Is there a formula for determining the ideal depth of a waveguide or horn on the basis of mouth and throat dimensions?
I am considering building a horn/waveguide optimized for constant directivity not loading. |

I think most would suggest a O.S. waveguide. then the waveguide dimensions and depth are set by the formula.

That's it. When I first saw that, I thought it had to be more complex than that, but it isn't. For instance, a conical waveguide measuring 90 x 90 degrees will have a beamwidth of 90 x 90 degrees. |

Throat radius, start angle, asymptote (end angle).

Eg. 0.5, 0, 45
for a 1" driver, 0 for a dome (otherwise the compression driver exit angle) |

May be easiest would be to just use Hornresponse for calculation of your WG. Hornresp can do OS-WGs and will export dimensions in xls (or csv) format (do not remember exactly).
If you want to optimize for constant directivity, you either have to start over with simulations, or build and measure.... Both may be fun. |
