Some five years ago, I came across a post from someone in England building new a set of Voigt Domestic Corner Horns. I was hooked. Unfortunately, I had no access to a real set nor any drawings with dimensions.... Also, pictures of the horn were scant and very hard to find. Recently, I was in the fortunate position of having access to a home CNC machine, CAD software - leaned how to use it, and a 3D printer. Game on.
Created the model below in SolidWorks.
Many details and dimensions were "made up" since they were not known to me. But, I decided the right thing to do was to build a half-size model just to test things out and learn in the process. My goal is to build a full size speaker one of these days. I estimated from various internet images that the real speakers stand around 5'4" or so. Also, my preferred speaker build material is baltic birch plywood.
The original horn throat was cast concrete. My solution: 3D print the mold and casted it in my kitchen sink. (Wife did not know )
The top diffuser was modeled and cut in pieces on my CNC. Then glued up and hand sanded.
The quarter horn is made from three sections.
The bass channel was very tricky to build: Out, up, over, over, down then out from the bottom of the front.
Looking down the throat. The grey part is the concrete reflector.
So far, I've only built one. The diffuser, horn pieces and the concrete reflector for the second speaker are already made.
After five years, I've finally got it out of my head.
