A different sort of Multi-Cell horn. 3D printing.

Beethoven's ear trumpets from the pre-electronic era:
Believe me, that's the first thing I tried, the second was stereo! The didn't seem to have much sound or change much except the background noise.
The only audio the horn has been used for is talking thru it and playing a cellphone thru it. It again seems to have no particular sound.
 
shorten the walls that form the outer perimeter to get the soccer ball exit.
I did that with an all hex cell version, basically cutting the walls to make a spherical mouth of the same radius as the length of the horn. I think it's a good option and not too hard to do, though it does cut back the outer wall a good bit. Is that a better way to make it than the soccer shape? I don't know.
 
@Hearinspace I think this is what you are thinking of, all hexagonal and with straight cells. This is a first look. This is made with the mouth in a spherical shape. Normally hexagons (and squares) don't fit like this, they want to be flat or have spaces between the cells. But I managed to get the walls to all touch, no gaps between them.
