CAUTION: The metal plate on
the back of the subwoofer
acts as the heat sink for the
subwoofer’s internal amplifier.
It is normal for this area
to get warm.
PLACEMENT
NOTE: The satellite speakers can be placed directly on a shelf, or mounted on a wall using the
built-in bracket (see Figures 3 through 6).
For front left and right channels, place the speaker on the left and another on the right.
For the center channel, place the speaker directly on top of, or below, your television.
Since the speakers are magnetically shielded, you can place them very close to the TV without
worrying about the magnetic field distorting the TV picture.
For surround left and right channels, place one speaker on the left and another on the right, to
the side of, or behind the listening area.
Since installing a subwoofer can be somewhat more complicated than installing full-range
speakers, it is essential 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 integrates 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 effect of the subwoofer.
We recommend placing the subwoofer at least 2 to 3 feet away from a television or a computer’s
disc-drive system to prevent distorting the colors of the TV picture or erasing the magnetic drive.
Here are several additional facts on installation that may prove useful. It is generally believed 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 the 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. 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 pressure emerging from
it. Careful experimentation will enable you to determine the best position for the subwoofer (see
useful hints, next page).
