Spent a bit more time smoothing out the throat transition section. Also calculated the center of gravity for the whole assembly.

Private labeled - Can't talk much about it. But, it's one of the best sounding small horns I've ever heard. A few sneak pics for fellow Havenites!
Working on a 500Hz version. Same body, two swappable adapters. One for the standard Altec 80X drivers; The other for the Altec 288.
Sorry to disappoint. I do not make reproductions.
No worries at all! Been admiring your work for some time.
As seen on social media.
