The appropriate positions for Performance Series speakers within the installation space will depend on their application. Position guidelines and diagrams for Performance 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 Performance 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 Performance 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 Performance 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.
Performance 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 Performance 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 Performance Series in-wall speakers are utilised in multi-channel home theatre 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.
The P4-LCR50 is designed specifically for left, right and centre channel applications in multi-channel home theatre installations. It should be mounted in portrait orientation for left and right channel use, and in landscape orientation for centre channel use.
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.
