1 Important safeguards
!
Caution!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of rigging objects
overhead. Bosch strongly recommends that loudspeakers be suspended taking into account
all current national, federal, state and local regulations. It is the responsibility of the installer
to ensure that loudspeakers are safely installed in accordance with all such regulations. If
loudspeakers are suspended, Bosch
strongly recommends that the installation is inspected at least once a year. If any sign of
weakness, damage or corrosion is detected, remedial action should be taken immediately. Do
not use mounting material and supporting structures of stainless steel in a chlorine-rich
environment such as indoor swimming pools. Bosch strongly
recommends to use mounting material of thermogalvanized steel for this kind of
environments. All non-Bosch associated hardware items used to suspend the Bosch
loudspeaker are the responsibility of others.
!
Caution!
In case the 8 Ohm connection of loudspeaker is used, be sure that the 8 Ohm output of the
connected amplifier is DC free. If this is not the case, connecting a suitable bipolar condenser
(47 μF -100 μF) in series with the loudspeaker is recommended.
!
Caution!
Make sure that you use the safety eye and the main M8 rigging point when you install the
loudspeaker
Notice!
The mounting materials marked with an asterisk (*) in the drawings are not supplied, but are
generally available in your local DIY-store. Make sure that the minimum tensile strength of
these mounting materials (e.g. suspension chain, suspension cable, safety cord and
shackle[s]) is 1,500 N.

7 Listening area and related mounting height
How to define a listening area?
1. Define the height between the loudspeaker and the floor.
2. What is the desired maximum SPL variation from center to the edge of the listening area?
3. Look, in the table below, in the column for the specified height and in the row for the
specified maximum SPL variation.
4. At the intersection of the row and column the diameter and the surface is given of the
listening area.
The color indicates the range of minimum dB SPL for the listening area at maximum power:
