Dunno, it seems to overcompensatethe level but still drops off top end early when compared to real world. I will stick to using the constant directivity assumption and estimate an octave or more extension.

I think directionality is only one factor affecting high frequency response, and Hornresp still uses mathematics of "mass rolloff", which cannot be acurate whilever a speaker is NOT a flat plane rigid piston.

Still cut-and-measure for me.
