I guess I'd favor the summed room response, given an ideal room. it
seems to me that in a control room, only one person gets the on axis
response, but everyone else gets the result of the power response. It'd
be nice if both were nice and accurate, but I think it's better overall
to have flat power in most situations.

Thanks, makes good sense. I had hesitated to trust my intuition
based on more ordinary speakers in more ordinary rooms, where I
have still only drawn some murky conclusions.


Of course, I'd love to hear some reasons why this might not be the best
approach!!! I'm coming at this from working with a speaker that has
little/no crossover anomalies and no significant beaming, so perhaps
this viewpoint is not applicable in the real world of multi-way cone
speakers.

Yeah, rub it in. Arf.

For anybody interested, the argument for flat on-axis response in
multi-way speakers is that the direct sound from the speaker arrives
first, and so is given a significance by our hearing. (It's also the
loudest, which can't hurt.)

The penalty in conventional multi-way speakers is non-flat summed
room ("power") response. FWIW, the D'Appolito geometric removes
this penalty.
