I mean experience with measurements not just rotating equipment. Nothing wrong with liking a non flat speaker (bass boost, rolled off, bright, etc). It would be worth understanding how that equipment measures and searching out that equipment. One man sweet highs are another man’s dull speaker and that is where standards come in and play a roll.
Resonances, uneven dispersion and driver miss matches are not what I would call taste differences. It is a short coming in the designs. Harman has a house tune too. It is 0.5db per octave drop from low to high.
measurement tools like REW are free and a mic cost less than many people’s power cords. Measuring the rooms/system response and doing positional EQ (moving the speakers/subs) can/will make a huge difference. Measuring decay time and adding the right amount of treatment really helps too.
I have a pretty large room and ended up with eight 7” thick panels and a fully treated ceiling to get my decay times down. That added far more clarity than switching equipment ever could have.
