Well…. That was anti-climactic! Lol
Finally hooked everything up with clip leads to the -3db setting on the autoformers to start.
No output from the horns, very quiet output from the woofers…. Time to go back and retrace my wiring diagram against the schematic. Must have made a mistake somewhere…
Maybe tomorrow. My eyes are tired after staring at screens all day.
Man, that….damn….close!

If anyone wants to look over my wiring diagram I would GREATLY appreciate it. Perhaps some fresh eyes are what is called for here.
I didn't check everything but, it looks like you are missing a connection on the high frequency side. The junction between the 19 uF cap and the 3.3 mHy coil needs to connect to the 12 ohm resistor. Which on your layout would be the right side of the resistor. Maybe other issues on the HF filter, but look there first.
Thanks for both of those suggestions. I’ll have to print these out and take a good long look at them again with your suggestions.
My first thought was look at the autoformers, being it is both low and high frequencies.
I went back and retraced the circuit again and compared to the diagram. Your two suggestions were exactly where the issues were. Thank you so much for taking the time to look it over. Not sure how I got my wires crossed (pun intended) there. 😉
Used some clip leads to make the correct connections for 3db attenuation and voila, we have 🎶
Let’s see if it lets me post a video. Kids are watching the new Selena series on Netflix, so they chose the first test song.
Before I forget...and for posterity's sake, here is the corrected crossover layout:
Also, I replaced the incorrect one earlier in the thread to avoid confusion with a note.

Have you passed this by Pete to see what he thinks?
You know, I don’t know Pete at all.
I know you met him a while back. If you want to run this past him I would be very appreciative of his feedback.
Think he’s referring to Pete Riggle.He said for posterity sake not Petes sake.….Carry on gent’s.
Any listening thoughts or updates on this build you care to share with the group?
I'm thinking about something somewhat similar 15"+ large format Cetec Gauss HF-4000 compression drivers.
Love to hear your thoughts on the crossover/notch filter/autoformee as well.
Hope you're enjoying them!
