Its important to remember that most musicians and mix engineers are NOT audiophiles. They neither belong in our world or understand it. Most singers, musicians and artists do not own audiophile equipment they know nothing about what we do. This is the reason studio monitors can be so different than audiophile type speakers. Studio monitors are designed to fulfill different criteria. Often these studio monitors are placed in huge rooms. If so you need big 18 inch woofers and 10 inch mids with massive horn tweeters. Polar response is less of a concern for studio monitors since the room is assumed to be treated. Musicians like their speakers to go loud. Its quantity over quality. They often spend years performing on stage where their ears have been punished by excessive sound levels to the point where they wouldnt know audiophile sound if it hit them in the face. Consequently studio type monitors are not suited to the delicate and refined tastes of most audiophiles.
Mastering studios are where you are more likely than not to find these audiophile type speakers such as TAD, B&W etc
ATC is another speaker that was born out of the need for speakers to go loud in a studio environment. Furthermore, they know nothing about speaker design since they started off as a driver manufacturer. Unsurprisingly, ATC speakers are mostly wooden boxes although they have been known to occasionally use metal. They also rely on testimonials from people like Brad, than measured performance to sell their wares. ATC is a marketing company. Neumann monitors do publish fairly detailed technical specifications and measurments. However their speakers are tuned ruler flat which is not suitable for home use.
The Neumann use multi drivers in wooden boxes so will suffer from all their inherent problems such as lobing diffraction cabinet resonances and back end distortion.
There is no substitute for testing a speaker than using a human being with refined hearing such as myself. If I was in charge, 99% of these speakers probably would not pass my intense standards. No speaker company will employ someone like me because none of their speakers would ever be good enough.
