Acoustic Horn Design – The Easy Way (Ath4)

@mabat, would you consider designing the necessary adapters for the B&C DH450 driver? Due to its small size, it has a unique mounting pattern: two M5 holes 180° on a 57 mm diameter.I just ordered three of them and want to test them on various ATH designs. It's pretty impressive that the recommended crossover frequency is 1k Hz for full power. If needed, B&C says you can go as low as 800 Hz in a home setting. I would be happy to make the necessary purchases on Cults. Thanks for the consideration.

Finished one! Not perfect but good enough for me - I did metallic white in the end so it has the mica flakes

I already posted some measurements:

BTW, the Tritonia mounting flange is already designed for the DH450 mounting pattern as well.

Mabat,
After looking through here
For BMS 4592nd Coax I would need E520G2 wave guide and T520-4552-EXT if low frequency capability is needed, correct?
Thanks,
No, 4592ND is a 2" throat coax driver, completely different from the 4552, not interchangeable. In general, I don't encourage to use 2" drivers, so the only available adapter is the T520-50-STD-1 (just for completeness), but use it on your own risk 🙂
 
Thanks @mabat. I just purchased the adapter file on Cults. The 16-ohm DH450s should be here in about a month. They only stock the 8-ohm version here in the States, so they had to come from Europe. I'm hoping they will arrive in the next 4-5 weeks.

I just installed the inserts for the 280EX-MK2 mounting bracket. This went quickly using a pencil soldering iron; they are well designed.
