I am a huge proponent of active obviously but i also have to accept that a complex (expensive) passive crossover can achieve almost all that an active system can. You would not see that in a professional monitor.
Most of our cherished music was mixed on passives complete with all those little elements as well. They couldn't work hard to keep them there if they couldn't hear them.
You get frustrated that passive just smooths all this information over, covers it up in the background, the mix now is somehow missing the little elements the artist and mix engineer worked so damn hard to put in there for you, but content wise it sounds very similar.
@donavabdear , remember I wrote a long time ago now it seems that low distortion, accurate reproduction takes getting used to but once you do it's addictive and you can't go back? What @lonemountain just described was exactly what i meant.
