Electronic divider filter calculator

The electronic crossover filter calculator is a special calculator for crossover design. The crossover filter calculator can quickly and accurately calculate the specific value of the crossover of the speaker system (speaker).

Enter the desired crossover frequency: Fol = Foh = Hz,
The calculated value is directly matched with the above configuration
R = C = µF
R2 = C2 = µF
R4 = C4 = µF
R7 = C7 = µF

Way of calculation:
Theoretical value of R ...
(Frequency Fc < 200 Hz Choose to use R = 100 KΩ,otherwise R = 10 KΩ):
C = (10/R)*50
2 π F
     C2 = 2455.3
2 π F R
     C4 = 2108.9
2 π F R
     C7 = 193.1
2 π F R
 
R2 = 407.4
2 π F C
  R4 = 474.2
2 π F C
  R7 = 5176.6
