@amir_asr In my hypothesis, I was attempting to point out that IF a speaker was ever designed that could sound like what people (including you) believe to be as close as possible to the sound of 'real' instruments in a 'live acoustic space', and if this very same speaker measured poorly; people like yourself would point to the measurements and not believe in what their very own ears were telling them!
This does not exist. It cannot exist. You are saying you want to be in the two places simultaneously. Again, what extensive research across many decades shows is that we as listeners prefer accurate and neutral measuring speakers.
This is no top of your premise that people thinking some speaker reproduces real instruments from a recording that itself is not such a copy.
You can't make up scenarios that are in conflict and don't represent reality and then draw conclusions from them.
But let's say what you say is true. Then what you call "bad measurements" are the measurements we want to look for in speakers. In that regard, those measurements would be considered good, not bad.
This is fundamentally where I believe we differ in our approach to music reproduction. You are seeking something that you believe looks right on a scope, or with the measurements say is what should be 'musical', whereas I am looking for a product that can reproduce the closest to what my recollection of the 'real' sounds like.
Not remotely the case. I listen to every speaker I test. I have already said that measurements are about 80% predictive of speaker performance. That last 20% such as directivity is not quantified.
The difference between us is that I believe in comprehensive research into speakers says that we can easily rule out bad speakers with measurements. That if they measure poorly as you say, we can conclude with high confidence that without other biases, majority of listeners would not like such a speaker.
As a former pro musician, I may have a bent/bias on what that is, but it also has allowed me to be exposed to numerous instruments and their sound in varying venues. If a product meets with my expectation of this sound, and still measures poorly, I have no concern on this.
That's fine. Have your personal belief. Come back when you sit in a blind test and your beliefs prove to be reliable. I have. I found that my beliefs were NOT reliable in that situation. I repeated it. Same outcome. What happened? I voted just like majority of listeners situated completely different than me. So I had to throw out my own personal notions of what is correct and listen to what science says.
OTOH, if the product measures well and does not meet with my musical expectation, I am not interested. That simple.
Wouldn't be mine either. Again, this is why I listen and occasionally go against the measurements and recommend a speaker. Again, it is OK to fall in the 20% bucket. But don't say the science knows nothing about this domain. We know a ton. A ton. Dispute it at your own peril.
