Hi all,
I'm modelling midrange horn with phase plug into hornresp. I have some question.
If I put the plug into the throat chamber I have to decrease the Vtc (Vtc - plug's portion in the throat chamber) but.. have I to decrease the Atc too?

When I model a plug, I think of it as not being there but regard the areas and volumes in questions instead. Remember that hornresp visualises the driver as being a perfect planar diaphragm. I alter Vtc, Atc, and horn sections that the plug sits in.

So hornresp wouldn't see it as a plug, but rather a very small throat opening and small throat area. Is this correct?
