INSTALLATION
Although the JBL Performance
S
pecialist Series in-wall speakers
were designed to be easily
installed in existing construction
a
pplications, it is recommended
that installation of the SS88IWSBB
back box in new construction
b
e reserved for professionals.
See the manual for the SS88IWS
s
ubwoofer for instructions on
i
nstalling the speaker in existing
construction without using the
back box.
T
he SS88IWSBB back box is an
o
ptional installation accessory for
the SS88IWS in-wall subwoofer.
When used, the SS88IWSBB back
box is installed during new con-
struction before the wallboard.
Installation
1. Using the four flat-head screws,
install the two centering bars as
shown in Detail B in the draw-
ings. The centering bars are for
setting the depth of the enclo-
sure. They also help locate the
left/right position of the enclo-
sure as they can be mounted
into the studs on the left and
right to hold the enclosure in the
correct location before final
mounting.
2.
Using the eight #10 32 x 1" screws,
install the four L-brackets
at the
four corners of the enclosure.
Each of the eight screws should
have both the split washer and
flat washer installed; the split
washer goes on first. Leave the
screws a half-turn loose at first
to allow for adjustment later
(see Detail A). Do not screw the
L-brackets into the wall studs at
this time (see step 6).
3. Fit the enclosure into the wall.
The bottom edge of the bottom
L-brackets will rest against the
baseboard two-by-four. At this
time, make note of adjustments
necessary to square the enclo-
sure into the wall (see Detail C).
4. After refitting and tightening the
L-brackets into the enclosure
(but not the wall studs yet), fit
the enclosure into the wall once
again.
5.
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 help hold the enclosure in
position before the L-brackets
are mounted to the studs.
6. Screw the L-brackets into the
studs, using the eight wood
s
crews.
7
. Remove the wood centering
bars and replace the flat-head
screws into the holes left over
(the holes left in the cabinet
face underneath the bars are
also counterbored to accept the
flat-head screws).
8. The enclosure is now installed
and ready for the wallboard to
be installed over it.
9. Make the connections from
your receiver/amplifier to the
SS88IWS back box connections
panel, and to any other speak-
ers as appropriate for your sys-
tem, following the instructions
on the previous page. Connect
the eight wires hanging from the
bottom of the SS88IWSBB back
box to the correct terminals on
the SS88IWS loudspeaker (see
the previous page).
