@amir_asr You have not considered in my example the fact that all who heard this speaker found it to be the best that they had ever heard. Is this possible in real life, I believe it is, as we have examples of gear that sounds great and yet measures poorly. (For example, a number of low powered single ended tube amps).
In my example, i would state that the measuring devices are simply measuring the wrong things, and not that the speaker is in fact inherently flawed. Your reply tells us this ( the opposite)-- you believe the measuring devices are in fact perfect, and that the audiences’ hearing is in fact flawed. This is why I think there are other members here who are taking you to task, they do not have the same absolute belief in the results that your measuring devices deliver to always correlate to the sound that gear produces.
One thing I do agree with you about--100%, and it is this, IF everyone hears a piece of gear that sounds poor to their ears, and also measures poorly, then it is a service to disclose this aspect to the a’phile community. Folks still need to hear the piece for themselves before making a purchase decision, but the fact that it performs poorly and yet is touted by the manufacturer/dealer can be possibly explained by its poor technical design. ( which is again why i believe that the measurements JA performs for Stereophile have definite value).
