hi
follow this good article, i start with measure the impedance response of the woofer and tweeter, then i calculate the RCL need for fix the response.
again i measure with the RCL (tweeter) and RC (woofer) and i get flat response.
my problem is when i add the 2nd crossover network to the simulation, the impedance response not good again.
example in the pic,

Your tweeter crossover looks to have a 3.6mH ? value, Why so high? For a normal dome tweeter in the ~ 2KHz XO range - you'd be looking at between 0.4 - 0.6mH for your typical 2nd order. With such a high value inductor, you could be bypassing your resonant peak compensation.
What resistance values have you loaded against your inductors in your simulator?
PS: Why are you adding impedance and resonance peak compensation? (loaded question)

hi
the tweeter is horn down to 500hz. but its not about the filter is about the impedance.
i think maybe its normal:
the all point of the zobel its for the crossover "see" flat impedance response
the impedance in the graph is what the amplifier "see"
what do you think?
thanks
