I rebuilt and altered the crossover circuit on the worse of the two speakers. Check it, here’s the new crossover. I kept the original coils, but moved them so they’re out of plane with each other, which matters for clarity and prevention of crosstalk.

New Crossover
I made a phone recording, just using the built-in microphone. The last recording, of the other speaker, I was able to get it sounding reasonable through inappropriate use of EQ once I got the tweeter to come back online. Even that was a huge step up from where it had been.
This recording? Purely flat equalisation. Absolutely flat. Played off an iPod through my Sampson amp, into the speaker, recorded via phone mic.
This post is part of a series on restoring infamous vintage stage monitors. Spoiler: they made good, in the end.

So, I still lean that was a from that school….and was a student project. I am happy you are having fun with this.
Maybe, but the crossovers were both bought retail from a shop in Portland for $33, some time ago. The only part left as a “student kit” at that point would be the case.
