Speaker Orientation
The Evolution Series can be installed either in portrait or landscape orientations. Typically
the spacing between wall joists will dictate portrait orientation and Amina have optimised
the dispersion characteristics for this setup. Therefore when installing into walls Amina
suggest portrait orientation for best sound quality.
For non-critical listening in ceiling installations the orientation of the speaker is not crucial.
For critical listening in ceilings, e.g. a 5.1 surround system, ensure that the orientation of all
speakers are the same relative to the main listening position and position the top of the
speaker closer to the wall boundary.
Boundary Loading
It is possible to increase the low frequency output of Evolution Series speakers by
positioning them close (50mm - 150mm) to the corners of a room. This can be useful when
no additional bass enhancement unit (e.g.. ALF40) or subwoofer (eg ALF80) is used.
System Requirements
From a system compatibility point of view your Evolution Series (and it’s accompanying
APU protection unit) can be treated like any conventional 4 - 8 Ohm loudspeaker. Amina
recommends you use a good quality amplifier so as to avoid driving them with high levels
of distortion, which at best, will provide poor sound quality and at worst may permanently
damage the loudspeaker. Amina also recommend you connect the Evolution Series to your
amplifier with at least 16AWG OFC (oxygen free) 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 use the amplifier’s crossover settings to divert
frequencies below 100Hz to your subwoofer. This will improve the dynamic range and
power handling of the system. (APU devices should still be used).
IMPORTANT: Evolution Series speakers are highly revealing of any shortcomings in the
source or amplifier. Please be aware that some low cost zone amplifiers will produce high
amounts of distortion well within their operating range and this will be ruthlessly revealed
by a speaker such as the Evolution Series.
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. Please talk to the Amina technical team for advice on reducing sound
transmission as a starting point.
100/70V Option
For multi-speaker commercial installations, AIW150En, AIW150En-S200, AIW350En,
AIW350En-S200 & AIW550En loudspeakers can be supplied with 100V or 70V line
transformers fitted. In these systems an active high-pass filter must be installed - 24dB/
octave at 120Hz minimum attenuation. Power ratings of 5W, 10W, 20W or 40W are
available.
