mijostyn - This is fiesta75 or maybe there is a fiesta25 too. I've been active crossover bi-amping for a couple years longer, but that's not the point. Seriously, you should know by now that an active system is superior in ALL resects, that kinda why you are bi-amping. In this most recent post you indicate that your speakers are active, I understand that. They are plug & play, not really an active SYSTEM. You say the "brilliance controls" are what would get burned up incase of an amplifier failure, isn't adding a control or resistance after the amplifier outputs counterproductive? Is it a digital control? An active bi-amp system is with the crossover at the INPUT of the amplifiers and nothing but wire after the amplifier outputs.
A passive bi-amp system is with the crossover after the amplifier OUTPUTS. Your system has active speakers, the crossover could be active or passive, correct? So which is it, do you know? It seems like you've been at this long enough to realize that a system with an active crossover sounds better than a passive one. PS. I totally agree that the best crossover is no crossover.
andy2 - As for phase shift you understand the concept correctly, capacitors add a 180 degree phase shift. But when they are coupled with inductors and the variable impedances of drivers the entire "system" becomes unpredictable and only roughly stable. Phase shift will not remain constant with the changing frequencies. That's another reason that doing the crossover at the INPUTS of the amplifiers is better, so much more stable and predictable. I'm not wanting to argue, just trying to convince some people to try a "real" active bi-amp or better yet, tri-amp system that allows YOU to make some decisions on the sound outcome. Best to all.
