Here is my first DIY sub! The bracing on the inside is a bit over-engineered, but it should at least be well braced and I think it looks cool. I was going for the window-pane style bracing, but required some of the portions to be circular to fit the subwoofer. I also added extra bracing to make sure no portions of the outer panels had too much surface area without bracing, in case there were any resonance issues. I designed the box in Solidworks and then had the pieces CNC'd. Unfortunately I goofed the tolerancing a bit, so some of the datums and grooves required a bit of sanding to fit. It uses a ton of wood glue and I sealed the inside seams with epoxy.
The subwoofer used is a SI HST-18 MKIII. It's a beast of a sub! The weight of the box was ~80 lbs and the sub is another ~80, giving a total weight for whole thing at 160+ lbs. The dimensions of the box itself are 22" x 22" x 22" and there is a neutrik connector in the back.
I'm calling it "The Tesseract" because it's a complicated cube structure that is blue (and I love the Marvel movies). Hope you enjoy seeing it!

Would it be possible to use plexiglass on a few panels? Throw a few blue LEDs in there for effect

You can always turn it down, but you can only turn it up so much (before you run out of power, excursion or structural integrity).

I was thinking some printed "veneer" to look like the tesseract would be the easy way. like a vinyl wrap. Ive actually seen a way with epoxy counter tops with fiberoptic lights embeded that had a really cool effect.
