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 loudness 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 level control. If you move the subwoofer, recheck the setting of the polar-
ity 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 heat sinks and drapes or furniture. Avoid obstructing air flow to the back.
