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-

the correct polarity remains

and directionality of the
program material.
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
(–) terminal on the speaker, and
the (–) terminal on the amplifier
to the (+) terminal on the
speaker.

To use the push-type terminals
on the connections panel sup-

“back box” enclosure, depress
the colored cap until the pass-

is revealed. While holding the
cap down, insert the bare end

Since the HTI88 is a passive
loudspeaker, only speaker-level
connections are available.
Depending on whether you are
using a dedicated subwoofer
loudspeaker, only speaker-level
connections are available.
