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 increase the amount of
bass in the room; placing it in a corner (1) generally will maximize 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.
MAKING CONNECTIONS
CAUTION: Never make or break connections unless all
system components are powered off.
CONNECTING TO AN AV SURROUND RECEIVER OR
PROCESSOR WITH AN INTERNAL CROSSOVER
If you are connecting to a surround processor with a low-pass filtered
subwoofer output, connect the subwoofer as shown below. You can
make either a balanced (XLR) or unbalanced (RCA) connection to
either the subwoofer's
left
or right input connector.
When connecting
to surround processors with internal crossovers, set the Low
Pass crossover control knob to the
"LFE"
position.
