Lakelover, yes, they’re curved. I built them with an internal frame similar to how an airplane fuselage is built. The frame is interlocking and very rigid, then I bent layers of 1/4” Masonite on the frames. There’s about a half gallon of glue in each pair. The front baffle is made up of two layers of 3/4” MDF. These are extremely rigid, much stiffer than a speaker made of just 3/4” MDF. The curved sides keeps the Masonite under tension which makes them even stiffer. They weight between 80 and 120 lbs each depending on the model. I used 4” ABS for the tweeter mount on the top, I then filled the edges with fiberglass filled body filler, primed, sprayed 4 coats of urethane and polished them. When they’re running you can’t feel any resonance in the cabinet no matter how hard they hit which is a good thing.

Sorry about the blurry pics but these are the only ones I could find of the frames. I posted a couple pics of another model I built so you could see the curves. I built many of these and made each pair look a little different.
