Pole or stand mounting 

Performer full-range loudspeakers incorporate pole mounting (“top hat”) sockets so that they may be pole or stand mounted.

When using poles or stands, the following precautions are advised:

▪ Ensure that the stand will support the weight of the speaker by checking the stand manufacturers rating.

▪ Make sure that the stand is placed on a level surface and that its legs are fully extended.

▪ Do not place more than one speaker on each stand.

▪ Run cables so that they do not present a trip hazard which could pull the speaker over.

▪ When used outdoors in the wind, it may be necessary to add some weight to the base of the stand.

▪ When using a pole mount with a sub-bass system, observe similar precautions.


▪ Ensure that the floor or stage is level and solid.

▪ Do not stack speakers too high outdoors where winds could topple the stack.

▪ Be aware that speakers producing very high power levels can move or creep. To avoid this, place friction material between the floor and speaker and between each speaker or use strapping to secure the stack.
