Just in case anybody was starting to think I am only on this forum to sell things...
This is a project I have been doing on and off for a couple of years, although it starts a lot longer ago than that. To improve the vertical integration of my speakers I decided to change my 200hz LCleach horn from round to oval. These are the prototypes I made. I have laminated them from birch ply ( utilising my offcut stock). These are 200hz horns too, approximately 700mm deep.
Before I could build them, I had to build a cnc router, and learn how to program in 3D NC code too.
They have been sat in this unfinished state from just before Xmas, as I have been ill since, with a chest infection and do not want to make it worse currently rasping and sanding, which is frustrating.
