4. INSTALLATION
The special hexagonal shape of the cabinet makes it possible to
position the speaker in various ways, as shown in the gure. The
logo plate on the front protective grille can be rotated to adapt
it to the position of the speaker. The speaker body has four M6
threaded inserts, one each on the top and bottom and two on the
back, used for attaching accessories for installing the speaker in
different ways.
SMS3 (SMS3W) speakers are supplied with a black (white)
ball joint support for wall mounting.
WARNING: Consult a professional rigger or structural
engineer prior to suspending loudspeakers from a
structure not intended for that use. Always know the
working load limit of the structure supporting
the loudspeaker array. Always make sure
that the rigging hardware minimum rating is
at least ve times the actual load.
