3.1 Instructions for Speaker Placement
3.2 Instructions for Speaker Stacking
Mount the speakers securely. To avoid injury or damage, always be sure to mount the speakers
securely so that they do not fall.
Note that the speakers can move as a result of vibrations. To prevent them from falling from
their mounted position, they must be secured properly.
When laying the connecting cables, make sure that nobody can trip.
Tipping speakers impose a deadly risk for people standing near-by!
Be sure to follow the relevant national specifications, norms, and safety regulations.
Always make sure that the speakers are sufficiently secured, so they cannot fall over even when
external forces affect the speaker stack. Before installation, carefully check whether there are
any external factors that may cause the stack to fall over. These include, for example, the
ground slope or bearing capacity, winds, and impacts of persons or vehicles. Qualified and ap-
propriately trained installation personnel are in charge of evaluating the scenario and perform-
ing all required steps (including statics analysis). Proof of stability must be obtained if and as
necessary.
Stacked systems must not fall over even if they are inclined by 15° in any direction. If this re-
quirement is not fulfilled, be sure to take appropriate steps. E.g. lashing the
speakers onto a suitable base or fastening them using straps. Never allow intended speaker
tilting. The corresponding feature is simply used to account for unevenness during stability
evaluation.
Where the stability of installed systems cannot be proven without additional safety measures,
those systems must be effectively secured against sliding and tipping to achieve compliance.
For example, secure the system against tipping using water tanks or floor bolts. Other possible
measures include lashing the speakers onto a suitable base or fastening them using straps.
With applications where winds may occur, for example, outdoor events, tradeshows, etc., be
sure to perform extra stability checks.
Make sure that the feet of stacked subwoofers engage with the corresponding hollows of the
lower speaker.
If you place a top speaker on a NOMOS XLT you must always strap the speakers to one another
and secure them from falling over.
