Give it a try.

Back to the guestion between flat DI or slightly rising one. A paper was posted on another thread
https://www.sausalitoaudio.com/wp-co...ama-Charts.pdf

And a quote from page 17:
"... if the axial response is substantially flat,
the inverse of the directivity index gives a useful approximation of
how the speaker will measure in a room – of any size."

If this is true then people who would like a bit downward sloping response on a speaker would prefer the slightly risin DI waveguide since it would have downward sloping power response? But, when the DI is flat, the power is also flat if the on axis response is flat? This one would be outside of the circle of confusion, the flat?

If the axial response is substantially flat, the inverse of the directivity index is simply the power response. This is not the same as the in-room response but close.

Sure, this is still the same debate we had earlier. I'm only not sure I follow what you say of being "outside the circle of confusion".
