With curved sidewalls and a curved bottom for the well, I don't see how that reflection would happen...

That said, I would imagine that there must be similar router bits that are able to cut square-bottom, sheer-sided grooves, rather than rounded ones... ? Of course, the bit would have to cut to the exact correct dimensions...

Well, yeah.. I suppose! As long as the "mixing up" still follows the math behind how diffusers work. You can't just use any old random shape....

Just like one made out of any other material, actually... It's not the material that causes the diffusion, but the carefully crafted shape.

Thank you for some real answers! very cool.
