that kind of peaking after bandpass lowpass cutoff can often be reduced or eliminated by changing/tuning the bandpass chamber and port

A notch filter would make pretty easy work of that peak. It's far out of pass band, so shouldn't be hard to do.

This next batch of pics will give you a glimpse into my sad home theater. Don't laugh, the whole reason I'm working on this project is to address this issue. I'm rockin' a very ritzy Ikea cabinet for my HT gear, topped with a piece of plywood because my new TV won't fit on it. (The old one did.)

The cherry on top is that my cat has destroyed my Vandersteens.

The dividers in the enclosure are cut on my K40 laser. The pieces are constructed the same way that Ikea furniture is, a CLD composite of cardboard skinned with plywood. The reason that the layers don't line up perfect is that I kept adjust the diameter until it fit perfect.

I once made a floor to ceiling cat pole, which was a cardboard tube from the center of a carpet roll, covered in carpeting, and it had a platform on the top that was the leftover from an 18" speaker hole cutout. Perhaps you could cover the bottom of the project in carpet, to sate the cat's needs. /snark
I would decry the desecration of good speaker grills, but the cat overlords at my house have free run, and would probably find a way to make me pay for such comments.

I think this is a dang cool project, and am wondering how it will be received visually by non speaker enthusiasts.

It's funny, my wife commented that "it's a lot smaller."

But it's not. It's just skinny. The speaker is nearly two cubic feet.
