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.
