JBL Synthesis S4S - Manual (Page 7)

Installation:
1. Place the Styrofoam ™ blocks on the bottom plate of
the stud bay. The S4SBB back box will rest on top of
the blocks.
2. Install the two centering bars as shown in Detail A on
page 6. The centering bars are for setting the depth of
the enclosure. They also help locate the horizontal
position of the enclosure as they are mounted into
the studs at the left and right to hold the enclosure in
the correct location.
3. Fit the enclosure into the wall. The bottom of the
S4SBB back box will rest on top of the Styrofoam
blocks 5 that you put on the baseboard two-by-four
in Step 1.
4. At this time, you may want to screw through each side
of the wood centering bars to mount the enclosure to
the studs. This will hold the enclosure in position.
5. Install each of the ten bushings into their mounting
holes 1. Insert one end of the rubber bushing into the
hole, then place a flat washer on top of the bushing
and screw the supplied 5" deck screw through the
washer and into the bushing.
6. The enclosure is now installed and ready for the
wallboard to be installed over it. Remove the wood
centering bars and use the wood screws to close up
the holes in the S4SBB back box. The drywall cutout
dimensions are 24.55" (H) x 15" (W) (624mm x 381mm).
7. Insert the six plastic grille spacers into the large holes
in the S4S baffle. Select either the small or large grille
spacers, depending on whether your application
requires one or two layers of wallboard. The grille
spacers are inserted from the back side of the S4S
baffle. Then insert the grille cups into the grille
spacers from the front of the S4S baffle.
8. Make the connections from your receiver/amplifier to the
S4SBB back box connections panel, and to any other
speakers as appropriate for your system, following the
instructions on pages 4–5. Connect the wires hanging
in the opening of the S4SBB back box to the correct
terminals on the S4S loudspeaker (see pages 4–5).
9. Install the S4S baffle into the S4SBB back box using
the twelve screws, as shown in the illustration at right.
10.The grille pegs mount in the grille cups to complete the
installation.
