After a really long time, I figured out what I wanted and built my sub into a TV/stereo stand with integrated center channel.
Because of where it goes, I didn't really have another option. Anyhow, the veneer lined port was a real trick to make (because of my screwup in making the hole for it), and getting so many joints glued at the same time was, too (slow epoxy if your friend). The sound isn't bad either. It passed WAF inspection. She likes my work.
