satellites.
If you want stereo woofers under the satellites, keep crossover as a separate near the amp and just run speaker cable

The subwoofer must be of the (acoustic) bandpass type and the satellites sealed to have a full crossover. A 4th order bandpass subwoofer is common with such crossovers.
