Infinity BU-80 - Manual (Page 6)

Figure 1. This view shows the
subwoofer positioned behind the
right-channel satellite speaker to
re-create the actual location of
bass instruments in an orchestra.
Here are some useful hints:
1. Experimentation with the port direction may be useful. At times directing the port away
from the listening area (to the side) may be advantageous because this may create a better
blend of bass within the listening room.
2. If bass response seems inadequate, move it closer to a wall or corner. If bass becomes too
heavy, try turning the subwoofer with the port facing away from the wall. This will tend to
diminish bass output.
It will take time and patience to find the most pleasing acoustic location for your subwoofer.
Testing for sonic balance and blending should always be made for your normal listening
position, using a wide range of source material. As a starting point, initially place the subwoofer
behind your right-channel satellite speaker, about 3 or 4 inches from the wall. We suggest
trying this location first because in an orchestra, the bass instruments are usually located in the
back and to the right (see Figure 1).
