Using a variety of techniques - some of which were outlined earlier in this thread, diffraction based response anomalies associated with the use of "boxes" can be essentially eliminated. The measurements don't lie. And one of the smoothest measuring speakers ever made for home audio is NOT shaped like.....(gasp)... a sphere.

It's not often you hear John Atkinson say things like "Good grief!" about a speaker's ruler flat response.
" Note also that the JBLs are generating full output down to 25Hz. But, good grief! Look at the in-room response above 200Hz: It is extraordinarily flat and even, falling within superb ±1dB limits other than a very slight boost at 2kHz. "
This is clear, unambiguous, and convincing evidence that the issue of diffraction related anomalies can be eliminated to the point of inaudibility in NON SPHERICALLY shaped loudspeakers. The same cannot be said of true spherical loudspeakers which in the current highest expression of the art form, still exhibit uneven response despite the assistance of full digital equalization. Theory and practice are not always on the same page.

Building a limited bandwidth and limited dynamic range loudspeaker and equalizing its response to create a smooth graph and prove a point is one thing. Building a real high fidelity loudspeaker that exhibits truly exceptional performance in every respect is quite another.
