APU2 / APU-RS8
Your AIWX speaker must be used with the supplied APU protection device. AIWXn models
should be used with an APU2 or APU-RS8 or Amina approved active device in commercial
systems. Please refer to the detailed instructions supplied with the APU2 and APU-RS8 for
connection advice.
AIWX Audio Characteristics
Your AIWX speaker 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 characteristic
has the benefit of allowing positioning to be far less critical than with conventional
speakers. Additionally, just like the acoustic musical instrument, the AIWX has excellent
room filling abilities.
Wall or Ceiling Placement
The AIWX is suitable for both wall and ceiling installations. When the most uniform audio
coverage in a room is required it is best to space the speakers evenly in the ceiling.
However if the room has a height greater than 6m (19’) Amina suggests installing the
speakers in the walls at a height of around 1.8m (6’).
In dedicated listening rooms where AIWX speakers are used in stereo or multi channel
systems, position in walls so that the centre point of the AIWX is approximately 1 – 1.8m
(3 - 6‘) from the floor, this will give excellent results. Don’t worry if this is not possible to
achieve as the audio characteristics of the AIWX makes exact positioning according to
stereo/5.1/7.1 conventions far less critical.
Speaker Orientation
Amina have designed the AIWX to be installed either in portrait or landscape orientations
and there is no audible benefit in positioning them in one orientation over the other.
System Requirements
From a system compatability point of view your AIWX can be treated like any conventional
8 Ohm speaker. Amina recommend you use a good quality amplifier so as to avoid driving
them with a distorted signal which may permanently damage the speaker. Amina also
recommend you connect the AIWX to your amplifier with at least 16AWG OFC cable
(14AWG for long runs) to avoid any chance of reduced efficiency and audio bandwidth.
For 2.1/5.1 and 7.1 systems, always set the amplifier to divert frequencies below 120Hz to the
subwoofer. This will improve the overall sound quality and power handling of the system.
(APU2 and APU-RS8 should still be used).
AIWX speakers are sonically revealing and will highlight any shortcomings in the source or
amplifier.
Sound Transmission
As with any speaker designed to be fixed to a structure within a wall or ceiling, careful
consideration should be given to sound transmission into adjacent rooms or properties.
We recommend specialist advice is taken if sound transmission into adjacent rooms
needs to be minimised. See the Amina specifiers guide for information on reducing sound
transmission as a starting point.
100/70V Option
For multi-speaker commercial and industrial installations, AIWXn speakers can be supplied
with 100/70V line transformers fitted.
