4. INSTALLATION
The special hexagonal shape of the cabinet makes it possible to
position the speaker in various way, as shown in the gure. The
EAW Commercial 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.
The SMS4 (SMS4W) loudspeakers 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.
