rectangular room, it is often the case that use
against the longer wall will produce better
results. This is because the long wall position
tends to result in less prominent reflections from
the side walls of the room. However, whether
used against the long or short wall, it is
important that each loudspeaker of the pair is
located in a similar acoustic environment
(different environments would be, say, a
curtained area and a solid wall). Similarly, the
acoustic character of the side walls of the room
in the area where the main reflection between
speakers and listening position will occur should
also be similar. Diagram One illustrates a typical
layout with some of these issues highlighted.
Once the AE1s are connected (see the following
section) and working, and you begin to become
familiar with their performance, it is likely to be
worthwhile experimenting a little more with
their positioning.
The AE1 is a relatively low sensitivity speaker and
so requires a generously rated power amplifier if
relatively high volume levels are to be
comfortably achieved in an average listening
room. A minimum of 50 and maximum of 200
Watts into 8 Ohms per channel is
recommended. AE1s offer a relatively easy load
to the amplifier and do not make unusually
heavy demands on its current delivery.
No overload protection systems are fitted to the
AE1 so it is possible to cause damage through
overdriving. Such damage can occur whatever
the power rating of the amplifier and is not
covered by any guarantee. If ever the sound at
high volumes becomes distorted your AE1s are
at risk of damage. In such circumstances the
volume must be reduced.
Reducing the distance between the AE1s and the rear wall will increase
the level of bass and low midrange making the speakers sound warmer.
The warmth however is likely to be gained at the expense of some mid-
range clarity and stereo image focus and depth. Increasing the toe-in
angle of the speakers may regain some image focus but again this is
lightly to be at a cost of image width and openness. Learning through
experimentation how AE1s behave in your room will help you find the
optimum solution.
