Stand-Mounting
- Always install subwoofers in accordance with applicable electrical and building codes.
- Install the subwoofer according to its maximum weight. Check the specifications of your stand
or pole to ensure it can support the loudspeakers we ight. Also, observe all safety precautions
specified by th e manufacturer.
- Do not mount multiple loudspeakers on the same stand or pole.
- Always verify that the stand or pole is on a flat, level, and stable surface.
- Inspect the stand (or pole and associated hardware) before each use and do not use equipment
with worn, damaged, or missing parts.
- Always be cautious in windy, outdoor conditions. You may need to place additional weight (e.g.,
sandbags) on stands base to improve stability. Do not attach banners or similar items to any
part of a loudspeaker system. Such attachments could act as a sail and topple the system.
- Unless you are confident that you can handle th e loudspeakers weight, ask another person to
help you lift it onto the stand or pole.
- Make sure your cables are out of the way of performers, production crew, and audience so they
will not trip over them, pulling the loudspeaker off the stand or pole.
