Welcome to Aego-T. Perhaps more than any 
other audio-visual 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 Aego-T 
system performs optimally. Should you have any 
questions not covered here we are happy to try 
and answer them either by telephone or email. 
Contact information can be found in Section 11.
Following this introduction, the Manual is divided 
into sections covering Handling, Installation 
and Positioning, Wall Brackets, Connections 
and Amplifiers, Controls and System Setup, 
Specifications, Warranty and Contact Information. 
We suggest that you read at least the first six 
sections carefully before installing and using your 
Aego-T system. We would also draw your attention 
to the Important Safety Instructions on this page.
Finally, please enjoy your Aego-T system, but 
remember it is capable of generating high volume 
levels of low frequency sound, so please also be 
considerate of your neighbours.
Aego-T comprises relatively delicate precision 
engineered items that can be damaged by 
inappropriate handling. They are also heavy and 
in the case of the subwoofer large. Please take 
great care therefore when unpacking, moving and 
installing them. Please take care when unpacking 
or moving the speakers not to touch any of the 
drivers beneath the fabric grilles. Damage to a 
driver will at best degrade performance and at 
worst result in failure.
The enclosure surfaces should also be handled 
sympathetically. Any cleaning should only require a 
soft cloth, slightly dampened if necessary. Be wary 
of using any polishes or solvent based cleaning 
agents.
The packaging should be retained for future use if 
possible or appropriately re-cycled.

Aego-T is a satellite and subwoofer loudspeaker 
system designed to be used in domestic audio and 
audio-visual (home theatre) systems. It comprises 
a compact passive satellite speaker and an active 
(powered) subwoofer. The satellite speakers may 
be used either placed on furniture or wall-mounted 
using the included brackets. The subwoofer should 
be used placed on the floor. Use of the satellite 
wall-brackets is described in Section 4.
Aego-T satellites need to be connected to an 
external power amplifier - this might be a 
conventional hi-fi stereo amplifier or a multi-
channel home theatre amplifier/processor. In 
either case it should have the facility to provide an 
appropriate line-level subwoofer output signal.
Aego-T systems comprising between two and 
seven satellites speakers may be installed with 
one subwoofer. Systems including more than 
seven satellite speakers should include multiple 
subwoofers.
To ensure that programme material is heard as 
intended it is important that each Aego-T element 
is located appropriately. For Aego-T systems 
comprising from two to seven satellites locate the 
speakers as described in the following paragraphs 
and refer to Diagram One over the page. Don’t 
worry if it is not practical to follow the diagram 
exactly but experiment with the options that 
are practical in order to find the one that works 
best. Once your Aego-T system is connected 
and working (see Section 6), and you begin to 
become familiar with its performance, it is likely to 
be worthwhile experimenting a little further with 
positioning.
Two satellites only (Stereo System)
A stereo system is most likely to be used for 
conventional stereo audio only rather than audio-
visual programme. In this case the satellites should 
be located near or on the wall facing the listening 
position and; 
•     Between 0.05 and 0.5 metres from the rear 
wall.
•     1.0 metres from side walls and clear of corners.
•    Between 2.0 and 3.5 metres apart.
•     Equidistant from and angled towards the 
listening position.
The location of the subwoofer is less critical but it should be placed a similar 
distance away from the listening position as the satellites. Try to avoid a 
location for the subwoofer exactly halfway along the length or width of the 
room.
Three satellites, one subwoofer (3.1 System)
A 3.1 system is most likely to be used for audio-visual (home theatre) 
programme. In this case the satellites should be located one either side of the 
screen, and one centrally either directly above or below the screen. The basic 
positioning guidelines for the left and right satellites are the same as for the 
2.1 system described above. The central satellite may be positioned either on 
the wall, on a furniture unit or a screen stand.
The location of the subwoofer is less critical but it should be placed a similar 
distance away from the listening position as the satellites. Try to avoid a 
location for the subwoofer exactly halfway along the length or width of the 
room.
Five satellites, one subwoofer (5.1 System)
A 5.1 system is most likely to be used for audio-visual (home theatre) 
programme. In this case, three satellites should be located in front of listening 
position, one either side of the screen and one centrally, and two “surround” 
satellites located just behind the listening position one either side of the room. 
The front central satellite should be located either directly above or below the 
screen. The surround satellites may be located well above head height. The 
basic positioning guidelines for the left and right satellites are the same as for 
the 2.1 system described earlier. The central satellite may be positioned either 
on the wall, on a furniture unit or a screen stand.
The location of the subwoofer is less critical but it should be placed a similar 
distance away from the listening position as the satellites. Try to avoid a 
location for the subwoofer exactly halfway along the length or width of the 
room.
Seven satellites, one subwoofer (7.1 System)
A 7.1 system is most likely to be used for audio-visual (home theatre) 
programme. In this case, three satellites should be located in front of listening 
position, one either side of the screen and one centrally, two “surround” 
satellites just behind the listening position one either side of the room, and a 
two further surround satellites directly behind the listening position. The front 
central satellite should be located either directly above or below the screen. 
The surround satellites may be located well above head height. The basic 
positioning guidelines for the left and right satellites are the same as for the 
2.1 system described earlier. The central satellite may be positioned either on 
the wall, on a furniture unit or a screen stand.
The location of the subwoofer is less critical but it should be placed a similar 
distance away from the listening position as the satellites. Try to avoid a 
location for the subwoofer exactly halfway along the length or width of the 
room.

An adjustable wall bracket is supplied with each Aego-T satellite. To install the 
wall brackets proceed as described below and illustrated in Diagram Two.
Note: It is very important that wall brackets are fitted securely. If you 
are in any doubt about your ability to achieve a secure installation you 
should seek professional advice and assistance.
The wall bracket is held to the wall via two screws inserted through elongated 
holes in the bracket’s wall plate. No.8 (4.5mm) round-head, rather than 
countersunk-head, screws should be used. The length of screw necessary and 
type of wall fitting required will depend on  the construction and condition 
of the wall. If in any doubt seek professional advice.
Once the wall mounting locations for Aego-T satellites have been chosen use 
the wall brackets themselves as templates to mark the screw positions. Loosen 
the bracket adjustment screw using the allen key supplied and angle the 
mounting post away from the wall plate to gain easier access to the holes.
With the screw holes drilled and appropriate wall fittings inserted, securely 
screw the brackets to the wall and return the mounting post to the vertical.

Note: The elongated bracket holes enable some 
adjustment for vertical alignment.
To attach an Aego-T satellite to a wall bracket 
simply place the satellite above the bracket and 
slide it onto the mounting post.
Note: Connecting cables to Aego-T satellites is best 
done before they are mounted on wall brackets. See 
Section 5.
Loosen the bracket adjustment screw to adjust the 
satellites vertical angle. Turn the satellite on the 
mounting post to adjust its lateral orientation.

Satellite Connection
Connecting Aego-T satellites to an audio amplifier 
or audio-visual processor is fundamentally a simple 
process. If only two satellites are to be connected, 
identify the left and right speaker output terminals 
on the amplifier connection panel and connect one 
satellite to each. If three or more Aego-T satellites 
are to be used in a multi-channel home-theatre 
system with an audio-visual processor/amplifier, 
identify the appropriate output terminal for each 
channel (front left, centre, front right, etc) and 
connect a satellite to each.
Aego-T satellites are fitted with a pair of binding-
post terminals intended to be used with stripped 
wires. Insert a stripped wire end through the cross-
hole of each terminal and tighten the terminal 
sleeve. Take care when connecting cables not to 
touch the negative and positive terminals together. 
Make connections with all system electronics 
switched off.
It is important when connecting Aego-T satellites 
to ensure that each 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 
seriously degraded if connections are made with 
incorrect polarity.
Choice of cable type to connect Aego-T satellites 
will be influenced by the characteristics of other 
components in your hi-fi system and your dealer or 
distributor will be able to advise. Even so, there are 
some simple guidelines to consider:
•  Cable runs to each speaker should be kept as 
short as possible consistent with each being 
of equal length. 
•  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.
Aego-T Satellite Amplifiers
The Aego-T satellite is a relatively high sensitivity speaker that does not 
require a generously rated power amplifier for adequate volume levels to be 
achieved in an average listening room. A minimum of 25 and maximum of 
100 Watts into 8 Ohms per channel is recommended. Aego-T satellites 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-T satellites so it is possible 
to cause damage through over-driving. Such damage can occur whatever the 
power rating of the 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.
Subwoofer Connection
The Aego-T subwoofer requires connection both to mains power and an 
appropriate subwoofer line-level output signal. The connection sockets are 
located on the back of the subwoofer. Leave the subwoofer switched-off at 
the mains until all connections are made and ensure that the subwoofer level 
control, also located on the connection panel is turned fully anti-clockwise.
Connect the subwoofer to the audio-visual processor subwoofer output using 
an appropriate RCA Phono connection cable. Ensure that the cable is of good 
quality.
After checking that the mains voltage selector on the subwoofer connection 
panel is set correctly, connect the subwoofer via its IEC mains input to a mains 
wall socket. Use only the mains cable supplied with the subwoofer.

Subwoofer Controls
Accompanying the mains and signal input sockets on the subwoofer 
connection panel are a level control, an auto power switch and a phase 
reversal switch. Their function and use is described in the following 
paragraphs.
Subwoofer Level
The level control adjusts the volume of the subwoofer relative to the satellites. 
Begin with the level control set to around 50%. Detailed subwoofer level 
adjustment guidelines can be found below.
Subwoofer Phase
The phase switch reverses the subwoofer acoustic polarity. With the switch 
set to 0° the subwoofer output is in phase with the satellites. With the switch 
set to 180° the subwoofer output is out of phase with the satellites. Reversing 
the subwoofer phase can help optimise the sound of Aego-T satellite and 
subwoofer systems. Further subwoofer phase advice can be found below.
Subwoofer Auto Power
The subwoofer mains power switch incorporates an automatic switch-on/
off function. With the switch set to “Auto” the subwoofer will switch on 
automatically when an audio signal is present. It will switch off again when 
no signal has been present for around 10 minutes. With “on” selected the 
subwoofer remains switched-on permanently.
System Setup
Before listening to your Aego-T system make one final check of the cables and 
connections. If all appears well begin listening at a relatively low volume to 
confirm that the system is operating as expected. Only increase the volume 
if you are happy that the sound at low volume is fundamentally as expected. 
If you are unhappy, turn the system off and re-check all the cables and 
connections.
Aego-T systems 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 it is unwise therefore to make rapid judgements about the performance of 
the system.
The most important aspect of Aego-T system setup is the integration of the 
satellites and subwoofer. Assuming the locations chosen for the satellites are 
satisfactory, adjusting the subwoofer’s location in the room, its volume level 
and phase, and the subwoofer filter frequency selected on the audio-visual 
processor should enable a good end result to be achieved.
Select a few short examples of familiar programme material - both movie and 
music - to use while adjusting the setup. Listen also from a variety of different 
positions in the room. Check for balance and consistency of sound - neither 
too much nor too little bass across the range of programme material and 
listening positions. Experimentation and careful listening is the key to finding 
a good subwoofer setup.
Subwoofer Filter Frequency
The Aego-T satellite and subwoofer are designed to 
work together with a crossover frequency of 80Hz 
so the first setup parameter to adjust is to set the 
audio-visual processor’s subwoofer filter frequency 
to this value. As you adjust other parameters you 
may find that moving the filter frequency a little, 
say 10Hz either way, is beneficial. Adjust other 
aspects of the setup, particularly subwoofer phase,  
before selecting a filter frequency higher than 90Hz 
or lower than 70Hz. 
Note: Despite their small size, Aego-T satellites 
can handle and reproduce full range audio, so the 
audio-visual processor should be set to treat them 
as “large” speakers.
Sub-woofer Volume
Setting the subwoofer volume is important in terms 
of both overall system balance and the demands 
of different types of programme material. You 
may find that material with an emphasis on music 
works better with a lower subwoofer volume than 
movie material with an emphasis on “effects”. 
Finding a compromise between the two is a matter 
of subwoofer volume adjustment in parallel with 
adjusting its position in the room.
Sub-woofer Location
Broadly speaking, the closer a subwoofer is to the 
walls of the room (assuming they are solid brick 
walls) the more bass it will generate in the room 
(and the lower its volume need be set). Moving 
the subwoofer closer to the walls however will also 
tend to reduce the consistency subwoofer volume 
over the listening room (a corner location being 
the worst in this respect). Positions closer to the 
wall with also tend to change the character of the 
bass produced by the subwoofer - it will emphasise 
the very lowest signals more. This change in bass 
character with location is the variable that enables 
a good compromise position for the subwoofer to 
be found.
Sub-woofer Phase
Switching the subwoofer phase should be left to 
last. If a good subwoofer position is proving difficult 
to find, try again with the phase reversed.
