The Acheron, p3

What’s the effect of the nonideality of the gyrator? For convenience, here’s the gyrator equivalent circuit again: With the reactance of the inductive part being about 100k at crossover, the series resistance can be chosen; too low, and the opamp will be...

Yes, there is a Third Way. And that is based on passive filter design. The sins of passive speaker-level crossovers are many; after all, these networks are dealing with highly reactive loads at high currents. Not so a line-level crossover, which will have a nice...
