PRO SWS-502 Satellite Subwoofer Speaker System
Your Optimus PRO SWS-502 Satellite
Subwoofer Speaker System is designed
to add the dramatic realism of solid bass
(below 200 Hz) to your sound system.
While the sat ellit e speakers r eproduce the
high, midrange, and upper-bass frequencies, the subwoofer’s bass reflex design
provides a clean response in the crucial
bottom octave of the audible range. This
results i n heightened pre sence and clarit y
for the entire audio range.
The subwoofer’s low-bass sounds are
produced by a down-firing 10-inch driver

Location and position are vital for the best
sound performance of your satellite
speakers. For the best stereo image, the
distance between the speakers should be
about the same as the distance from the
main listening area to a point halfway between the speakers.
If you place the speakers too far apart,
you might hear a “hole” in t he center of the
sound. Compensate f or this by a ngling th e
speakers slightly in toward the listening
area.
If you place th e speakers to o close toget her, you will cancel out the stereo image.
Compensate for thi s by angli ng the speakers slightly away from the listening area.

To help you make the proper connections, one side of each pair of speaker
wire conductor s is marked with a stripe or
groove, normally considered the positive
(+) polarity wire.
Note
: The insulation in some speaker
wires is clear, and the separate conductors are brass and silver. Use the brass
wire as the positive (+) polarity wire.

CARE AND
MAINTENANCE
Your Optimus PRO SWS-502 Satellite
Subwoofer Speaker System is an example of superior design and craftsmanship.
The following suggestions will help you
care for the system, so you can enjoy it for
years.
• Handle the system gently and carefully. Dropping it can damage it and
cause it to work improperly.
• Keep the system dry. If it gets wet,
wipe it dry immediately. Liquids contain minerals that can corrode electronic circuits.
• Wipe the system occasionally with a
cloth dampened with furniture polish.
This helps to keep it looking new. Do
not use harsh chemicals, cleaning
solvents, or strong detergents to
clean the speaker cabinet.
Caution
your system by cleaning it with a vacuum
cleaner. Use a feather duster or a very
soft loose cloth instead.
Modifying or tampering with the speaker
system’s internal components can cause
a malfunction and might invalidate the
warranty. If the system is not performing
as it should, take it to your local Radio
Shack store for assistance.
: You might permanently damage
