APU750
Your Evolution Series AIW750E speaker must be used with the supplied APU750
crossover/protection device. Please refer to the instructions supplied with the APU750
for further details.
Installation Backboxes
The AIW750E has been designed for optimum sound quality when used in the Amina
Backboxes. We recommend that they are used wherever possible in a cavity type
installation. If our basic fixing block kit is used you may find that the low/mid
frequencies are reproduced less accurately and a possibility of increased sound
transmission between rooms. Any effect will be very much installation specific.
When installed into solid walls or ceilings using the Amina BackboxSW, you may find
that your AIW750E reproduces slightly less low frequency output compared to a
BackboxCV345 installation. Also, depending on the building construction there may be
significant mechanical sound transmission into adjacent rooms/properties (see inside
front cover).
AIW750E Audio Characteristics
The AIW750E generates sound in a similar way to an acoustic musical instrument. The
speaker’s front face is effectively the “musical” soundboard and the sound waves
generated from it are diffuse and are dispersed over a very wide angle. This means that
loudspeaker positioning is far less critical than with conventional speakers. Additionally,
just like the acoustic musical instrument, the AIW750E has excellent room filling
abilities.
The AIW750E is a planar device and this feature is further enhanced when it is flush
mounted into your wall or ceiling. Being planar (or flat) means that the audio’s arrival
time to the listener is the same for all frequencies, i.e. there is very little phase
distortion. Therefore the AIW750E (and other planar devices such as electrostatic
loudspeakers) can reproduce subtle nuances on a recording with incredible accuracy.
In addition to the above characteristics, the radiating surface of an AIW750E is very
stiff and undergoes very small amounts of movement in order to generate high sound
pressure levels. This means that the AIW750E is inherently “fast” making it a highly
articulate loudspeaker.
Wall or Ceiling Placement
The AIW750E is suitable for both wall and ceiling installations. When the most uniform
audio coverage in a room is required, space the speakers evenly in the ceiling. However
if the room has a height greater than 6m (19’) Amina suggests installing them in the
walls at a height of around 1.8m (6’).
In dedicated listening rooms where AIW750E speakers are used in stereo or multi
channel systems, position them in the walls so that the centre point of the AIW750E’s
HF panel is approximately 1 – 1.8m (3.5 - 6‘) from the floor. This will give excellent results,
but don’t worry if this is not possible to achieve in your room as the audio
characteristics of the AIW750E make exact positioning according to stereo/5.1/7.1
conventions far less critical.
