Surround Speaker Placement
While each loudspeaker in an AV system should be located
appropriately in its immediate acoustic environment, correct
positioning will offer the best chance of programme material
being heard as intended. The basic guidelines for positioning the
full bandwidth speakers of a 5.1 or 7.1 system are illustrated in
Fig 2. The elements of an AV system should follow this
positioning guide as closely as possible although there is some
latitude for compromise in the speaker to listener distance of a
domestic installation as AV coders/processors provide facilities
to adjust the delay time of all or some speaker channels.
Acoustic Axis and Height Positioning
The loudspeakers should be mounted with the acoustic axis
at or slightly above ear height. The acoustic axis of each
loudspeaker is shown opposite:

Each HTS loudspeaker is equipped with a “single pair”
connection panel. The terminals can accommodate either
stripped bare cable ends, 4mm banana plugs or spade terminals.
Always use a good quality speaker cable with minimum cross
sectional area per conductor (minimum 79 strand). For cable
runs longer than 5 metres use a significantly heavier gauge cable.
Consult your dealer or consultant for specific cable
recommendations.
Ensure that the positive and negative terminals on each
connection panel are connected to the corresponding positive
and negative terminals on the amplifier. A lack of bass output
and very wide unstable stereo image is most likely caused by the
left and right loudspeakers being connected out of phase. If the
system displays these characteristics, please check the polarity
of the wiring.

All loudspeakers should be equi-distant from the listening position:
distance L = distance C = distance R = distance LS = distance LR = distance RR
•
For 5.1 systems, position the ‘surround’ speakers between 110 and 150 degrees
•
If ideal positioning is not possible, position loudspeakers as close as possible
Fig. 2
Ideal Full Bandwidth Speaker Positioning of 5.1 and 7.1 systems
All loudspeakers should be equidistant
from the listening position: distance L=C=R=LS=LR=RR=RS.
For 5.1 systems, position the surround speakers between 110° and 150° (ITU spec. is 110°).
The LR and RR speakers shown are applicable to 7.1 systems only.
If ideal positioning isn’t possible, position loudspeakers as close as possible to ideal.
