4. INSTALLATION

The special hexagonal shape of the cabinet makes it possible to position the speaker in various way, as shown in the figure. 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 five times the actual load.
