HI Widget,
Thanks. I've checked the forum and remembered you had made TAD and Westlake horn for 4001 use. Are these still available?
Also is there any wood horn there for TAD 4001 that can let me crossover it at 350Hz (which is the actual KHorn crossover freq even they advertised for 400Hz)?
Can TAD 4001 go such low?
If it is OK, I can use my existing TAD ET-703 the very excellent tweeter (that i used for many years which replaced Khorn's K-77) to crossover at about 14 Khz with TAD 4001.
