SUBWOOFER SERIES PLACEMENT

Placement

Your DUAL subwoofer can be placed in many convenient
locations in your home, but must be placed on the floor. Do
not attempt an installation that would elevate the subwoofer
above floor level. You should experiment with various place­ments. Room Acoustics can produce large apparent differ­ences in the sound for small changes in the placement
location and adjustments to subwoofer controls. For
Example, directing the woofer of a forward firing sub toward
one’s typical listening position and adjusting the low pass
filter to 150 Hz can make the sub very directional. This
means you perceive exactly where the sub is located within
the room. This is not a desirable result for the most realistic
audio experience.

The common thinking regarding subwoofer placement and
performance is to position and adjust the subwoofer in such
a way that the subwoofers low frequencies encompasses
the entire room with deep powerful bass and provides the
most realistic imaging experience. The amount of bass per­ceived increases as you move the subwoofer closer to an
intersecting wall surface and the highest level of bass
results are realized from placement in a corner, but should
be no closer than 3" from the wall surface. The floor and
corner placement (loading) are actually an important part of
the Subwoofer’s design. Attempt to place the subwoofer in
or near the corner closest to your system's receiver to
ensure the shortest possible wire or cable runs, which will
result in superior performance.
