Hi Lee, thanks for interst, I have a preliminay drawing that my freind Dieter made of it but it is not competely dimentioned , I could get him to finish the dimentions as they are now. It was one of the more simple cabinets I have made as all the interior panels are the same width so you just rip your plywood all at once. i made it to cut nicely from 5x5 sheets baltic birch 18 mm 13ply , no screws, all bisket joints (200 in all)
the matierials are 3 sheets 5x5 18 mm baltic birch AA-AA grade , each cabinet so 6 sheets for pair. The horn starts under the driver and scrolls around the compresion chamber. The interior throat section is made with my sand composit and requires a mould made of that. I didn't take any inside or building pic.
I will be building two more and I can take some inside shots then.
here is a preliminay drawing ,,, "Bentwood Goliath Horn" siesmic warrior
Oh and the drivers are new factory fresh cones , my neighbor was owner of the local JBL dealer so I got the real mccoy
