Baffle Step Correction Circuit Calculator
A Baffle Step Correction Circuit (BSC), can be used to solve the baffle step response problem of loudspeakers in free space. A schematic of the Baffle Step Correction Circuit is shown below. The Baffle Step Correction Circuit is placed between the amplifier and the speaker. For information and theory about the baffle step response phenomenon, see Martin J. King's article Simple Sizing of the Components in a Baffle Step Correction Circuit.
Where:
- Re is the DC resistance of the driver voice coil [ohms],
- Wb is the width of the baffle [inches],
- dB is the amount of attenuation required [decibels],
- f3 is the frequency midpoint of the transition from 4π space to 2π space,
- Lbsc is the calculated baffle step correction circuit Inductor [mH] and
- Rbsc is the calculated baffle step correction circuit Resistor [ohms].
You can use this online calculator to determine the value of the required baffle step correction circuit Inductor (Lbsc) and Resistor (Rbsc). To use the online calculator, simply enter Re, Wb and dB (the amount of attenuation required) into the boxes below and click the CALCULATE button. Use the CLEAR button to reset all the values.
