How did you calculate that one erhan?

cutout frequencies are determinating and z impedence is taking in and this result is there inductor and capaticor. ı'm creating a list. in this list crossover's cutout frequencies z imedences and capacitor's capacity inside. comnig up some days. this circuit is the original. but if you get the list and you create own crossover and intendent frequencies and intendent gain.

handrich, this passive crossover from apogee sound's this is very very good and robust system's equipmets and ı don't know cutout freuqencies but they uses 2'' compressions this is means that hf cutting is lower... maybe 1200hz
