Apologies for a slight hiatus this end. I received all my timber (at last) to build the big sub horns. In my sims they are still 101dB at 22hz so are likely going to be good fun lol. Yesterday I have been ripping all the sheets down into the different parts. This is an important part of the build because accuracy is paramount. Even 1/2mm out will cause headaches. I use a cast iron table saw from the 1960s - still extremely accurate and an absolute pleasure to use. Wouldn’t change it. Below you’ll see the cut panels - this is 26mm extremely premium beech rotary plywood with every layer solid beech. As a consequence it is extremely strong, very dimensionally stable, and heavy. You will see below a picture
of the cut panels.

In my build, I will use a contrasting timber on the front baffle just to break up all the beech and create some design interest. I am trying to determine what to go for now. I am veering in 2 directions - 1 would be walnut and the other maple. Any thoughts your end?
I was over at the timber yard, and like any timber lover, it is a dangerous place for the wallet - kid in a sweet shop type of thing. Anyway I spotted this whacking great single piece chunk of kiln dried iroko in 80mm thickness. Brought it home and made a very large and heavy turntable plinth - didn’t intend to get derailed by this but couldn’t resist lol. I am just finishing the French polishing now. The maple side cheeks were a pain because they were hand carved. It is hard to get perspective on this one because the plinth has huge bevel cuts underneath to make the plinth look like it is floating. In the 2nd picture you can see the bevels and m8 spikes. These can be replaced with any footer of course. Iroko is an exceptionally strong timber and very dense. It is often used now in the boat world as teak substitute. Great resistance to rot or damage. Tonally it is rich and full sounding

Back to subs. All the joinery is being mapped out now. Quite complex as it uses no screws and nails. Combinations of dados, rabbets, slots, tenons / mortise.
