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 integrates smoothly with the
entire system. Setting the subwoofer's volume level too high will result in an over-
powering, boomy bass. Setting the volume level too low will negate the effect of the
subwoofer.
The metal plate acts as the heat sink for the subwoofer's internal amplifier. Do not place
pillows or other objects against it.
We recommend placing the subwoofer at least 2 to 3 feet away from a television or a
computer's disc-drive system to prevent smearing the colors of the TV picture or
erasing of the magnetic drive.
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 non-
directional 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 non-directional, the fact is that when installing a subwoofer
within the limited confines of a room, reflections, standing waves and absorption
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). Never place the port too close to a wall or piece of furniture as this will prevent
the port from operating properly. Since the port is an integral part of the subwoofer's
design, it should always be permitted free access to the listening room without
obstruction to the sound emerging from it. Careful experimentation will enable you to
determine the best position for the subwoofer (see useful hints, next page).
