No. The
amount of honk mainly depends by how much a given horn is pushed to work at its lower
working range. When I give examples, in it entirely in the context of horns
which have been high-passed at least one octave higher than the horn is able to
support.

To have a
situation where there are no reflection surfaces, the compression driver must
be radiating directly in the air. Loading it with a horn is equivalent of
placing reflective surfaces around the exit of that driver.

That’s because
the wave cannot escape until it reaches the mount of the horn – it is
surrounded by all sides. But that happens only at the lower working range of the horn. When
you play some HF tones in let say 440Hz MF horn, the wavelength of these HF is small in
comparison to the horn’s diameter and you have a lot of random uncontrolled
reflections. If you don’t want to have reflections in the upper part of the
working range, then you have to eliminate the horn surface, which means to
eliminate the entire horn or to use it no wider that 1 octave.
If I have
to be fair, right now I’m not able to feel the horn smell, because the smell of
my pillow completely overrides it:-)
Good night,
