Built a 2x12

It's a cab. Made of 18mm ply, spec'd out to use half a sheet (1200x1200).
The back is 1/3 convertible because I couldn't decide on open or closed back so went with both options. This is made with dowel construction, not screws. No real reason, I just prefer dowels.
The red interior is empirically proven to increase chugs by 10%.
It's got 2 of these speakers in there from 1986 wired to 8 ohms at the jack:
Speaking of the jack: normally I use those metal plates and then attach a jack to the plate. For this one I just used a locking Neutrik jack that needs a single 25mm hole:
It's much simpler combining those 2 parts into a single thing that does a better job in a smaller form factor.
I built this with a jigsaw for the cuts, a power drill for the holes, orbital sander, and a rasp I used for the DIY roundovers. You can hopefully make out there's a little bit of an angle to the front too which aims the sound a little higher than usual. And we all know every cab needs locking castors.
There's grille cloth coming in the mail but the cab is complete for all intents and purposes... maybe some handles, maybe some leather corner protectors in the future but it works, sounds great and does exactly what I intended. There's a lot of low end lurking in this thing with the back enclosed, and a fantastic snarl with the back opened up.
Here's the plans I drew up. You'll need to tailor the baffle and back dimensions to your method of doing things.
Butt joint the pieces, reinforce the corners internally with 19x19mm strips, caulk everything to make it airtight, secure the baffle and back to the internal frame and you more or less have a cab.
