I love those graphs! The phenomenal variance in frequency response above 1KHz between those two, measured with what I would presume to be reasonably accurate ways of registering what the ear picks up, would have to frighten the life out of anyone who believes that a DEQX modified world is the only one worth living in ...
And I note those two are highly regarded transducers. Thank God the ear/brain is so tolerant (where did I see that before ...) !!

They are nothing compared to the kinds of variations you see in room response. The ear/brain adjusts quite well. I, for one, do not challenge that part of your position.
