[QUOTE="gstokes, post: 8279946, member: 660947"] Maximum Damping Factor.. in a "normal" system with passive crossovers and multiple speakers per channel the amplifier must work very hard to control each driver, not only does it have to control more than one speaker per channel but it has to do so through an unpowered or passive crossover network containing capacitors inductors and resistors, this passive network between the amplifier and the speaker makes the job of controlling the speaker/s that much harder for the amplifier. Going active is simply eliminating or bypassing the passive crossover networks and using each individual channel to drive only 1 speaker, now the amplifiers job of controlling the speaker is very easy because not only is the passive LCR network out of the way but the single channel has only a single driver to control, the amplifier now has maximum control over each speaker or Maximum Damping Factor. In a passive system the only component\s the amplifier can "see" is the crossover, it can't see the speaker/s, when we remove that passive network we remove the blinders off the amplifier and allow it to "see" the speaker, now the amplifier has a clear view of the speaker without obstruction and is able to easier control it, hopefully this makes it easier for the layman to understand why active is better than passive. There are many reasons to go active but i would think that maximum damping factor would be the most prominent reason and would make sense why active systems have the potential to sound so much better than passive systems.
