The appropriate positions for Studio Series speakers within the installation space will depend on their application. Position guidelines and diagrams for Studio Series in-ceiling and in-wall models are covered in the following sections and illustrated in the accompanying diagrams.
In-ceiling and In-wall Speakers: If one or more Studio Series speakers are required simply to provide mono background audio, they can be located essentially as dictated by coverage, convenience and architecture. The primary acoustic constraint to consider is that corner positions are likely to result in bass emphasis.
The S4-DVC65 in-ceiling speaker is particularly suited to background sound applications as it can play stereo audio from a single unit.
If a pair of Studio Series in-ceiling speakers are required for stereo audio reproduction, they should ideally be located between 3 m (10 ft) and 5 m (16.5 ft) apart and a similar distance from listening area.
If a pair of Studio Series in-wall speakers are required for stereo audio reproduction, they should ideally be located between 3 m (10 ft) and 5 m (16.5 ft) apart and a similar distance from the listening area. They should ideally be mounted approximately at head height when seated at the listening position or slightly higher.
Studio Series in-ceiling and in-wall speakers can be combined for multi-channel audio installations. In the majority of combined installations, in-wall speakers are best suited to front (left and right) and centre channel applications, and in-ceiling speakers more suited to surround channel applications.
In-ceiling Speakers (Front and Centre channels)
If Studio Series in-ceiling speakers are utilised in multi-channel installations, the front (left and right) and centre speakers should be located approximately 0.5 m (20 in) in front of the plane of the screen. The centre speaker should be on the centre line of the screen and the front (left and right) speakers each within approximately 0.5 m (20 in) of the sides of the screen.
In-wall Speakers (Front and Centre channels)
If Studio Series in-wall speakers are utilised in multi-channel installations, the front (left and right) speakers should ideally be located either side of the screen with each one approximately 0.5 m (20 in) away. The centre channel speaker should be located either directly above or below the screen or, in the case of an acoustically transparent screen, directly behind it.
In-ceiling and In-wall Speakers (Surround channels)
Surround channel speakers should be located as close as possible to the requirements of the specific multi-channel format, usually just behind and at either side of the listening position. The acoustic environment around each speaker and the distance from each one to nearby walls should ideally be similar. Aim to avoid corner positions if possible for any speaker installation.
S4-DVC65 in-ceiling speakers can be used in Dipole mode for surround channel applications. In Dipole mode the twin tweeters of the S4-DVC65 are connected in opposite polarity so that a high frequency acoustic null is generated on the unit’s centrally forward axis. S4-DVC65 units used in Dipole mode should have their bass/mid unit rotated and the tweeter angle adjusted so that they are orientated towards the listening position.
