POSITIONING
The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That's why
positioning generally doesn't present any problems. However, it is preferable to place the speaker close
to the front loudspeaker in front of the listening position. You should also make sure that the distance
from the sides to items and walls is at least 30 centimetres and at least 20 centimetres from the rear as
otherwise bass reproduction may be impaired.
