How to use

Place the SUB 618 on a stable surface or mount in the recommended orientation for the best bass dispersion. Connect the line-level outputs of your mixer or audio processor to the subwoofer’s input using balanced cables. Set crossover and level to complement main speakers — typically using a crossover point appropriate for main speaker low-frequency limits. Power on the unit and adjust gain to achieve the required bass level without clipping. For touring or rental use, secure the enclosure during transport and handle the driver area carefully to avoid impact damage.

Recommendations

For optimal performance, use the SUB 618 with full-range loudspeakers and set the crossover near the low-frequency cutoff of the main speakers. Allow the built-in amplifier sufficient ventilation during extended use and avoid placing heavy objects on the enclosure. Regularly inspect connectors and mounting hardware when used in touring or permanent installations.
