• As a general rule, bass
response increases as a
subwoofer is placed closer
to a wall. Therefore, bass
output is maximized when
the subwoofer is placed in
a corner.
• It is also recommended that
the subwoofer be
positioned along the
same wall as the front
loudspeakers.
Low-frequency sounds are
normally omnidirectional,
meaning the listener can’t tell
where they are generated
from. However, frequencies
between 75Hz – 150Hz can be
localized, especially at higher
volume levels. Positioning
your subwoofer as recom-
mended will provide the
most natural soundstage
and imaging from your
loudspeaker system.
Remember that these are just
guidelines. Since every
listening room is different,
JBL strongly recommends
experimenting with the
positioning of your subwoofer
to obtain the most pleasing
results in your room. One
technique that can help you
find the ideal subwoofer
location is to temporarily
place the subwoofer near the
main listening location. Then
move around the room and
determine where you hear
the most pleasing bass
performance. This would then
be the ideal location for the
subwoofer.
When we designed the
S120P
II powered subwoofer,
our goal was to offer the user
the best possible performance
combined with the most
flexible and complete
installation options. Please
look over the following three
examples to determine which
description best matches
your system and follow the
corresponding hookup
instructions.
To use the binding-post
speaker terminals •ª with
bare wire, unscrew the collar
until the pass-through hole in
the center post is visible
under the collar. Insert the
bare end of the wire through
the hole in the post, then
screw the collar back down
until the connection is tight.
The holes in the center of the
collars are intended for
banana-type connectors.
Dolby* Pro Logic* (Non-Digital) – Speaker Level
Use this installation method
for Dolby Pro Logic appli-
cations (not Dolby Digital,
DTS
® or other digital
processing), where the
receiver/processor does not
have a subwoofer output or
a volume-controlled preamp
(line-) level output:
If your receiver features bass
management capabilities that
require you to configure your
speaker settings, make sure
to set your left- and right-front
speakers to “LARGE”.
Connect your receiver or
amplifier’s front left and right
speaker terminals to the left
and right terminals on the
subwoofer that are marked
“High Level In” •. Connect
the left and right terminals on
the subwoofer that are
marked “High Level Out” ª
to the corresponding
terminals on the back of your
front left and right speakers.
Connect your receiver or
amplifier’s center, left and
right surround-speaker
terminals to the corre-
sponding terminals on the
back of your center, left and
right surround speakers.
