I was inspired to my horn project by Jack DuMoulin who built these wonderfull babies:
- 150Hz free space mid-bass horn for Electro Voice EVM12L
- JBL 375 2″ compression driver on a 350 Hz Tractrix Horn by Bruce Edgar
- Fane ST5022 ring radiator tweeter
He also gave me some helpfull adwise.
So, thanks again Jack!
