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 features of the room, such
as an alcove, which may tend to
create a localized node that may
affect bass response in that area
of the room.
THANK YOU FOR
CHOOSING JBL PLACEMENT
SPEAKER
For more than 60 years, JBL has
been involved in every aspect of
music and film recording and
reproduction, from live perform-
ances to monitoring the recordings
you play in your home, car or
office.
It is best to establish the locations
for the speakers in advance, to
avoid having to correct errors
after installation has already
begun. Refer to these guidelines,
and also see the owner’s guide for
the SS88IWS subwoofer for more
information.
We’re confident that the JBL
speaker and back box you have
chosen will provide every note of
enjoyment that you expect – and
that when you think about pur-
chasing additional audio equip-
ment for your home, car or office,
you will once again choose JBL.
Please take a moment to register
your product on our Web site at
you posted on our latest advance-
ments, and helps us to better
understand our customers and
build products that meet their
needs and expectations.
It is generally recommended that
the speaker be installed so that the
bottom of the speaker is approxi-
mately 12" from the floor. Note that
installing the speaker within the
SS88IWSBB back box as shown in
the illustration to the left will
achieve the recommended height.
This is to help with the low-fre-
quency loading (bass reinforce-
ment). This also helps hide the
speaker in a less visible place.
It is generally recommended that
you install your SS88IWS in-wall
subwoofer along the same wall
as the front loudspeakers. The
SS88IWS subwoofer is not video-
shielded and should not be placed
Remember that these are just
guidelines. Since every listening
room is different, JBL strongly rec-
ommends experimenting 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 borrow a stand-
alone subwoofer and place it near
the main listening location. Then
move around the room and deter-
mine where you hear the most
pleasing bass performance. This
would then be the ideal location
for the subwoofer.

INSTALLATION
Although the JBL Performance
Specialist Series in-wall speakers
were designed to be easily
installed in existing construction
applications, it is recommended
that installation of the SS88IWSBB
back box in new construction
be reserved for professionals.
See the manual for the SS88IWS
subwoofer for instructions on
installing the speaker in existing
construction without using the
back box.
See
Detail A
Detail C
L-Brackets
See
Detail B
6. Screw the L-brackets into the
studs, using the eight wood
screws.
Centering Bar
The SS88IWSBB back box is an
optional installation accessory for
the SS88IWS in-wall subwoofer.
When used, the SS88IWSBB back
box is installed during new con-
struction before the wallboard.
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).
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.
8. The enclosure is now installed
and ready for the wallboard to
be installed over it.
Centering Bar
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).

Detail C
L-Brackets
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).
Detail A
See
Detail A
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).
Detail B
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.
