Unsound, since neither anechoic chambers nor the measuring equipment nor the techniques used are standardized, how can that possibly be a baseline? All anechoic measurements tell you is the singular "performance" of a speaker in a singular environment that could not be more removed from its intended usage.
Our understanding of acoustics has progressed significantly since 1940 but old "standards" die hard.
Sound as we experience it is naturally reflective and therefore IMHO the fewer the compensatory devices (passive, electronically processed or whatever) necessary to allow a transducer to sound natural the better.
When Steinway voices its instruments with anechoic chambers or they carpet Carnegie Hall I'll capitulate and jump into the void.
