Would the two different speakers even have to be electrostatic vs dynamic?

What about two dynamic speakers... say Paradigm vs. B&W?

If speakers measure the same exact frequency response regardless of the brand, does that make them all sound the exact same?
No Sonnie, I simply used as different examples as I could find to 'magnify' the question so to speak.

I get different answers to my question, depending on how i analyse it!! Take the 'hidden behind the curtain' example.

We don't know what is there, so can treat it as a black box, we don't care what happens inside it, only what comes out (bit like an amp black box). What comes out of it are waves in the air, which impinge on our ears. So, a given FR will sound a certain way, so if each time I take a measurement prior to listening I see the exact same measurement (even tho the demons have switched speakers behind the screen without my knowledge) I can believe that I would hear the same sound.

OTOH, surely surely a FR measurement will not take into account factors (intrinsic to drivers) of say transient response?? So a dull, boring lifeless speaker driver could theoretically have exactly the same FR (with dsp if needed) as a dynamic, exciting and energetic driver, so the two would reproduce music very differently no matter how close their measurements.

See, I'm confused, and it doesn't take much ha ha.
