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).
