After reading many of your comments I wonder if building materials is the prime suspect of preferences in target response.
I live in a house made of lumber and dry walls, a typical suburban single-family home in the US. Many of my audio buddies live in the cities in China and reside in condos and apartment buildings made of brick, mortar, concrete, and steel bar. I am not familiar with building acoustics, but my guess is that wooden houses are more absorbent and concrete buildings are more reflective. Their reverb characteristics should also be different. Some of my buddies mentioned that they can hear the "echo" of their hands clapping in their normal size room. I couldn’t recreate that in my house. From my personal experience visiting unfurnished homes back in China, I remember hearing echo/reverb quite easily. I have never heard such a thing when visiting unfurnished houses in the US.
I shared my downward tilted in-room response with my audio buddies and theirs with me. They thought I was a basshead because my target wasn't flat but tilted all the way up in the bass region. Interestingly enough, all of them were familiar with the downward tilted Harman and B&K targets, yet all of them chose to calibrate their systems to a flat target. Not all the way flat to 20kHz, of course, just flat to 1kHz or 2kHz and let the speakers took it from there. I tried the flat target at home and boy it sounded thin and bright to me. Admittedly I might be a basshead, but I believe the difference in building materials also plays a major role here.
It is really much more offending than any resonances I have in my living room, non-nearfield system. Thankfully we have relatively easy access to REW and PEQ these days
