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 or visit www.infinitysystems.com for assistance.
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.
