I finally got around to playing with Marchand active crossover. Something seemed missing until I realized that the passive crossover is still in place. I looked inside the bottom woofer. Am I suppose to disengage the two jumpers on the board behind the toggle switch? If so, what is the best way to disengage them since they seem to be soldered? Thanks in advance and I am on this board to ask since I am assuming that BC is on vacation through next week.
