I will have to give this some of the thought it deserves but, in the meantime, my first response is that the market for such a speaker would be:
1/ extremely small in the first place
2/ dominated by brand names, because engineers typically take comfort in the fact that a large corporation with massive resources designed the thing. Clients do to a lesser extent as well, and engineers' choices can be influenced by what the client thinks of the brand in question. Another example would be Neumann microphones. They have become so thoroughly associated with the "big time" studios that many knock-offs look just like them.
Currently popular (and respected) brands for serious monitors are Genelec, Westlake, Tannoy, B&W, ATC, Harbeth (in England), PMC, Dynaudio, TAD and Lipinski (Sp?).
One rung down would be JBL, Mackie, KRK, Blue Sky and NHT.
