After a few design iterations, I had a working design for a shell that securely holds the #USB2Speakon PCB in the back of the plug.
But I had to relocate the bodged on crystal to the other PCB side, so it would fit inside.
The shell fits snugly and keeps everything together even without the outer housing screwed on.I also bodged on a 470uF capacitor as a tiny energy buffer, I think it helped a bit with clipping, but obv. not too much.
And with that the first prototype was done™

Step 5: Notice that LCSC sent you the wrong crystal. (See 1st picture, they sent 16MHz instead of the ordered 6MHz)
Step 6: Bodge on a THT 6MHz crystal, acquired at a local electronics parts store.
Step 7: ???
Step 8: Test the now working #USB2Speakon PCB -

*insert standard run-of-the-mill #PCB assembly steps here*
Paste, place, reflow the one side.
Solder the other side by hand (because I didn't have a hot-air station at home and was impatient). -

Here is a demo video showing the #USB2Speakon in use.
I'm not sure if the camera microphone captures it accurately, but it's _surprisingly_ loud :D
(I expected around "room volume" at most)Build log thread coming soon™

Latest project in the category "Is it actually useful or just an elaborate #shitpost?": #USB2Speakon!
It's a fully self-contained, USB-C-powered, 2-channel DAC + 5W Class-D amplifier inside a #Speakon connector.
Use it to connect your phone / laptop to any passive loudspeaker and enjoy surprisingly loud music (probably enough to host a room party)
(GitHub link for the interested: https://github.com/RainbowLabsDE/USB2Speakon )
Video of it in action and build log below:
