C - Capacitor
L - Inductor

Inputs:

 Impedance of tweeter (RH) ohms Impedance of woofer (RL) ohms frequency (f) hertz

Given:

 RH = 0 RL = 0 f = 0

Solution:

 C1 = HAS NOT BEEN CALCULATED C2 = HAS NOT BEEN CALCULATED C3 = HAS NOT BEEN CALCULATED C4 = HAS NOT BEEN CALCULATED L1 = HAS NOT BEEN CALCULATED L2 = HAS NOT BEEN CALCULATED L3 = HAS NOT BEEN CALCULATED L4 = HAS NOT BEEN CALCULATED
Bessel:
 C1 = HAS NOT BEEN CALCULATED C2 = HAS NOT BEEN CALCULATED C3 = HAS NOT BEEN CALCULATED C4 = HAS NOT BEEN CALCULATED L1 = HAS NOT BEEN CALCULATED L2 = HAS NOT BEEN CALCULATED L3 = HAS NOT BEEN CALCULATED L4 = HAS NOT BEEN CALCULATED
Butterworth:
 C1 = HAS NOT BEEN CALCULATED C2 = HAS NOT BEEN CALCULATED C3 = HAS NOT BEEN CALCULATED C4 = HAS NOT BEEN CALCULATED L1 = HAS NOT BEEN CALCULATED L2 = HAS NOT BEEN CALCULATED L3 = HAS NOT BEEN CALCULATED L4 = HAS NOT BEEN CALCULATED
Legendre:
