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 either your dealer or
Infinity’s Customer Service Department for advice.
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.

acts on installation that may prove
useful.
It is generally belie
ved by most audio authorities that low
frequencies (below 125Hz) are nondirectional and, therefore,
placement of a subwoofer within any listening room is not
cr
itical.W
hile in theor
y it is true that the lar
ger wavelengths of
e
xtr
emely 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 str
ongly inf
luence the perfor
mance of any
subwoof
er system.As a r
esult, the 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).

the right-channel satellite speaker to re-create the actual
location of bass instruments in an orchestra and/or add impact
