Rather than half-shpere, how about half-sonotube? A large diameter tube. Provides "automatic" wings without a "flat" surface.

If the tube diameter is not minimal(almost no baffle) then it's the worst shape regarding diffraction:

"The absolute worst enclosure is a circular tube (cylinder), with the driver mounted in the exact centre of an end-cap"

Baffle Step Compensation

EDIT: aha now I get it, you mean mounted on side of the tube...

I'm not talking about mounting a driver in the end of a sonotube. I'm suggesting that the driver be mounted on the SIDE of the tube cut to be half-round.
