L pad calculator - attenuation dB damping impedance decibel loudspeaker speaker voltage divider (original) (raw)
For attenuation A (damping) take a positive dB value, used as convention.
For attenuation A take a negative dB value, used as convention.
Calculate the L pad resistor network
The calculator below requires a positive value for A in dB.
