Positioning the speakers
How you set up your speakers can affect the bass and the sound field.
Note the following points:
- Place the speakers on flat secure bases.
- Placing speakers too close to floors, walls, and corners can result in
excessive bass. Cover walls and windows with a thick curtains.
Note
Keep your speakers at least 10 mm away from the system for proper ventillation.
Place the front, center and surround speakers at approximately the same distance from the seating
position.
The angles in the diagram are approximate.
Front speakers (left, right)
Place on the left and right of the TV at seated ear height so that there is good coherency between the
picture and sound.
Center speaker
Place underneath or above the center of the TV. Aim the speaker at the seating area.
Surround speakers (left, right)
Place on the side of or slightly behind the seating area, higher than ear level.
Subwoofer
The subwoofer can be placed in any position as long as it is at a reasonable distance from the TV.
Note that some experimentation can yield the smoothest low frequency performance. Placement near a
corner can increased the apparent output level, but can result in unnatural bass.
If irregular colouring occurs on your television
The supplied speakers are designed to be used close to a television, but the picture may be affected
with some televisions and setup combinations.
If this occurs, turn the television off for about 30 minutes
9

The television’s demagnetising function should correct the problem. If it persists, move the speakers
further away from the television.
