2. In-ceiling Speaker Positioning
Aelite Custom Install
speakers are intended to be used in high quality
In-ceiling
distributed audio systems or as surround speakers in home-theatre systems.
The location of speakers within a listening environment is likely to have more
influence over their subjective performance than any other aspect of installation. It
is worth spending some time considering both the finer points of speaker location,
as well as the larger scale issues of room and speaker layout.
Almost certainly your speakers will be used in one of two applications:
•
As surround speakers in a Home theatre system where the location of
speakers relative to each other is important.
•
In utility "background sound" applications where single speakers are used
in isolation to "cover" a specific area or areas.
These two types of application are covered in the paragraphs below.
Aelite Custom Install speakers are magnetically shielded so may be positioned in
relatively close proximity to magnetically sensitive equipment and media.
Home Theatre Speaker Positioning
If two or more speakers are to be used for the surround channels in a home theatre
system they should be positioned approximately as follows:
•
In-line with and behind (in 7. systems) the listening position.
•
All approximately equidistant from the listening position.
•
A minimum of .5m from the listening position but at least 0.5m away from
walls.
Utility Speaker Positioning
If your Aelite Custom Install In-ceiling speakers are to be used as multiple "utility"
speakers in an environment where the intention is to provide background music
they should be equally distributed throughout the space. In-ceiling speakers should
be kept a minimum of 0.5m away from walls.
Mono audio is usually preferable in utility applications but if only stereo is available
multiple speakers in the same room or zone should be connected alternately to the
left and right channels.
In choosing locations for the speakers consider the "coverage" required with respect
to the likely listener positions. Try and ensure that coverage is even and that as
listeners move around the environment the sound from one speaker is gradually
"replaced" by the sound from the next nearest speaker. The overall volume should
be relatively constant.

Caution
When cutting apertures in walls or ceilings ensure that
pipes and cables are clear. Ensure also that the structure
of the walls will safely carry the weight of the speakers.
If you are unsure about any aspect of installation you
should seek professional advice and assistance.
