Placement  
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 cant  
tell where they are generated  
from. However, frequencies  
between 75Hz – 150Hz can  
be localized, especially at  
higher volume levels.  
Positioning your subwoofer  
as recommended will provide  
the most natural soundstage  
and imaging from your loud-  
speaker system.  
Remember that these are just  
guidelines. Since every listen-  
ing room is different, JBL  
strongly recommends experi-  
menting 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 tem-  
porarily place the subwoofer  
near the main listening loca-  
tion. 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  
PSW-D110 powered subwoofer,  
our goal was to offer the user  
the best possible performance  
combined with the 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 corre-  
sponding hookup instructions.

Note: Some receivers/ ampli-

case, it is recommended that  
you use a “Y-connector (not

3) If your receiver/ ampli-  
fier has preamp output  
jacks and main input  
hooked up as shown above,  
the subwoofer will limit the  
low-frequency information  
that is returned to your  
receiver/ amplifier. Your  
receiver/ amplifier does  
not need to waste valuable  
power reproducing the low  
frequencies. In addition,  
since no low-frequency  
information is being sent  
to your main loudspeakers,  
they are able to reproduce  
mid and high frequencies with  
greater clarity.

Operation  
Power  
Level Control  
When the unit is plugged in  
and no signal is received  
for approximately 10 – 15  
minutes, the subwoofer will  
go into a standby mode until  
a signal is present. Due to  
JBLs unique, high-efficiency  
digital-amplifier design,  
The subwoofer Level Control,  
located on the front panel,  
adjusts the volume of the  
subwoofer relative to the rest  
of the system. Proper level  
adjustment depends on several  
variables such as room size,  
subwoofer placement, type of  
main speakers and listener  
position. Adjust the subwoofer  
level so that the volume  
of the bass information is  
pleasing to you.  
power consumption is minimal  
when the subwoofer is not  
receiving a signal.  
Crossover Adjustments  
High-Pass Control  
Low-Pass Control  
speakers that do not extend  
to the lower bass frequencies,  
set the high-pass crossover  
control to a higher setting,  
between 125Hz – 180Hz.  
With this setting, your main  
speakers will not have the  
burden of reproducing any  
low-frequency sounds.  
• If you hooked up your sub-  
woofer as shown in Hookup  
1 on page 3, the high-pass  
frequency is fixed at 180Hz.  
• If you hooked up your sub-  
woofer as shown in Hookup  
2 on page 4, there is no  
high-pass control. Unless  
your receiver/ amplifier  
Final adjustment and blending  
of the low-pass and high-pass  
controls may evolve over sev-  
eral listening sessions. A good  
starting point would be to set  
both the low- and high-pass  
controls to the same frequency  
and adjust from that point.  
• If you hooked up your sub-  
woofer as shown in Hookup  
3 on page 4, you also have  
the capability of adjusting  
the high-pass frequency.  
The High-Pass control  
determines the frequency at  
which the main speakers  
will start reproducing  
sounds. If your main speak-  
ers can comfortably repro-  
duce some low-frequency  
sounds, also set this con-  
trol to a lower frequency  
setting, between 50Hz –  
100Hz. This will concen-  
trate the subwoofers  
efforts to the ultradeep  
bass sounds, while your  
main speakers continue to  
reproduce the mid-bass  
information. If you are

The Low-Pass control deter-  
mines the highest frequency at  
which the subwoofer reproduces  
sounds. If your main speakers  
can comfortably reproduce

set this control to a lower  
frequency setting, between  
50Hz – 100Hz. This will

films and music. If you are
