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.

Warning

When laying the connecting cables, make sure that nobody can trip.

3.2

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

Warning

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 appropriately trained installation personnel are

in charge of evaluating the scenario and performing 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 requirement is

not fulfilled, be sure to take appropriate steps. E.g. lashing the

Where the stability of installed systems cannot be proven without additional safety measures, those sys-

tems 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 per-

form extra stability checks.

Make sure that the feet of stacked subwoofers engage with the corresponding hollows of the lower

speaker.
