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 satellite speakers reproduce the
high, midrange, and upper-bass frequen-
cies, the subwoofer’s bass reflex design
provides a clean response in the crucial
bottom octave of the audible range. This
results in heightened presence and clarity
for the entire audio range.
The subwoofer’s low-bass sounds are
produced by a down-firing 10-inch driver
with a 11/2-inch dual-voice coil. Each sat-
ellite speaker has a 31/2-inch woofer with
a 1/2-inch liquid cooled soft-dome tweeter
in a separate enclosure that swivels so
you can adjust it for the best stereo imag-
ing.
SPEAKER PLACEMENT
Choosing a Location for the
Satellites
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 be-
tween the speakers.
If you place the speakers too far apart,
you might hear a “hole” in the center ofthe
sound. Compensate for this by angling the
speakers slightly in toward the listening
area.
If you place the speakers too close togeth-
er, you will cancel out the stereo image.
Compensate for this by angling the speak-
ers slightly away from the listening area.

Tables or shelves near a corner are ideal
locations —for example, adecorator shelf
attached to a wooden wall (or other
acoustically hard surface). If possible,
place the front ed
g
e of the speakers flush
with the front ed
g
e of the shelf. Avoid floor
locations, since floor coverin
g
s can ab-
sorb many of the hi
g
her frequency
sounds.
Note: We recommend you play a wide-
ran
g
e recordin
g
and experiment with
speaker placement until you find the
speaker locations that provide the best
sound for your needs.
Choosing a Location for the
Subwoofer
Because low frequencies are much less
directional than other sounds, you can
use the sin
g
le subwoofer and place it al-
most anywhere in your listenin
g
area.
However, to simplify connections, you can
place the subwoofer between the left and
ri
g
ht satellite speakers.
CONNECTIONS
With the speakers positioned as desired,
measure the distance from the subwoofer
to each satellite speaker, and from the
subwoofer to your amplifier. Cut speaker
wire to the needed len
g
ths, includin
g
about a foot of extra wire at each end for
preparin
g
the wires (see “Preparin
g
the
Wires”) and occasionally movin
g
the
speakers.
Notes:
• Use 18-
g
au
g
e speaker wire for dis-
tances up to 25 feet. Use 16-
g
au
g
e
(or lar
g
er) wire for distances
g
reater
than 25 feet.
• Your local Radio Shack store sells a
wide selection of speaker wire.
Preparing the Wires
1. Split each speaker wire’s two con-
ductors about 4 inches from each
end.
2. Remove 1/2-inch of insulation from
each conductor’s end and twist the
strands at each end.
3. Route the speaker wires from the
amplifier to the subwoofer. Then
route the satellite speaker wires to
the subwoofer.
Connecting the Wires
For minimum si
g
nal loss, maximum bass
response, and best overall performance,
connect your subwoofer’s positive (red)
and ne
g
ative (black) terminals to the
matchin
g
terminals on your satellite
speakers and amplifier that have the
same polarity.

To help you make the proper connec-
tions, one side of each pair of speaker
wire conductors 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 conduc-
tors are brass and silver. Use the brass
wire as the positive (+) polarity wire.
1. Connect your amplifier’s left and
right OUTPUT speaker terminals to
the subwoofer’s INPUT terminals.
2. Connect the left satellite speaker’s
wires to the subwoofer’s LEFT OUT-
PUT terminals.
3. Connnect the right satellite
speaker’s wires to the subwoofer’s
RIGHT OUTPUT terminals.
Caution: Do not exceed this system’s
power handling capacity (see “Specifica-
tions”). To avoid damage to the speaker
system, set the amplifier’s volume to its
lowest setting beforeoperating the stereo
system’s controls.
Note: You can use the H/L (high/low)
switch on the back of each satellite to ad-
just the tone of the satellites’ tweeters. Set
H/L toH for a “bright” sound,or Lfora“flat”
sound.
CARE AND
MAINTENANCE
Your Optimus PRO SWS-502 Satellite
Subwoofer Speaker System is an exam-
ple 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 care-
fully. Dropping it can damage it and
cause it to work improperly.
• Keep the system dry. If it gets wet,
wipe it dry immediately. Liquids con-
tain minerals that can corrode elec-
tronic 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: You might permanently damage
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.
