Dry fit of the baffle before sanding and finishing.
Final crossover design with baffle diffraction compensation on mid and tweeter.
Crossover design before baffle diffraction compensation, to show original results
FR accounting for baffle diffraction and with corrected crossover padding on mid and tweeter.
The actual size is 11-1/4" wide. Depth of the box is 14", ported to rear.
2330 in^3 (38.20 L), tuned at 37hz, using 3" round port 8.08" long.
Those built in grills are so pretty.
Gotta design some grill protection for these WOOFS.
2x12 Poplar from the mill, it was about $10 per linear foot. Green, but some oxalic acid bleach gets the sucker brownish/orange.
Jasper Jig is a gift from the heavens.

Tee-nuts to make sure I can take the speaker apart! These will also go onto the back panel in case I want to adjust the crossover after taking measurements.
After sanding to 180-grit and oxalic acid bleaching.
End goal for the baffle to be high-gloss natural finish, very light 'natural' stain color, but first gets oxalic acid bleached to take the green out of the poplar. The rest of the enclosure to be 3/4" MDF, satin black finish.
Still in progress build. Just finished the rough cuts and router work. I built speakers from a CJD design (Khanspires) years ago and wanted to make my own from scratch. Tried to watch a ton of youtube videos and tutorials and cooked up a crossover, so it might be trash, but I'll just adjust after measuring. First was going to build a simple 2-way with 6" and tweter, but I wanted more bass extension so grabbed the 8" with mid/tweeter. VituixCAD gave me a ton of help after first designing the crossover in Xsim, both in that crossover wizard thing they have for figuring out values and the baffle diffraction simulator. I got the curve from the baffle diffraction sim, threw it back into Xsim, then drew up the padding circuit for mid and tweeter.
Was able to get a lot of work done in the past few days after taking some vacation days off from work.
