So I want to build some n1201-8a for some cabinets. I want to make them bi-amphibole or at the the very least bi-wired. But when I look at the schematic for the n1201-8a I am confused. If you follow the negative leg of the woofer you have a .3 inductor, followed a variabled resistor, to a 8 mic cap and a .77 inductor. How do I replicate this in a bi-amplical situation ?
