I'm hoping someone can answer a Qu I have.
We often see wicked impedance and phase plots for various passive spkrs - which make them a difficult load to drive. So you need an amp like a Sanders Magtech, to make them sound their best.
My question is ... if a passive spkr which has a wicked impedance and phase plot is turned into an active spkr - so:
* using the same drivers
* but having an external active XO
... will this change the impedance and phase plots?
IOW - are the highs & lows in the wicked impedance and phase plots caused by the XO ... or by the drivers themselves?
Thanks,
Andy
Follow Ups:
The impedance curve of a typical speaker is a combination of both the drivers (and box, if there is one) and the crossover.
I don't know why a "wicked" impedance curve would be handled any better by a Magtech amp, than it would by any other good amplifier functioning as a voltage source.
The closer an amplifier is to a voltage source, the closer it is to being load-independent.
