I want to change the original passive crossover of my Canton RC-L, to suit active bi-amping. I've got a schematic of the filter, and after opening up the cabinet, I could identify the parts. The problem is that I don't have experience with PCB's. I don't know where the signal goes from the input. I tried to attach the schematic and some pics to this message, but they were too big. If anyone knows anything about it, perhaps I could send it to you?
