    Default My new horns

    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.

    Paul, exactly as you described. Using dowels for transferable datums to allow me to machine both sides.

    Looks like fine craftsmanship but they do bring to mind medical school teaching aids!
