this is a jig I made to smooth the column out.
lesson, no matter how perfectly you cut an align a layered construction.....it will never be perfect.

I was racking my brains on how to cut the column into perfect 3rds and this is what I did.

this is the shape of it.
it's not glued, just leaning against each other.

Wow, there had to be a lot of easier options for that than layered plywood, but I'm happy to see this back in progress - I was pretty curious about how well my napkin-style guesses corresponded to real raw driver measurements in that arrangement. I could simulate it, but gosh, what a pain that would be .

P.S. you like those rail clamps (post #85)? I have a bunch of those, and while I could imagine a superior version, they are sort of my favorite tool; I use them for so many things.

I just discover this thread. Has the speaker meanwhile been built completely?

 

[Melo theory]

No, I'm actually waiting to find some Dayton 12" waveguides.
They are discontinued.
I have to 10 inchers right now.
