PRO SW-14 12-Inch 100-Watt Subwoofer
The subwoofer has a down-firing 12inch driver with a dual 2-inch voice
coil. You can connect both stereo
channels to a single subwoofer.

can use a single subwoofer for both
stereo channels and you can put the
subwoofer almost anywhere within
your listening area. However, to sim-
Your Optimus PRO SW-14 12-Inch
100-Watt Subwoofer is designed to
add the dramatic realism of solid bass
response (below 150 Hz) to many
speaker systems that lack the ability
to reproduce these frequencies on
their own. The subwoofer’s bass reflex
design provides cle an bass response
in the crucial bottom octave of the a udible range.
plify connections, it is usual ly best to
put the subwoofer between the left

The subwoofer’s effect is most dramatic when it is used with stereo
speakers such as RadioShack PRO7s and PRO-77s. The stereo speakers
reproduce the high, midrange, and upper bass frequencies, while the subwoofer reproduces the low bass
frequencies. This results in heightened presence and clarity across the
entire audio range.

ADDING THE SUBWOOFER TO YOUR
SPEAKER SYSTEM
With the subwoofer in t he selected l ocation, measure the distance from it to
each speaker, and to your receiver/
amplifier. Then follow these steps to
connect the subwoofer.
Notes:
• Use 18-gauge speaker wire for
distances up to 25 feet.
• Use 16-gauge speaker wire for
distances greater than 25 feet.
• To maximize the bass response,
you must connect the receiver/
amplifier’s positive (+) and negative (–) terminals to the subwoofer’s corresponding positive
(+) and negative (–) terminals.

You can easily do this by using
speaker wire that has a stripe or a
ridge on one conductor. Your local

selection of speaker wire.
1. Connect the subwoofer’s
terminals to the appropriate left
and right speaker terminals on
your amplifier.
2. Connect the subwoofer’s
PUT
terminals to the correspond-
ing left and right stereo speaker.
