Tastes are individual, fair enough, but their midrange suckout would surely show up on any frequency measurement chart as a huge problem if you were seeking accuracy.
It did leave me wondering a little just how such speakers get so many respectable reviews.
Is this not the same condition with photographs, or movies, or food, or wine. One can emphasize a particular quality, and by emphasizing that quality, or flavor, the person experiencing it will have a heightened experience which will be perceived as superior. A complex and well balanced oak taste to a wine can hide the fact that it is lacking complexity of other flavors. If you like oak, which many do, you may be enamored and not catch what is missing. Obviously good tasters will catch that, there are far more tasters and reviewers than there are good tasters and reviewers.
