The placement of your TR-3D subwoofer within the
room is not as critical as speaker placement, since
frequencies of 80Hz and below are non-directional.
However, there are several things you can do to help
you achieve the best performance from your subwoofer.
Ensure that the PHASE control is used properly. As a
•
general rule, if the subwoofer is in front of the
listening position have the PHASE control at 0º.
If the subwoofer is behind the listening position,
then set the PHASE to 180º.
The best performance is usually achieved by placing
•
the subwoofer between your front speakers, facing
the listening position.
Placing near a rear wall will aid the bass response,
•
however avoid corner positioning if possible as this
will result in uneven bass response throughout the
room.
Disconnecting your loudspeakers so you are only
•
listening to bass playback will help as you try to
find areas of the room where bass is overpowering,
or where bass is lacking.
Another tactic would be to select several positions
that will suit the aesthetics of the room, and try each
position in turn to see which position provides the best
response. This settings of the subwoofer can then be
tailored to suit the position.
