I’m finally in the long home stretch completion of my 2 Jack 12 Lites with Leland Crooks excellent build of 2 full piezo arrays.
Looking at the build out for the crossover, I am looking for any pics you might have of your examples. I know there are some crafty things you have done.
Also, I’ve seen some ideas of using hot glue for the components, but I don’t feel they will be sturdy enough over time. I was heading toward cable ties.
Thank you in advance for your comments. This forum is a big help to all.

Re: Jack 12 Full Piezo Crossover Pics
I used terminal blocks when I built mine for my j-arrays, assuming jack x-overs would be similar. Was real happy with how they turned out and minimizes the soldering. I have a pic in my build thread - not sure the hyperlink is pasting in correctly - but you can search for it under Otop Jarray build. I used zip ties and hot glue, and I think maybe even some PL for extra hold.

Very nice and clean!
I'd like to do both filters together and mount them on the back cover on one side with the 2 combo jacks on the other side.

I used turret board construction since I build tube amps once in a while. These are from my Jack 10's.
Definitely wire ties for the heavy items.
