PLACEMENT

Since the installation of a subwoofer can be somewhat more
complicated than installing full-range speakers,it is essential
that you read this section very carefully prior to connecting the
subwoofer to your system.Should you have questions relating to
your installation,it is advisable to call your dealer.

The performance of the subwoofer is directly related to its
placement in the listening room and how you align the subwoofer
with its satellite speakers.Setting the volume of the subwoofer in
relationship to the left and right speakers is also of critical
importance because it is essential that the subwoofer integrate
smoothly with the entire system.Setting the subwoofer’s volume
level too high will result in an overpowering,boomy bass.Setting
the volume level too low will negate the benefits of the
subwoofer.

Here are several additional facts on installation that may prove
useful.It is generally believed by most audio authorities that low
frequencies (below 125Hz) are nondirectional and,therefore,
placement of a subwoofer within any listening room is not
critical.While in theory it is true that the larger wavelengths of
extremely low frequencies are basically nondirectional,the fact is
that,when installing a subwoofer within the limited confines of a
room,reflections,standing waves and absorptions generated
within the room will strongly influence the performance of any
subwoofer system.As a result,specific location of the subwoofer
becomes important,and we strongly recommend that you
experiment with placement before choosing a final location.

Placement will depend upon your room and the amount and
quality of bass required (for example,whether or not your room
permits placement of the subwoofer near either satellite).Be
sure to leave a minimum of six inches between the wall and the
port on the subwoofer.

Figure 1. This example shows the subwoofer positioned behind
the right-channel satellite speaker to re-create the actual
location of bass instruments in an orchestra and/or add impact
to movie soundtracks.
