SPEAKER PLACEMENT
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 loudspeakers. Use these
placement recommendations
as a guide. Slight variations
will not diminish your listening
pleasure.
INTRODUCTION
JBL’s HT Series takes advantage
of our latest technology to deliver
incredibly clean, detailed sound.
Incorporating JBL’s symmetrical
array design and exclusive BiRadial
®
horn, these loudspeakers
deliver sound that is distributed
over a wide soundstage with
pinpoint imaging, and the HT4V is
THX
®
Ultra certified. The horn
should be directed at ear level in
order to maximize the imaging
characteristics. The Bi-Radial
horn design – which greatly
reduces room reverberation –
along with video-shielding, allows
greater placement flexibility within
the room. Ultrawide frequency
response and high power handling
combine to give you clear,
powerful sound that you get only
from genuine JBL. The HT
loudspeakers are perfect for
today’s Dolby* Digital and DTS
®
recordings.
The HT4H center-channel
loudspeaker is designed to
complement any of the HT Series
loudspeakers. It is the perfect
addition for re-creating the
cinematic experience in your hom
e.
As Front Speakers
HT4V
For optimum performance, use the
HT4H with the grille attached.
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, or they may be angled
toward the listeners.
The HT4H center-channel speaker
should be placed slightly behind
the front left and right speakers,
and no more than two feet above
or below the tweeters of the left
and right speakers. It is often
convenient to set the center
speaker on top of the television
set, as shown in the drawing.
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 the corners of
the room behind the listening
position, angled in toward the
center of the listening area. The
customer is responsible for proper
selection and use of mounting
hardware, available through
hardware stores, to properly and
safely wall-mount the speakers.
The surround speakers should not
call attention to themselves.
Experiment with their placement
until you hear a diffuse, ambient
sound accompanying the mainprogram material heard in the
front speakers.

SPEAKER FEET
HT4H
The HT4H terminal cup has an adjustable foot to angle the speaker toward the listening position.
Loosen thumbscrew.
Slide rod down the desired
amount.
Tighten thumbscrew.
Separate and strip the ends of the
speaker wire as shown. 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. The (+) lead of the
speaker wire is noted with a
stripe. 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 multichannel
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.
Connection Tips
If there is no sound from
any of the speakers:
• Check that receiver/ amplifier is
on and that a source is playing.
• Review proper operation of your
receiver/amplifier.
• Make sure all wires are
connected. Make sure none of the
speaker wires are frayed, cut or
punctured.
If the system plays at low volumes
but shuts off as volume is
increased:
• Check all wires and connections
between receiver/amplifier and
speakers.
• If more than one pair of main
speakers is being used, check the
minimum impedance requirements
of your receiver/amplifier.
• Make sure all wires are
connected. Make sure none of the
speaker wires are frayed, cut or
punctured.
If there is no sound coming from
one speaker:
• Check the “Balance” control on
your receiver/ amplifier.
• Check all wires and connections
TROUBLESHOOTING
HT4V
Both the HT4V and HT4H come
with rubber, self-adhesive
footpads, which should be
attached to the bottom corners of
each speaker to protect both your
furniture and the speakers.

• If your receiver/processor
is set in Dolby Digital or DTS
mode, make sure the receiver/
processor is configured so that the
center speaker is enabled.
If there is no (or low) bass output:
•
Make sure the polarities (+ and –)
of the left and right “Speaker
Inputs” are connected properly.
• If a powered subwoofer is being
used, check the manufacturer’s
instructions for proper use.
• If a subwoofer is being used in
Dolby Digital or DTS modes, make
sure your receiver/processor is
configured so that the subwoofer
and LFE output are enabled.
If there is no sound from the
surround speakers:
• Check all wires and connections
between receiver/ amplifier and

check to see if your receiver/
amplifier has other surround
modes you may use.
• In Dolby Digital or DTS modes,
make sure your receiver/
processor is configured so that the
surround speakers are enabled.
• Review the operation of your
DVD player and the jacket of your
DVD to make sure that the DVD
features the desired Dolby Digital
or DTS mode, and that you have
properly selected that mode using
both the DVD player’s menu and
the DVD disc’s menu.
