A mate of mine just bought one of these active crossovers which is kind of old school but looks like a nice peice of kit. The problem we're facing is that the cutoff frequencies are set by crossover modules which have 7 resistors in them (kind of like audioControl's xovers). Unfortunately JBL's website doesn't bother to explain what the formula to calculate the resistance value should be... do any of you have a clue??
