• 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
PB10 and PB12 powered
subwoofers, 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 with bare
wire, unscrew the collar until
the hole through 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:
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” to the cor-
responding 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.
