3. Installation
The Aegis Neo Subwoofer is intended to be used in
either stereo audio music systems or multi-channel
audio-visual (home theatre) systems. Although it is
intended primarily to partner other products in the
Aegis Neo range it may also be used successfully with
alternative loudspeakers.
The Aegis Neo Subwoofer should be fitted with either
floor spikes or rubber feet. Floor spikes offer the
highest potential performance and should be fitted
if the subwoofer is to be placed on a carpeted floor.
If spikes are inappropriate for your floor covering,
metal protection pads, coins for example, may be used
between the spike and the floor.
Note: Damage to the drive unit may result if the Aegis
Neo Subwoofer is placed face down on the floor.
The rubber feet or M8 floor spikes and lock-nuts
should be fitted to the underside of the subwoofer
once it has been moved near its final location.
Carefully lay the subwoofer on its side to gain access
to the tapped holes in the underside. If the rubber feet
are to be used, simply screw them into the tapped
holes and return the subwoofer to upright. If floor
spikes are to be used, screw a spike and lock-nut into
each hole leaving a length of spike extending beyond
the lock-nut so that when the subwoofer is upright the
lock-nuts will “float” just above the floor covering.
1. Introduction
2. Handling
Tighten three of the lock-nuts with a 13mm spanner leaving one lock-nut finger-
tight to aid adjustment once the subwoofer is upright in its final position. Once the
final position has been established adjust the length of the loose spike so that the
subwoofer is vertical and does not rock. If the floor is particularly uneven it may be
necessary to loosen one of the tightened spikes to ensure that the subwoofer can
be levelled.
Finally, tighten all loose lock-nuts. It may be necessary to re-adjust to minimise rock
once the subwoofer has settled on the floor. Take care when installing floor spikes.
They are sharp and can cause injury or pierce electrical cables.
The Aegis Neo Subwoofer is not magnetically shielded and may cause picture
distortion if located too close to a CRT screen. Contact your dealer, installer or
Acoustic Energy for advice.
4. 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 One over the page illustrates an idealised general home theatre speaker
layout.
If you are already familiar with the characteristics of your room, and the way
speakers perform in it, you may already have a good feel for where to position your
Aegis Neo Subwoofer. However, installing any new component provides a good
opportunity to review an existing set-up and perhaps make improvements.
In principle there is great freedom of position of a sub-woofer in a listening room. In
practice, however, the performance will be fundamentally influenced by the room
and position. Small changes of location, or of the acoustic character of items in the
immediate vicinity of the subwoofer, can significantly influence its performance.
Initially choose a site for the Aegis Neo Subwoofer along one of the walls of the
listening room well away, but not equidistant, from the corners. It is not necessary
that the subwoofer be positioned along the same wall as the main speakers. Chose
a solid wall (rather than a partition) and keep the subwoofer clear of any large
resonant objects - furniture panels, heating radiators, etc.
Don’t worry if, thanks to the architecture or layout of your room, it is not practical to
follow these guidelines exactly. The most important thing is to experiment with the
different options that are practical and find the best one.
Once your Aegis Neo Subwoofer is 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, moving the Aegis Neo Subwoofer towards a room corner
will increase the level of low bass. This gain may however be at the expense of bass
definition and consistency over the listening area.
