    So I've got two fEARful 15/6/1's in progress, and I've run into an electronics/wiring issue. I got pre-made true crossover boards from SpeakerHardware, and I've got them mounted and totally wired up. If I plug-in to my power amp, the sub and tweeter are working ... but no mids!

    If I hold my soldering iron close to any of the inductors on the mid crossover board the mid speaker emits some static sounds, but that's all I can get.

    Does anybody have any troubleshooting tips?

  2. I wonder if you hooked up the mids to the tweeter outputs.

    UPDATE: For whatever reason, reversing the polarity on the Mid connection made everything work!

    All done now :)

  4. I would imagine that resoldering had more to do with it than reversing it.
    Glad it worked.
    Great looking cabs!

    Gorgeous cabs! I'm working up a pair myself, and curious about the wiring. Do you have a schematic you worked from? I suppose it's pretty straight forward, but I'm anxious to not mess up.

    Oh, I should mention: I'm omitting the tweeter, just woofer and mids, got the CBG crossover from Speaker Hardware.

    That would help with putting together the actual boards, if you need that.

    For help wiring them together, someone else here may have the diagram(s) on hand - I don’t know where the ones I used ended up.

    Leland at Speaker Hardware could help, too, I’d imagine. He was helpful to me when I was making mine. There’s a Greenboy thread on TB with plenty of knowledgeable folks, too.

    Thanks! I think I found what I need, but I just tend to be (overly) cautious.
