A study of regular polyhedra reveals the tetrahedron (with drivers on each face) to have nearly spherical dispersion.

I was wondering if the same, or even better dispersion could be achieved by placing the drivers at tetrahedral angles on a spherical enclosure for more volume and to avoid diffraction at edges.

I’m designing an omni at the moment, first I thought to simply use the tetrahedron atop a triangular bass cabinet but the thought of bettering the design with a half sphere with three drivers at 19,47° angles from center of bottom and 120° from each other seems plausible… Though obviously a bit difficult to construct.

The three drivers do need volume and spherical geometry would maximize that.

Thoughts?
