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.
INSTALLATION
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.
