Acoustic Horn Design – The Easy Way (Ath4)

Hi Marcel,
There's really a great potential in using large-format drivers at their phase plug exits, even if radiating e.g. through a 1.4" aperture.
Can you please clarify- do you mean to use the 1.4 in driver directly at the horn sans the throat extension, or with a throat extension?

I am asking as I have two drivers, a phase plug of which terminates at the front face of the driver.

Kindest regards,

There's simply something to the "full-bodied" reproduction from one driver. You won't hear that very often.
1.5 a/b Ratio at the mouth, Cutoff; 150hz F3, with the mouth height no bigger than 700hz.
