I too, hear things with speakers that can not be fully explained by the measurements. But this makes me wonder whether the measurements fully describe what I can hear, and whether there is some gap in my understanding which is where the explanation is hiding. For years I have wondered why some speakers sound more dynamic and effortless than others. The answer is actually in the measurements, just not in the standard measurements that we take. You have to measure the speaker at different SPL's to get your answer. Some speakers compress at high volumes - that is why they sound like they're struggling when they have to reproduce a loud transient.
That realization made me think about what else I don't understand, and there is A LOT that I don't understand. Like why two tweeters with the same frequency response can sound different - one sounds like it shimmers, and the other sounds lazy and dull. Or why big subwoofers have that "big subwoofer sound". I am convinced that both phenomena are real, and it's not just expectation bias. The answer is there somewhere, and one day I will find it. I don't think that the measurement doesn't explain it, rather it's my lack of understanding.
