PRO SW-120 12-Inch 100-Watt Subwoofer  
System  
Your PRO SW-120 12-Inch 100-Watt  
Subwoofer System is designed to add  
the dramatic realism of solid bass re-  
sponse (below 150 Hz) to many  
speaker systems. The subwoofer sys-  
tem’s bass reflex design provides  
clean bass response in the crucial bot-  
tom octave of the audible range.  
coil. This lets you connect both ste-  
reo channels to a single subwoofer  
system.  
While your PRO SW-120 can work  
with most speaker systems, it is de-  
signed to give the best results with  
RadioShack PRO-X7s (Cat. No. 40-  
2071), PRO-X77s (40-2077), or PRO  
LX5 (Cat. No. 40-4061) speakers.  
The subwoofer system’s effect is most  
dramatic when it is combined with  
mini-speakers. The mini-speakers re-  
produce the high, mid-range, and up-  
per bass frequencies, while the  
subwoofer reproduces the low bass  
frequencies. This results in height-  
ened presence and clarity for the en-  
tire audio range.  
Because low frequencies are much  
less directional than other sounds,  
you can use a single subwoofer for  
both stereo channels. You can put  
the subwoofer almost anywhere in  
your listening area. However, to sim-  
plify connections, we recommend  
you place the subwoofer between  
the left and right front stereo speak-  
ers.  
The subwoofer has a front-firing 12-  
inch driver with a dual 2-inch voice

MAINTENANCE  
The following suggestions will help you care for the speaker system so you can en-  
joy it for years.  
Keep the subwoofer dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.

gents to clean the subwoofer.  
Caution: You might permanently damage your subwoofer by cleaning it with a vac-  
uum cleaner. Use a feather duster or a very soft cloth instead.
