[QUOTE="AlterEgo99, post: 6153762, member: 610253"] Did some Googling and think I understand the active crossover a little more... "By using active networks, many of the problems associated with passive networks can be eliminated. Unlike passive networks, active networks are comprised of solid state electronics that divide the audio spectrum BEFORE amplification. Since these networks contain active components such as transistors and integrated circuits, they are sometimes referred to as "electronic crossovers". Performance is just one of the many key features realized by using an electronic crossover. Since the filtering process takes place prior to amplification, there is no insertion loss. Also, since the amplifier is connected directly to the load, there will be a significant improvement in damping. Distortion will also be reduced since the load that the amplifier "sees" will be less reactive. Isolation is another benefit active systems provide. What this signifies, is that changing the impedance of the load will have no effect on the crossover. This is not the case in passive systems where the crossover itself is designed around drivers with specific impedances. If these impedances change, crossover points as well as filter Q and thus response shape and damping will change. Perhaps the most attractive feature offered by an electronic crossover is it's flexibility. Almost all units of this type allow for the continuous selection of crossover points.
