Wall mounting applications

SI 28

Surface Mount Speakers

NBefore starting installation ensure the wall and wall material is capable of supporting the combined weight of the speakers and the wall mount assemblies.

To install the wall assembly mount, follow the installation steps given in "Installing the wall mount assembly", steps 1 through 9, in your "SI 26 and SI 28 User's Manual".

Mounting the SI 28 speaker on the Wall Mount Assembly

To prepare the speaker for mounting, refer to "Mounting the speaker onto the wall mount assembly", steps 1 and 2 in your "SI 26 and SI 28 User's Manual", then follow steps 3a through 3c and 4 below.

3a. Carefully lift the speaker up as close to the bottom of the wall mount assembly as possible and hook the right outer edge of the speaker box bracket over the right inner edge of the V-lock groove (see figure 1).

NHolding the speaker so that the lowest part of the speaker is as close to the bottom of the V-lock groove as possible, makes it easier to hook the two parts together.
