Precaution on use
Adding a subwoofer to your speaker system expands the bandwidth of reproduced bass-range sound. If the subwoofer’s
reproduction bandwidth or sound output level is improperly adjusted, however, the overall performance may be decreased
as shown in the graphs below.
Placement
• The enclosure is made of wood and therefore sensitive to
extreme temperatures and humidity. Avoid placing the unit in
locations subjected to direct sunlight or in humid places such as
near an air conditioner, bathroom or kitchen, as well as in
locations subjected to soot or steam such as near a kitchen
table and humidifier. Otherwise, damage may occur.
• Keep water or other liquids away from the unit. If water is spilled
into the unit, not only the unit but also the connected receiver
(amplifier) may be damaged.
• Place the unit on a level and rigid surface free from vibration.
The placement of the SKW-205 can greatly affect the
sound that is produced. Under normal circumstances,
placement in the corner of the room provides the best
results.
Note:
Be careful not to allow the input of excessive power. Input
levels that greatly exceed normal situations can damage
the SKW-205. Also note that switching operations at the
amplifier can also cause excessive noises that may cause
damage. When using switches at the amplifier, first lower
the volume to prevent accidental damage.
Crossover frequency and output level
• Adjust the SKW-205 output level and the crossover fre-
quency properly for your listening room and connected
speakers.
• When the unit is connected to an amplifier via the speaker-
level input (INPUT FROM AMP/RECEIVER) terminals,
setting the OUTPUT LEVEL knob near the center position
will provide a well-balanced sound level with most speakers.
• Note that you may possibly set the subwoofer at high output
levels because superbass-range sound is not so audible as
sound in other ranges. To obtain well-balanced frequency
characteristics, set the output level to a slightly lower level
than seems optimal. (This will also prevent the input of too
strong signals.)
• Four slip-proof spacers are provided with the SKW-205. If the
SKW-205 is to be placed on flooring or other similar surfaces,
attach these spacers to the bottom surface at the corners. This
will not only prevent scratching, but also provide a stable
footing. However, note that depending on the surface, the
spacers may leave markings.
• This unit is designed to be used in the upright vertical position
only. Do not use it in the horizontal or tilted position.
• If the unit is used near a turntable or CD player, howling or
skipping of sound may occur. To prevent this, move the unit
away from the turntable or CD player or otherwise lower the
unit’s output level.
