Hi guys, this wide dispersion short throw horn here:
Selenium HC23-25 1" Exponential Horn 100x40 1-3/8"-18 TPI
or
Selenium HC23-25 1" Exponential Horn 100x40 1-3/8"-18 TPI
(same horn)
If I had a machinist make a short 2-4" extention at the throat, would it increase the projection? (throw) even if the very wide 100 deg was reduced a bit as a result?
This is for an emergency PA type - not concerned about fidelity.
Hope someone's tried this before!
Regards

No.
No.
Well thanks - but is that the result of any lack of taper?
TOA make a (long) long throw horn with a very gentle taper before the more abrupt mouth opening flare.
That's why I am surprised there would be NO improvement in distance with a straight extention. Is there a minimum length necessary for this?
Also I asked if there would be any detriment. If not, it may simply make construction easier.

That horn has no real pattern.
With the long axis vertical, it will have broad dispersion in the horizontal plane.
Grafting a tube onto the horn entrance will do nothing to control dispersion.
Dispersion is controlled by the angles the horn walls are set to. Mouth size, taper rate, and depth determine how low control is realized.
