I've been assembling some Theater Series four π Speakers, and I took a moment to get a photograph of bracing. The plans all say "install bracing every 18 inches" and I commonly tell people to preload long panels by installing 1" x 2" braces between opposing sides. So here's a couple of photos that show them installed.

Moved in closer, showing two between the sides, and two from front to back
That's super boring stuff.
But I've got some very exciting information that I'm just dying to share. It's really Bill's news to tell, so I'll leave it to him. I'll give you a hint: I've got something right here that's really attractive, really cool, and really sounds good.
OK, Bill, that's your cue...
