surface, the speaker must be recessed in the wall no more than 1/4 inch. The grille pins fit directly into the speaker cabinet via receiver bushings with 15 ft/lb of tension per pin. Use the marked speaker-depth-indicator flanges (attached to the sides of the speaker baffle) to appropriately adjust the depth from the wall surface so that the baffle is recessed 1/4 inch. This will ensure that the grille will sit flush to the wall surface.

REQUIREMENTS FOR MOUNTING

OPTION 1 – NEW CONSTRUCTION: The S4PCB mounting-flange bracket must be installed before the drywall is installed in the room. Attach the included L-brackets to the speakers (see Figure 14), and attach them to the mounting flanges at the appropriate recessed distance. The S4VC and S4HC require a minimum 6" wall depth. The S4Ai requires a minimum 4" wall depth (see Figures 15, 16 and 17).
