Really, EQ is a linear change so unless we are dealing with compression and such, its effect should be similar to simulation.
If this is the case, and these simulations are pretty close to reality, and you can achieve a large improvement in a short time with a small number of adjustments, why wouldn't the designer of the speakers in question make the changes? Talking purely about actives here, of course. Though even with passives, it seems like the manufacturer could include information to help you EQ.
I mean, the scores above are arguably as good or better than a Genelec 8341A, starting with a considerably worse baseline in terms of hardware. If it's really that simple, why isn't everyone doing it? Or is the preference score really not reflecting reality when used this way?
