Finished these up over the weekend. A few pics, some commentary about the build, then later I'll post some thoughts about sound quality.
Back corner to show the miters and veneer.
This is a little deceptive. Where's the miter joint?
Overall a relatively easy build. Any complexity was added to get a non-DIY finish. I think that was pretty much accomplished.
The red oak ply didn't take stain too well. After the 2nd coat, it wouldn't get any darker. It's not a match for my previous sub build, but I still like the tone.
Side note: never using masking tape again. The stuff just leaves too much residue. Next build gets blue painter's tape. Also, gonna switch to spray poly.
The miters worked out pretty well, and the boxes look good. Just need to get grills built, then these are done.
Thanks for the design, tuxedocivic! Thanks to Pete for the equipment, space, help, and expertise! And thanks to Erich for the components.
More about the sound later.
