SPEAKER PLACEMENT
Low-frequency sounds are
normally omnidirectional,
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.

It is generally recommended
that you install your HTI88 in-
wall subwoofer along the same
wall as the front loudspeakers.
The HTI88 subwoofer is not
video-shielded and should not
be placed near a video display.
Installing the HTI88 near a cor-
ner 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 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
height on a wall.

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 location
for the subwoofer.

When using two HTI88 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 in-
verting 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
speaker.

ENGLISH
Speakers and electronics have
corresponding (+) and (–) termi-
nals. Most manufacturers of
speakers and electronics,
including JBL, use red to
denote the (+) terminal and
black for the (–) terminal. It is
important to connect both
speakers identically: (+) on the
speaker to (+) on the amplifier
and (–) on the speaker to (–) on
the amplifier. Wiring “out of
phase” results in thin sound,
weak bass and a poor stereo
image. With the advent of multi-
channel surround sound

If two HTI88 subwoofers are
used, the wires for both speak-
ers should be the same length.
If one speaker is placed closer
to the amplifier than the other,
hide the excess wire behind the
wall. If bass response seems
low, there may be a phase
problem, with the sound waves
from the two subwoofers can-
celing 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

speaker, press the colored tab
and insert the bare end of the
wire into the hole. Release the
tab and gently tug the wire to

To use the push-type terminals
on the connections panel sup-
plied with the optional HTI88BB
“back box” enclosure, depress
the colored cap until the pass-
through hole in the binding post
is revealed. While holding the
cap down, insert the bare end
of the wire, or a banana plug,
into the pass-through hole.
Release the cap and tug gently
on the wire to ensure that it is
secure.
