Placement
Place the subwoofer next to a wall or in a corner near your main speakers. Typically, the sound is best when the subwoofer
is within 15 feet (5m) of the main speakers. However, the sharp 24dB/octave crossover roll-off permits placement farther
from the main speakers if necessary. Since the ear is unable to localize the low frequencies of the subwoofer, the bass still
appears to come from the main speakers. In most cases, the subwoofer may be placed anywhere in the listening room.
The level of bass output from the subwoofer will vary at different positions in a room. When placed near walls, its loud-
ness is emphasized. Corner placement provides the most bass output, while placement near only one wall will provide
somewhat less bass. Placement completely away from walls may produce too little bass. Regardless of how you place the
subwoofer, you can adjust the subwoofer’s level with its volume control. If you move the subwoofer, recheck the setting of
the polarity switch. Use the setting that yields the louder and more dynamic sound.
IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear panel and drapes or
furniture.
