Subwoofer effects

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.

Adjustments

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.)

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.

Precaution on use

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.

•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.
