>What I meant is that bullets have a 40deg...dispersion
Some do, but not all. For instance,these are 80 degrees:

Like all horns the angle of dispersion can be tweaked with changes in the horn geometry.

I'm not familiar with those.
The ones I'm familiar with are those made by JBL, Beyma and FaitalPro which all have 40 deg conical dispersion.
Anyway since I do not know all available bullets I used the phrase 'tend to' in my first post.
The so called bullet,,,do not have a phase plug,,,If you slice the socalled bullet in half,,, you will see that is is a circular HORN some call it a ring radiater but it is a true horn,,,My JBL 075 has a dispersion of 90 degrees
I used to have 2402s which have a dispersion of 40deg.
