A few years back I built a parabolic horn with JBL 2226. It worked well so I have continued working on such designs.
I got a request from a guy in Canada, so I used my improvements on a new drawing.

It seems like the ":" after "https" went missing in your link ;)

Thanks Julian. Fixed. The interface is a little bit odd :-)

If you want access to the cad file you need to download from diyaudio.com. The file type is not allowed here.

Would you care to render a few pictures? Some of us don't have access to cad software......
