I do ears and brain, not graphs and numbers. I don't know the measurements of the gear I've got here and I don't much care, I just know it sounds awesome.... But if people want them, they should probably be available, with the usual caveats....
Should Speaker Manufactures provide a Frequency Response Graph?
Eric at Tekton Designs has been battling two different reviewers who have posted measurements without his permission, using Klippel devices for their respective measurements.
It seems to me that if manufactures provide a simple smoothed out graph, consumers can see how much a speaker is editorializing with a frequency response that deviates from neutral.
