INTRODUCTION
Congratulations on choosing JBL
HT Series loudspeakers. Their
highly accurate, uncolored and
balanced sound character will
greatly increase your enjoyment of
the Home Theater experience. We
at JBL build with careful attention
to detail, using only the highest
quality materials. They will give
you many years of excellent
performance.
The HT Series rivals the
performance of more expensive
loudspeakers. It meets Home
THX
®
Audio System Performance
Standards.
THX
®
-Licensed Home Audio
System:  When used with a Home
THX
®
controller and amplifiers,
your complete 7-piece JBL HT
Series speaker system, will deliver
state-of-the-art THX
®
home theater
experience to your home. The HT
Series also delivers accurate
stereo music reproduction when
listening to CD's, tapes, or other
program information.
Pure Titanium Tweeter with
Diamond Surround: 
provides a
well-defined high frequency output
with low distortion, flat and smooth
high frequency response, and no
break-up in the audio range. 
High Polymer Laminate Mid-
bass Drivers and Woofers:
combine to provide tight bass and
well-defined, smooth midrange,
without harshness, stridency, or
listener fatigue. 
High Quality Crossover
Network: 
Our computer-optimized
dividing network employs up to
third-order (18 dB per octave)
crossover sections. JBL uses
audiophile-grade polypropylene
capacitors and low-loss/low-
distortion inductors to prevent
phase or amplitude distortions. 
Acoustically Optimized Cabinet
and Grille Design: 
provide
smooth uncolored sound and
eliminate diffraction and unwanted
resonances.  
Magnetic Shielding: allows you
to place your front channel and
subwoofer speakers near video
monitors without creating
interference or distorting the
picture.
The Center channel front speaker
should be positioned vertically
and centered either above or
below the middle of the screen (or
behind the screen if you have a
projection T.V. with a perforated
screen). All three front speakers
should be mounted "flush" to the
screen and in the same plane
relative to the screen.
The Left and Right should be at
the exact same height, and the
Center should be no more than 2
feet higher or lower. Your Center
channel speaker must be vertically
oriented. Turning it on its side will
prevent your HT1 system from
producing the correct sound field.
SUBWOOFERS
The Subwoofers can be placed
on either side of the screen or in
the corners of the room. A good
configuration for a mono
amplifier/dual HT1S setup that
lessens the effect of room modes
is one subwoofer in a corner, the
other in the middle of a wall.
PLACEMENT
Placing your speaker components
properly is vital to achieving the
correct sonic performance. Please
read the following sections
carefully for proper placement.
They are  divided into front
channel speakers (HT1F: Left-
Center-Right), subwoofers
(HT1S), and dipolar surround
speakers (HT1D).
FRONTS (Left-Center-Right)
The Left and Right front channel
speakers should be located on
either side of the T.V. screen or
projector. Closer to the screen
gives you more localization while
farther (two to three feet from the
screen on each side) will give you
a wider sound field. Ideally, you
want to try to put the speakers
about 45 degrees apart from each
other, viewed from the listening
position. The center line of the
speaker (the area between the two
tweeters) should be at the same
height as actors on the screen
would be. Depending on the
height of your T.V. screen, you
may be able to place the Left and
Right speakers directly on top of
your subwoofer cabinets. If your
screen height doesn't allow this,
you may place the Left and Right
speakers on a speaker stand to
achieve the proper height.
Depending upon your
configuration, you may also need
a stand for the center speaker that
tilts it so that it points towards the
listener's ear level. Your JBL
dealer can help you purchase a
stand that meets your height
requirement.

SURROUNDS 
Place the Surrounds to the sides, or
slightly behind the viewing position
with the rear panel of the speaker
(where the speaker wire connections
are) up against the wall. 
Do not
position the Surround speakers so
that the drivers (under the grille area)
point directly at the listener. Remove
both grilles from each Surround and
note the location of the oval port tube
hole on the baffle. Align the driver side
with the oval port tube so it faces the
direction of the screen. This will mean
one surround is "right-side-up" and the
other "upside-down" in relation to each
other. This will not affect the sound
quality. You may replace the grilles so
that the orientation of the JBL Logo is
correct. Correct height placement for
the Surrounds is between 2 and 3
feet above seated ear level.  Mount
your Surrounds on speaker stands or
place them on shelves attached to 
the wall.
If your home theater room is of a
configuration that does not lend itself
to the above placement suggestions,
then it becomes more important to
consider the “null” direction of the
Surround. The null baffle is the blank
panel between the two rounded edges
of the cabinet. It is most important to
point this panel at the listening
position. Creativity and careful
listening will tell you where the ideal
position is for the placement of the
Surround speakers. For example, if
your listening position is up against
the rear wall of the room, placing the
Surrounds about 3 feet in front of the
listening position with the null baffle
turned to the point at the listening
position would work best. Further
guidance can be had from your
certified THX
®
dealer.
NOTE:  Do not attempt to install any
type of mounting brackets onto
your speakers. Drilling holes in the
product or improperly installing
mounting brackets may void your
JBL warranty and cause a safety
hazard.  
A JBL factory authorized custom
installer can suggest and install
appropriate brackets. Contact JBL
or your installer/dealer for
additional information. 
CONNECTIONS
To connect the loudspeaker
systems to the receiver or
amplifier, use two-conductor
insulated wire. Your JBL dealer 
can recommend suitable cables,
or you can buy wire at most
hardware stores. High-quality
connectors and cable offer
consistent performance that won't
deteriorate over time. We
recommend #16 AWG wire as a
minimum size. If your speakers 
are more than 30 feet (10 m) from
your receiver or amplifier, use
larger diameter wire. Make
connections at the terminals
located on the back of the
loudspeaker system. The
terminals accept bare wire or dual
banana plugs, either of which will
provide easy, secure connections.
