could someone explain me whether adding a second order crossover ina threeway speaker change the final driver impedance. if yes then how to calculate it?

I tried to find an answer but couldn't. I don't have engineering background so can't do it logically( I am a critical care specialist)

what i know is how to calculate impedance when speakers are connected in series or parallel but cannot do it when crossover comes into circuit. so i am stuck on basic design itself.

for e.g., if i want to use 8 ohm tweeter, 4ohm midrange and 4 ohm bass driver with second order crossover(low pass: around 250Hz , bandpass 200-6000 and highpass 4000-20000.) how to calculate final impedance of the system?

or the other way round, how do I form a crossover if I am using yamaha RX V361 , which likes 6 or 8 ohm speakers.

from the net i got values of capacitor and inductors and R Pad but then I am stuck.

friends, please help me.

Please look at the following link where someone has done a threeway speaker, all drivers are 8 ohms and he has given crossover design. Now please tell me what will be final impedance presented to the amp?
