15. Ground stacked systems
Loudspeakers that need to be portable or re-configured on a regular basis for a venue like a
performing arts center or multi-purpose facility can be ground stacked for convenience.
All ground stacked speakers, especially in locations where public may gain access to the
systems (e.g. stages in music venues), even if unauthorized, should have the system
permanently anchored down (e.g. by load straps).
Always check the supporting surface (e.g. floor, stage etc) that the speaker system is to be
placed upon, to ensure that the floor is even and level. If necessary, survey the underside of
any temporary structure such as staging to ensure that it sufficiently stable and supported.
Sloping stage surfaces (e.g. in theatres), may require blocks to make the surface level. If it is
not, have a carpenter provide a suitable platform.
.
Rubber blocks or mats may be placed between cabinets as necessary to prevent upper cabinets
from “walking” – i.e. movement due to the speaker’s vibration.
Follow proper manual handling procedures when stacking and unstacking systems to reduce
risk of injury, and always ensure sufficient personnel and equipment are available.
The Installation Series products are designed for indoor use only.
