Hi werd,
I suppose if a musician have a chance to take a look at our discussion he will be laughting for hours on end.This is just stupid. In poffesional area mixers,EQ, active crossover are the most comman. You will not find a passive speakers or very rarely in studios, concert halls, stations. Just because it is not profi orientated passive speakers are so comman in our homes.
I am frequently asking a friend of mine who adores Dynaudio, why in his car he uses active milti amplifiered drivers and stay single connection in home. He has Dynaudio Countur 3.3 with a single binding post and all profi oriented speakers are ether miltiway connected or multi amplified.
The world around us is not only black and white, there are all other colors.
Maybe for some speakers or amplifers the difference is not so obvious, but there is a difference.
On this subject you can look for John Risch articles and studies.
