Proper placement of the 
speakers is an important step 
in obtaining the most realistic
soundstage possible. These
recommendations are for the
optimum placement of the loud-
speakers. Use these placement
recommendations as a guide.
Slight variations will not dimin-
ish your listening pleasure.

The front speakers should be
placed the same distance from
each other as they are from the
listening position. They should

be placed at about the same
height from the floor as the 
listeners’ ears will be, with the
tweeters aimed toward the 
listening position at ear-level
height.

Model HTI55 is suitable for the
front left, center and right posi-
tions, and it may also be used
as a side surround or surround
back speaker. It may be
mounted horizontally or verti-
cally, but make sure to position
it so that the tweeters for all of
the front speakers are at the
same height (or differ by no
more than 2 feet). You may
rotate the tweeter to correctly
orient the JBL logo.

In a home theater configura-
tion, the two surround speakers
should be placed slightly
behind the listening position

and, ideally, should face each
other and be at a level higher
than the listeners’ ears. If that
is not possible, they may be
placed in a wall behind the lis-
tening position, facing forward.
The rear wall is the required
mounting position for the sur-
round back speakers in 6.1- and
7.1-channel system. The sur-
round speakers should not call
attention to themselves. They
should provide a diffuse, ambi-
ent sound accompanying the
main program material heard in
the front speakers. In Dolby*
Digital and DTS

®

systems, aim

the tweeters toward the listen-
ing position at ear-level height.

The JBL HTI Series in-wall
speakers were designed to be
easily installed. However, if you
are unsure of your ability to
properly install these loud-
speakers, please contact your
dealer or a qualified installer.

Speakers and electronics
terminals have corresponding
(+) and (–) terminals. 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
systems, connecting all of 
the speakers in your system
with the correct polarity
remains equally important in
order to preserve the proper
ambience and directionality 
of the program material.

The wires for both speakers
should be the same length. If
one speaker is placed closer to
the amplifier than the other,
hide the excess wire behind the
wall.

Remove the grille from the
speaker frame by pulling on the
paper tab. If the tab is missing,
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. 

Note: Remove the inner tem-
plate, which is the paint shield,
at the perforation. Use the
outer template when cutting
the drywall. Although the HTI55
may be oriented either horizon-
tally or vertically, the installa-
tion procedure is the same.

Connect the speaker wires to

Replace the metal grille. For the
HTI55 only, attach the JBL logo
to the grille to correspond to
vertical or horizontal installa-
tion.

Place the frame assembly in
the wall.

Screw down each of the four
(six for HTI55) Phillips head
screws. The locking tabs will
swivel into place and secure
the unit to the rear surface of
the drywall.

The HTI speakers feature
unique swivel mounts for the
tweeters that enable you to aim
the very directional high fre-
quencies toward the 
listening position, at ear-level
height. Before installing the
speaker grille, gently press on
the outer edge of the tweeter
mount to adjust the position of
the tweeter. The tweeter will
not swivel more than 15
degrees in any direction; do not
attempt to force it to move fur-
ther. You may also rotate the
tweeter to orient the JBL logo
as desired.
