Loudspeaker Mounting
•
Always install subwoofers in accordance with applicable electrical and building codes.
•
When using a pole in the pole cup on top of the subwoofer cabinet to mount a loudspeaker, ensure the
pole is rated to support the loudspeaker's weight. Also, observe all safety precautions specified by the
manufacturer.
•
Do not mount multiple loudspeakers on the same pole.
•
Always verify that the subwoofer is on a flat, level, and stable surface that can support the weight of the
subwoofer and any mounted loudspeaker and mounting equipment.
•
Inspect the subwoofer, 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. 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 the subwoofer's weight, ask another person to help you
with any setup needs related to the subwoofer and any mounted speakers and related accessories.
•
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.
(Optional) Attaching Casters
In order improve the experience of transporting our subwoofers, the TS15S and TS18S come with inserts
