6. Neo One and Three Positioning 7. Neo Centre Positioning
The position of the speakers in a home theatre
installation will have great influence over its
performance. It is worth spending some time
experimenting both with the finer points of speaker
positioning, as well as the larger scale issues of room
layout. Diagram Two illustrates an idealised general
home theatre speaker layout.
If you are already familiar with the characteristics
of your home theatre room, and the way speakers
perform in it, you may already have a good feel for
where to position your Aegis Neo Centre. However,
installing any new speaker component provides a good
opportunity to review an existing set-up and perhaps
make improvements.
The position requirements for an Aegis Neo Centre are as follows:
• Between 0.05 and 1.0 metres from the rear wall.
• Generally in-line with the display screen.
• Directly above or below the display screen.
Don’t worry if, thanks to the architecture or layout of your room, it is not practical
to follow each requirement or the layout diagram exactly. The most important
thing is to experiment with the different options that are practical and find the one
that works best. Aegis Neos are magnetically shielded and can be used in close
proximity to CRT screens.
Once your Aegis Neo Centre is connected (see Section 8) and working, and
you begin to become familiar with its performance, it is likely to be worthwhile
experimenting a little more with its positioning. For example, reducing the distance
between the speaker and the rear wall will increase the level of bass and low
midrange making the speaker sound warmer. The warmth however is likely to be
gained at the expense of some mid-range clarity.

Diagram Two
Each Aegis Neo is fitted with a pair of binding-post
terminals. The terminals can accept either stripped
wires, spade connectors, or 4mm plugs. Each of these
termination methods is potentially equally effective
and the choice is likely to be influenced by the type
of speaker cable used. Your dealer, distributor or cable
manufacturer will be able to offer advice.
To connect the speakers, simply connect the speaker
cable to the terminals ensuring correct connection
polarity as described below. Take care when
connecting cables not to touch the negative and
positive terminals together and “short-circuit” the
amplifier. Make connections with the amplifier off.
Connection Polarity.
It is important when connecting speakers to ensure
that each terminal is connected with the correct
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 cable type will be influenced by the
characteristics of other components in your hi-fi system
and your dealer or distributor will be able to advise.
8. Connecting
There are however 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.
