Boundary Loading
It is possible to increase the low frequency output of the AIW750E by positioning them
close (50mm - 150mm) to the corners of a room. The recommended setup on the
previous page show the LF panel in both cases being either close to the floor or
ceiling. The AIW750E has been optimised for this proximity to boundaries and will
reproduce slightly less bass if positioned well away from room boundaries.
System Requirements
From a system compatibility point of view your AIW750E (and its accompanying
APU750 crossover/protection unit) can be treated like any conventional 4 Ohm
loudspeaker. Amina recommend 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 AIW750E to your amplifier with at least 16AWG oxygen free (OFC) cable or
alternatively 14AWG for long runs to avoid any chance of reduced efficiency and audio
bandwidth.
For 2.1, 5.1 and 7.1 systems use the amplifier’s crossover settings to divert frequencies
below 60Hz to your subwoofer. This will improve the dynamic range and power handling
of the system. (APU750 MUST still be used).
IMPORTANT: the AIW750E is 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 AIW750E.
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 Specifier’s guide for information on reducing
sound transmission as a starting point or contact Amina directly for advice.
100/70V Option
The AIW750E is not compatible with 100/70V line audio systems.
