- Njikwa olu: Start with the "LEVEL" knob on the subwoofer set to its minimum position. Gradually increase the level to achieve the desired bass output.
- Ugboro crossover: The S12A features a switchable high-pass filter. Select between 100 Hz or 160 Hz depending on your system's requirements and the frequency response of your full-range speakers.

- 160 Hz: May be used with smaller full-range speakers that require more low-frequency support.

Listen to the system with both settings and choose the one that provides the most coherent and impactful bass response. Often, the correct phase results in a fuller, more defined low end.
