SPEAKER
PLACEMENT
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.
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

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.
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.
Remember that these are just
guidelines. Since every listening
room is different, JBL strongly rec-
ommends experimenting with the
positioning of your subwoofer prior
DAMPING
to cutting the wall to obtain the
PADS
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
