The calculation
For each branch at resistance R: L = R / (πfc); C = 1 / (4πfcR) Low-pass: series L, shunt C High-pass: series C, shunt L L in H; C in F
Assumptions & limits
Assumes resistive loads, ideal components and zero source impedance. Electrical slopes do not include the drivers’ acoustic responses. Measure the complete loudspeaker before choosing final parts.
