Crossovers and test with scope

[carlthess40]

Hello
I have a few crossovers and and I meters for testing ESR and many other things. And I have a scope
Here’s my question
How can I use my scope to find the crossovers points of crossover for say a 2 or 3 way, I’d like to find where the woofer, mids and tweeters are crossed over at
I also have a diy electronic crossover. It’s prime build was as a 3 way, the former owner did some tweaking to make it a 2 way
I can’t find any info on it. It was made for
A boom buy and so on. Here’s a few pics of it
Thanks guys for any and all help

Multi channel 'scope? If so monitor the outputs and set signal generator to the point the outputs are equal amplitude.

Single channel 'scope will take a bit of switching back and forth with the probe to find the equal-amplitude point.

If there's any variable gain section you'll need to temporarily set that to unity gain.

Perhaps using a soundcard and e.g. REW or ARTA transfer-function measurement instead of a scope?

Both good ideas. I have a two channel scope and do have a few good sound cards
I have REW but have not spent any time with it. So I have a large learning curve do tackle
