They have always been sold to the public as speakers the mastering engineers use. Many do.
Even if the B&Ws were flat (and some are more than others) then you might think them unmusical due to poor quality recordings/and or poor reproduction chain. And then there's the possibility that flat frequency response is not all there is to speakers sounding like music (or not even the primary quality).
Voicing speakers is very tricky and the one size fits all approach does not work. That's why there are 1,000 speaker manufacturers out there, and 1,000s more in garages. I say, if you don't like the sound, make your own!
