OWNER’S GUIDE
SPEAKER PLACEMENT
Low-frequency sounds are
normally omnidirectional,
It is generally recommended
that the speaker be installed so
that the bottom of the speaker
is approximately 12" from the
floor. This is to help with the
low-frequency loading (bass
reinforcement). This also helps
hide the speaker in a less visi-
ble place. In special circum-
stances it is acceptable to
install the speaker at any
When using two SS88IWS in-
wall subwoofers, you may need
to be concerned about phase,
as the sound waves may
cancel each other out. If bass
response seems low, try invert-
ing the polarity on one sub-
woofer – i.e., connect the (+)
terminal on the amplifier to the
(–) terminal on the speaker, and
the (–) terminal on the amplifier
to the (+) terminal on the
meaning the listener can’t tell
where they are generated from.
However, frequencies between
75Hz and 150Hz can be local-
ized, especially at higher vol-
ume levels. Positioning your
subwoofer as recommended
will provide the most natural
soundstage and imaging from
your loudspeaker system.
height on a wall.
speaker.
It is generally recommended
that you install your SS88IWS
in-wall subwoofer along the
same wall as the front loud-
speakers. The SS88IWS sub-
woofer is not video-shielded
and should not be placed near
a video display. Installing the
SS88IWS near a corner will
tend to maximize low-frequency
output. Be cautious when
installing in a corner, to avoid a
“boomy” sound. Also take into
consideration any unusual fea-
tures of the room, such as an
alcove, which may tend to cre-
ate a localized node that may
affect bass response in that
area of the room.
Remember that these are just
guidelines. Since every listen-
ing room is different, JBL
strongly recommends experi-
menting with the positioning of
your subwoofer prior to cutting
the wall to obtain the most
pleasing results in your room.
One technique that can help
you find the ideal subwoofer
location is to temporarily bor-
row a stand-alone subwoofer
and place it near the main lis-
tening location. Then move
around the room and determine
where you hear the most pleas-
ing bass performance. This
would then be the ideal loca-
tion for the subwoofer.

However, you must remove the
shorting straps when using

may connect each channel to

Notes:
Level
• Use the cardboard template
when cutting the drywall.
Although the SS88IWS may
be oriented either horizontally
or vertically, the installation
procedure is the same.
Template
• Please be aware the tem-
plate is slightly oversized to
allow for some margin of
error when cutting with the
drywall saw – there should
be no need to allow for fur-
ther margin of error as this
may risk the integrity of the
installation.
The grille is packed separately
from the speaker. If at some
later date you wish to remove
the grille from the speaker, to
avoid scratching the grille or
baffle you may unfold a paper
clip, insert the straight end
through one of the holes in the
grille, and gently pull up.
Determine the correct speaker
location.

Cut the drywall.
Connect the speaker wires
to the speaker as
described on pages 4–7.
Note: Always allow at least
one-half inch between a wall
stud and the speaker cutout, or
the locking tabs will not be able
to swivel into place.
Place the frame assembly in
the wall until the frame surface
is flush with the wallboard.
Screw down each of the ten
Phillips-head screws. It is best
to use a low-speed cordless
driver or a hand-held screw-
driver to tighten the screws to
prevent over-tightening. The
locking tabs will swivel into
place and secure the unit to the
rear surface of the drywall.
Replace the metal grille. Attach
the JBL logo to the grille to cor-
respond to vertical or horizontal
installation.

wall. The bottom edge of the
bottom L-brackets will rest
against the baseboard two-

note of adjustments neces-
sary to square the enclosure
into the wall (see Detail C).

Centering Bar
Installation:
1. Install the two centering bars
as shown in Detail B in the
drawings. The centering bars
are for setting the depth of
the enclosure. They also help
locate the left/right position
of the enclosure as they can
be mounted into the studs at
the left and right to hold the
enclosure in the correct loca-
tion before final mounting.

4. After refitting and tightening
the L-brackets into the enclo-
sure (but not the wall studs
yet), fit the enclosure into the
wall once again.
2. Install the four L-brackets to
the four corners of the en-
closure. 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 to the
wall studs at this time (see
step 6).
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.
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).
See
Detail A
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
SS88IWSBB connections
panel, and to any other
speakers as appropriate for
your system, following the
instructions on pages 4–7.
Connect the eight wires
hanging from the bottom of
the SS88IWSBB back box to
the correct terminals on the
SS88IWS loudspeaker. See
pages 6–7.
PAINTING THE SPEAKER
FRAME AND GRILLE
JBL in-wall loudspeakers can be
painted to match any décor. If
you wish to change their color,
the satin finish on the grille and
frame will function as a primer
coat. Before painting, install the
plastic paint shield securely into
the recess in the baffle. This will
protect the speaker components
and baffle from paint residue.
Use a high-quality spray paint,
and apply a thin coat of color.
Paint the grille separately from
the baffle before installing it.
Be certain the grille
perforations remain
free of paint. Filling
them with paint will
diminish the sound
quality.
