POSITIONING

Since the installation of a subwoofer is 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.

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 BU-2 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 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 non-directional, 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). 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).
