PLACING THE SUBWOOFER
The performance of a subwoofer is directly related to its placement in the listening room
and its physical position relative to the other speakers in the system.
While it is true that in general our ears do not hear directional sounds at the low frequencies
where subwoofers operate, when installing a subwoofer within the limited confines of a
room, the reflections, standing waves and absorptions generated within the room will
strongly influence the performance of any subwoofer system. As a result, the specific
location of the subwoofer in the room does become important to the amount and quality of
bass that is produced.
For example, placing the subwoofer next to a wall generally will the increase the amount
of bass in the room; placing it in a corner (1) generally will maximize the amount of bass in
the room. However, corner placement can also increase the destructive effect of standing
waves on bass performance. This effect can vary depending on the listening position -
some listening positions may yield very good results while others may have far too much (or
too little) bass at certain frequencies.
In many rooms, placing the subwoofer along the same plane as the left and right speakers (2)
can produce the best integration between the sound of the subwoofer and that of the left
and right speakers. In some rooms, the best performance could even result from placing
the subwoofer behind the listening position (3).
We strongly recommend that you experiment with placement before choosing a final
location for your subwoofer. One way you can determine the best location for the subwoofer
is by temporarily placing it in the listening position and playing music with strong bass
content. Move around to various locations in the room while the system is playing (putting
your ears where the subwoofer would be placed), and listen until you find the location
where the bass performance is best. Place the subwoofer in that location.

• Be sure to turn the Crossover on the subwoofer fully
clockwise when LFE output is used. This setting
uses your receiver or processor's crossover.
• Check your receiver or processor menu settings and
set the subwoofer selection to 'On' or 'Yes.'
Please be sure to review the owner's manual for your
receiver or processor for more information on speaker
setup and configuration.

• We recommend setting the subwoofer's Crossover
setting to 00Hz for mid-sized speakers, higher for
smaller (satellite) speakers, and lower for larger
floorstanding speakers.
