Front and Effects Channels: The front loudspeakers are placed on either side of the
television screen, 2 to 3 metres apart. The speakers should be angled slightly so they are
aimed towards listeners. We recommend placing the rear effects speakers in a high
position, behind the listener's head. If the rear or side walls are a long way from the
listening seat, consider stand mounting the loudspeakers. If the centre loudspeaker is
very high or low, angle it towards the listener's ear level.
The front faces of the centre and surround loudspeakers should also be in line as far as
possible.
Subwoofer: As the ear is unable to detect the direction from which deep bass originates,
you have freedom to position the unit. Varying the distance from the wall alters the bass.
Placing the subwoofer across a corner boosts the bass but may impair clarity. The
performance of a home theatre system can be enhanced by using two subwoofers.
Dolby Labs, DTS and THX offer 6.1 and 7.1 format. Although the precise configuration of
these systems will depend on the capabilities of your processor and you should be
guided by those instructions, we would make some observation.
For 6.1 and 7.1 formats the listening seat should not be too close to the rear wall.
Optimising the time delay so that information from all speakers arrives the listening seat
coherently is critical of the benefits of these systemsare to be fully realised.
Dolby Labs Recommended Placement for Multichannel Home Theater Systems.
