3.3 Instructions�for�Speaker�Stacking
Warning
Falling�speakers�pose�the�threat�of�fatal�injuries�to�people�near�them!
Be sure to follow the relevant national specifications, norms, and safety regulations.
Always make sure that a sufficient safety level is still given, even when outside forces have an addi-
tional impact on the stacked speakers. Before setup, carefully ascertain if there are any possible out-
side forces that could result in the array falling over. (Slant of the ground / the bearing capacity of the
ground / wind / person or vehicle impact, etc.). A technical expert who is responsible for the setup
must evaluate and determine necessary measures (including calculating the statics). If necessary, ob-
tain expert proof of stability.
Stacked systems may not fall over even if they are inclined by 10° in each direction. If this require-
ment is not fulfilled, then it is necessary to take steps to achieve compliance. Possible measures in-
clude strapping it to an appropriate base structure or fastening it using safety straps. A planned tilt of
the loudspeakers ist not permissible. In calculations, the tilted setup serves the purpose of levelling out
unevenness.
With the set-up systems for which you cannot verify the structural safety without safeguards, you
must secure them to prevent sliding or tipping in order to provide proof of this safety. To secure the
system from tipping over, use water tanks or floor bolts. Other possible measures include strapping it
to a suitable substructure or tying it using safety straps.
For outdoor and trade fair venues in which wind loads must be considered, additional proof of stabili-
ty is necessary.
Make sure that the stacking feet of subwoofers stacked on top of one another are securely positioned
in the grooves of the lower speaker.
If you place a top speaker on a NOMOS LS you must always strap the speakers to one another and
secure them from falling over.
3.4 Preventing�hearing�damage
Caution
Avoid beeing too close to operating speakers. This equipment is capable of delivering sound pressure
levels in excess of 90 dB/SPL, which may cause permanent hearing damage.
