Place the QBX Sub 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.
The level of bass output from the QBX Sub 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 QBX Sub, you can
adjust its level with the level control. If you move the QBX Sub, recheck the setting of the
polarity switch. Use the setting that yields the louder and more dynamic sound.
IMPORTANT: Do not place the QBX Sub where there is a chance of contact between the rear
panel amplifier plate and drapes or furniture. Avoid obstructing air flow to the back of the unit.
