3. Setup
Unpacking and Initial Inspection
Carefully remove the subwoofer from its packaging. Verify that all components are present. The package should contain the ELX200-12SP subwoofer unit and a power cable. Inspect the unit for any signs of damage that may have occurred during shipping. If any damage is found, contact your dealer immediately.
Placement
For optimal low-frequency performance, consider placing the subwoofer on a solid, flat surface. Corner placement can enhance bass response. Ensure adequate ventilation around the unit to prevent overheating. The integrated M20 threaded pole mount plate allows for mounting a full-range speaker on top of the subwoofer using a compatible speaker pole (sold separately).
