I see the 4425 schematic has two sets of level controls. Does anyone have a chart showing the transfer characteristics of these controls? It looks like one changes the crossover frequency while another adjusts the level. Or they could be contour controls.
Either way I am working on a crossover for a 2214H monitor and I am curious to see how this crossover works.
Also, there is 50 ohms of resistance across the woofer in the schematic. This is more than the L100T used (39) and I was hoping someone could tell me why they used this resistance across the woofer without a capacitor in series. It does not resemble a Zobel in the true sense.
