Troels doesn't seem to mention dipole in the article (unless I missed it), for that is what the speaker almost is, except for the tweeter, ideally that should be dipole too

Just yesterday I stumbled upon this thread on OB materials, and some interesting options are mentioned here:
Wood for OB speakers

Hope it helps.

Open baffle speakers have a dipole polar response and it's important to understand how this effects the room and placement

Instead of opening a separate thread would a live edge slab work for OB? Minimum size would be 20x40 but wouldn't necessarily be perfectly dimensional and would not be a plywood. Large selection of wood slabs, many species to choose from Or would something like this ring or have a tone of itself. If so would laminating a plywood as a backer solve some of this 'tone'?

Check out the prices!

I have managed to find baltic birch ply where I am and have started the build with it.

Thanks all.

Solid wood can be a good speaker building material, but you have to know what you are doing. If it is one big slab, you might need to reinforce it to keep it from warping.

I have speculated about doing OBs with some western red cedar slabs i had on hand (i gave most of them away for others to use), and looked lustfully at some slabs made by a buddy: Urban Milling

Thanks folks. I looked at some prices. Some not so bad, some up there. I have some rough sawn Black Walnut. I should probably just take it down to the local cabinet shop, have it finished and glued to get my width. Same wood as this turntable base. And I'm not a woodworker and would be a waste of good money to try and use a slab.
