Circuit usage:
- for impedance linearisation, where R is usually higher than 4 Ohm. The circuit could be adapted to the driver's resonance in the corresponding cabinet.
- to suppress the resonance of metal cone drivers; therefore, the circuit should be set considerably higher than the crossover frequency; should be mounted in parallel to the driver.

- you either enter the minimum impedance in the yellow fields, indicate at which frequency this should be and then press the calculation button "RLC?". With the buttons to the left and right the resonance may be narrowed or widened.
- or you enter the components' values in the yellow field (above left) and press the button "Calculate Impedance".
