Perhaps more than any other audio product, speakers are sensitive to installation 
so please take a little time to read this manual and to follow, as far as practical, the 
installation guidelines it contains. Careful installation will help ensure that your 
speakers perform optimally.
This manual covers the Aego Custom Install Series In-wall and In-ceiling speakers. 
Following this introduction, the Manual is divided into sections covering, 
positioning, connection, installation and listening, We recommend that you read 
at least the first three sections carefully before installing and using your speakers. 
Warranty and contact information is provided on the last page.
Speakers are relatively delicate precision engineered products that can be 
damaged by inappropriate handling. Please take care when unpacking or handling 
the speakers not to touch the drivers. Damage to a driver will at best degrade 
performance and at worst result in complete failure.

Aego Custom Install In-wall speakers are intended to be used in either stereo hi-fi, 
multi-channel home theatre or high quality distributed audio 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: 
•      Stereo or home theatre system where the location of speakers relative to 
each other is important.
•    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.
Aego Custom Install speakers are NOT magnetically shielded. Magnetically sensitive 
equipment or media should be kept at least  m away.

1. In-wall Speaker Positioning 
						

							
Page 2
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 to 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.
Mounting Clearances
Clearance depth is required behind the speaker aperture and clearance space 
is required on the inside surface of the wall on the longer sides of the speaker 
aperture. 
The minimum depth clearance behind the speaker aperture, measured from the 
outer surface of the wall, is  02mm (4 inches). The minimum 
space along the longer 
sides of the speaker aperture is 38mm (.5 inches). Only nominal clearance is 
required on the short sides of the speaker aperture - the speaker frame can butt-up 
against internal joists if necessary.
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.

Stereo and Home Theatre Speaker Positioning
If a pair of speakers is to be used  in a conventional 
stereo audio system, or for the front channels in a 
home theatre system, they should be positioned 
approximately as follows:
•  Between 2.0 and 3.0 metres apart (either side of the   
  screen in home theatre systems).
 
•  In portrait orientation.
 
•  Clear of corners.
 
•  Slightly above, listening head-height (and around   
  screen height in home theatre systems).
If a speaker is to be used for the centre channel 
in a home theatre system it should be positioned 
approximately as follows:
•   Directly above or below the display screen in 
portrait orientation.
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. 
 
•  At least 0.5m above listening head height.
 
•  In portrait orientation.
Diagram One illustrates general home-theatre in-wall 
speaker positioning.
Don’t worry if, thanks to the architecture 
or layout of your room, it is not practical 
to follow each requirement exactly. The 
most important thing is to consider the 
practical option and identify the one that 
is likely to work best.
Utility Speaker Positioning
If your Aego Custom Install 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 and mounted at or just above head 
height.

Aego Custom Install In-ceiling speakers are intended to be used in high quality 
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

•    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.
Aego Custom Install speakers are NOT magnetically shielded. Magnetically sensitive 
equipment or media should be kept at least  m away.
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 Aego 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.

“replaced” by the sound from the next nearest speaker. The overall volume should 
be relatively constant.
Mounting Clearances
Clearance depth is required behind the speaker aperture 
and clearance space is required on the inside surface of 
the ceiling around the speaker aperture. 
The minimum depth clearance behind the speaker 
aperture, measured from the outer surface of the ceiling, 
is 02mm to  53mm (4 to 6 inches) depending on the 
specific speaker model. The minimum space around the 
speaker aperture is 38mm (.5 inches).
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.

Connecting Aego Custom Install speakers to an amplifier is fundamentally a simple 
process. However, there are some choices to be made and issues to consider 
concerning speaker cable type. Each speaker is fitted with spring connection 
terminals designed to accept stripped wires.
Two terminals are fitted to Aego Custom Install In-wall and In-ceiling speakers: 
negative and positive. Identification of the terminals is illustrated in Diagram Two 
below.
To connect the speakers simply push the terminal lever down, insert the stripped 
wire into the hole and release the lever.
Take care not to connect any negative and positive terminals together and “short-
circuit” the amplifier. Always make connections with the amplifier switched off.
Connection Polarity.
It is important to ensure that each speaker is connected with the same polarity. 
Positive speaker terminals should always be connected back to amplifier positive 
terminals, and negative speaker terminals connected back to amplifier negative 
terminals. Performance will be degraded if connections are made with incorrect 
polarity.
Cable Choice.
Choice of speaker cable type will be influenced by the 
characteristics of other components in your system and 
your dealer or distributor will be able to advise. There 
are however some simple guidelines to consider:
  •    Cable runs to each speaker should be kept as 
short as possible. 
•    Short cable runs are especially important if the 
cable is of relatively small cross-sectional-area. 
•    If the cable is advertised as “directional” care 
should be taken to ensure that its orientation is as 
recommended.
Amplifiers
Aego Custom Install speakers are relatively high 
sensitivity speakers that do not require generously 
rated power amplifiers for adequate volume levels to be 
achieved in an average listening room. A minimum of 
25 and maximum of  00 Watts into 8 Ohms per channel 
is recommended. They also offer a relatively easy load 
to the amplifier and do not make unusually heavy 
demands on its power delivery.  
No overload protection systems are fitted to Aego 
Custom Install speakers so it is possible to cause 
damage through over-driving. Such damage can occur 
regardless of the power rating of the driving amplifier 
and is not covered by any warranty. If ever the sound at 
high volumes becomes distorted your speakers are at 
risk of damage. In such circumstances the volume must 
be reduced.

Do not paint grilles while they are fitted and take care that a significant number of 
grille perforations do not become blocked. Remove the logo badge and the “scrim” 
cloth attached to the back of the grilles (do not paint the back of the grille). Use the 
wax paper sheet to protect the scrim. When the paint is dry replace the scrim cloth 
by pressing it in to place on the back of the grille. Fit (or refit) the grille by aligning it 
with its retaining groove and gently pushing-in from its edges. The logo badge can 
be repositioned to suit.

Once you have decided on the positions of each 
speaker and established the location of joists, cables or 
pipes, use the Cut-out Template included in the pack 
to mark out the speaker apertures (remember that the 
speaker frame is bigger than the marked hole). Take 
care when installing the speakers not to touch the 
driver units.
To cut and prepare speaker apertures proceed as 
follows:
•     Drill a hole at the centre and check using a piece of 
wire that the appropriate clearances are available.
•      Mark the cut-line and cut the aperture along the 
line using the appropriate tools. Clear any loose 
debris away
•      Run the speaker cable you have chosen to use and 
prepare the ends for connection to the speaker.
Acoustic performance can be improved by placing 
insulation material in the cavity but leaving clear the 
area directly behind the speaker.
Painting
Aego Custom Install speaker outer frames and grilles 
may be painted using matt emulsion paint. No primer 
coat is necessary. Use two light coats applied with 
brush or spray.  Use the supplied painting mask when 
painting the outer frame.

IR Control
An Infra-Red receiver access hole is provided on the 
front panel of Aego Custom Install In-Wall speakers 
behind the grille. As supplied, the access hole is closed-
off with a plug. If an IR receiver is to be used, remove the 
plug by gently pushing it from the back.
Installing a Speaker
With the aperture cut and prepared the speaker can be 
fixed in the wall or ceiling. Remember to connect the 
speaker cable before installing the speaker.

Before using your Aego Custom Install speakers for the first time make one 
final check of the cables and connections. If all appears well begin listening at 
a relatively low level to confirm that the system is operating as expected. Only 
increase the volume if you are happy with the sound at low levels. If you are 
unhappy, turn the system off and re-check all the cables and connections.
The speakers may take a little time to reach normal operating temperatures and to 
“run-in”. Your ears too will take some time to adjust to the new sound so revisiting 
the speaker installation is best left for a few days.

If the speaker grille is fitted (they are shipped with grilles 
removed) remove it by pulling gently from its edges. 
Also remove the wax paper sheet and paint mask from 
inside the grille. To insert and secure a speaker in a wall 
or ceiling proceed as described following. Diagrams 
Three and Four illustrate in-ceiling and in-wall speakers 
offered-up to an appropriate aperture.
•  Ensuring that the fixing clamps are lying flush 
against the sides of the speaker, offer the speaker up to 
the aperture and hold it in place so that any clearance is 
distributed approximately equally around the aperture. 
• Using a No. 2 Pozidriv screwdriver via the access 
holes tighten the four or six fixing clamps in turn. As the screws begin to tighten 
the fixing clamps will turn outwards and  begin to make contact with the rear of 
the wall or ceiling. Tighten just enough to pull the speaker solidly and securely in 
contact around its entire perimeter. Do not over-tighten and Do not use a power 
driver or drill.
•   Fit the grille by aligning it with its retaining groove and gently pushing from 
its edges. The logo badge is removable and can be repositioned to suit.
