Caution: Read before installing this product
To ensure optimal performance, please
read this guide carefully and keep in a
safe place for future reference.
Install this product in a cool, dry, clean
place - away from direct sunlight and
heat sources, vibration, chemical fumes,
dust and moisture (steam).
Do not expose this product to sudden
temperature changes or locate it in an
environment with high humidity. This is
to prevent condensation forming inside
which may cause damage to the
product.
Do not clean this product with chemical
solvents as this may damage the finish.
Use a clean, dry or damp cloth.
Ensure that all installation mounting
surfaces are able to support the weight
of the product.
After installation, avoid pushing on the
wall or ceiling surface immediately in
front of the speaker. Excessive
excursion, whilst unlikely to damage the
speaker, will undoubtedly crack the
plaster around its perimeter.
Do not attempt to modify or repair the
product. Contact your distributor or
manufacturer if a fault should occur.
The rear of the product should not be
subject to chemical cleaning and should
not be painted in any way.

ENVIRONMENTAL:
Before installing, ensure that the building is environmentall y sealed, de-humidified and at
a stable temperature of at least 16 degrees centigrade (61 degrees fahrenheit).
This product should not be used with single thick coat plaster solutions or with other
finshing methods that take days (rather than hours) to dry out.
Please be aware that when this product is directly fitted into a solid wall structure (e.g
when using the solid wall backbox) vibrational energy is inevitably transferred into the
solid wall structure. This energy can travel for some considerable distance up, down and
along the structure. It is therefore recommended the product be fitted within acoustically
insulated stud walls or ceiling sections where possible. The use of the product directly
embedded in solid walls is not recommended in multi occupancy buildings.
WARNING:
No attempt should be made to install this product within existing building structures
unless you are certain that no electric cables, water pipes, gas pipes or supporting joists
will be cut through.

Preparing the wall/ceiling and xing the product
Locate joist/stud work
When you have chosen your speaker
locations, before cutting a hole in the
plasterboard it is important that you
locate the position of the joists/studs.
Ensure the spacing between them is at
least 350mm (133/4”) for a portrait ori-
Create 455mm x 350mm aperture for
LF panel
Using a sharp knife or pad saw, cut an
aperture with dimensions 455mm x
350mm (18” x 14”) in your plasterboard
wall or ceiling. Ensure aperture is
created between supporting joists or
stud work.
We strongly advise that joists are not
cut to make space for the product. Any
activity of this sort may well influence
the structural integrity of your property.
Important: Double check the size of the
aperture is 455mm x 350mm (18” x 14”)
as this is important further on into the
installation process.
Create 455 x 205mm aperture for HF
panel by following the same
procedure.

Installing the BackboxCV345 & CV200
04
Locate cable and position backbox
Pull the speaker cable through the rubber
grommet in the top side of the backbox
and ensure speaker cables are pulled
through with a manageable length
available. Apply the Backbox through the
hole at an angle until the end cheeks rest
against the back side of the
plasterboard.
Use the fold out tabs at either end of the
backbox to help support it in position
before securing it to the plasterboard.
A minimum 75mm/3” cavity depth is
required to fit BackboxCV345 & Backbox-
CV200
IMPORTANT:
Allow at least 80mm gap between
plasterboard cut-outs to accomodate
both HF and LF loudspeaker panels when
positioned one above the other.
Fix backbox
Using a minimum of 8 drywall screws
(4 at each end) fix the backbox by
screwing through the plasterboard
and self tapping into the flat end
cheek areas at each end of the
backbox. When positioned correctly,
the backbox’s speaker mounting lip
with soft foam surface should be
visible along all four sides of the
aperture. Connect the speaker cable
by using a high quality crimping tool.

Secure the speaker
With the speaker resting on the
backbox mounting lip, use screws
provided to secure the speaker onto the
backbox by self tapping into the
mounting lip, through the pilot holes
provided at each corner.
Ensure the speaker face is flush with the
front of the plasterboard and that
everything is firmly held in position.
Shims may be necessary.
Amina backboxes (BackboxCV345 and
CV200) are designed for 12.5mm (1/2”)
plasterboard.
Shims can be supplied to adapt the
backbox for different plasterboard
thicknesses. Contact your supplier
when ordering.
IMPORTANT: at this point you should
perform the first set of speaker tests to
check for correct cabling and to
identify any sources of buzz and rattle
in the building construction.

Plastering and decorating
06
Apply PVA
Using a brush or foam roller, apply a
thin coat of neat PVA (wood glue) to the
entire speaker panel surface, this will
assure proper adhesion between the
panel surface and the plaster coating.
Important: Amina recommends you
leave the 1 coat of PVA to completely
dry. Once dry, add another single coat
of PVA immediately prior to plastering.
Fill gap between speaker and
surrounding area
It is important to ensure that plaster is
pushed into the 2mm (5/64”) gap that
surrounds the speaker. This will create
a strong bond between the edge of the
speaker and the plasterboard/render.
This prevents any cracks appearing in
the final skim finish.
IMPORTANT: There MUST be a gap of
2mm (5/64”) all the way around the
speaker edge. If there isn’t simply
remove the speaker and increase the
aperture size accordingly.

Plastering and decorating continued...
07
Apply joint tape
Apply professional plasterboard joint
scrim (Amina recommend use of a self
adhesive fibreglass scrim tape) over the
joint between the speaker and the
surrounding wall.
Plastering
Use standard finishing plaster for large
areas. For patch plastering use a repair
plaster or joint compound such as
British Gypsum Easi-fill®
Important: To ensure proper operation
and sonic performance, no more than
2mm (5/64”) of plaster/compound must
be applied to the surface of the panel.
The working environment must be dry
enough to allow the plaster finish coat
to dry within hours, not days.
Decorating
Allow your plasterwork to dry
completely. Test the speaker again.
You can then paint the surface or
hang wallpaper in the usual manner.
Evolution Series speakers have been
optimised for up to 3 coats of
emulsion once plastered. Additional
coats will cause very small
reductions in the maximum sound
pressure levels achievable.

Testing the speakers
08
Important: Always test the speaker before plastering over it.
CAUTION:
Without plaster on the surface of the speaker it is highly efficient and will generate very
high sound pressure levels with minimal power input. Take care to protect your ears when
testing at this stage.
Using a multimeter and without the APU750 crossover connected, check the nominal
impedance (DC resistance) of the HF and LF loudspeaker at the amplifier end of the
speaker cable. Allow for approx. +/– 10% for cable resistance. The impedance should be 4
Ohm for both speakers.
Amina recommends a tone sweep be used at a moderate volume level (0.5 Vrms). Such
a test will quickly highlight any buzzes or rattles that could be caused by loose screws,
cables touching the speaker or loose elements/studs within the wall itself.
If the plasterboard is not securely fastened to the joists this could also create a buzz or
a rattle. Apply more screws if necessary - particularly around the speaker location.
Ensure that the speaker cable is not touching any part of the speaker (or backbox) as
this can lead to buzzes and rattles. To avoid this it is advised to lay the cable behind the
mineral wool or other wadding.
If metal studs are used, ensure the crossover point of the studs are secured together.
This can be achieved by applying drywall screws through the wall surface and through
the metal joists. If they are not secure this may well lead to audible vibrations and
rattles.
Check cable continuity back to the amplifier by using a multimeter to mark up the
cables correctly for the HF and LF panels.
Play music to check for buzzes and rattles during transient peaks. Do not judge the
speaker’s sound quality at this stage. Once plastered over it will sound as intended.
Always connect the APU750 when testing, except when measuring impedance.
Perform these tests again after the plaster is dry.
If the correct 2mm thick plaster coat has been applied, the speaker face, when tapped
with fingers, will sound slightly more hollow than the surrounding areas of plasterboard.
If there is little or no difference between these two sounds it is almost certain the
plaster coat is too thick. This will compromise the speaker performance.
Amina have a lot more information available from its technical help desk for those wishing
to measure frequency response curves at different stages of the installation.
Please contact [phone] for assistance.

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.

Speaker Orientation
The AIW750E can be installed either in portrait or landscape orientations, but has been
optimised for portrait orientaion and for the HF and LF panels to be positioned one
above the other.
For critical listening in ceilings, e.g. a 5.1 surround system, ensure that the orientation of
all speakers is the same relative to the main listening position and that the top of the HF
speaker is positioned closer to the walls.
Recommended Speaker Setup
“HiFi” position - low in wall
The spacing between LF and
HF should be:
80mm min - 200mm max.

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.

Maintenance and cleaning
Once your AIW750E speaker is plastered into your wall or ceiling, it requires no physical
maintenance. Your wall or ceiling can be cleaned with products appropriate to the finish
finally applied to the plaster surface.
The wall or ceiling can be painted or redecorated any number of times (see proviso -
page 07, step 5). Extreme care should be taken when removing wallpaper type
coverings to ensure the plaster surface is not damaged. If damage to the plaster work
occurs, use repair plaster to restore the plaster surface prior to re-decorating. Amina
Technologies Ltd recommends British Gypsum Easi-fill® repair plaster.
Avoid pushing the wall or ceiling surface immediately in front of the speaker. Excessive
excursion, whilst unlikely to damage the speaker, will undoubtedly cause the plaster to
crack around its perimeter.
Reliability
Correctly installed and used within its specification, the AIW750E speaker is designed
to give many years of trouble-free service. The vibrational soundboard technique used
by the AIW750E has very few moving parts. Compared to a conventional moving coil
speaker these movements are insignificant. Whilst the human touch can feel the tiny
movements, they cannot be seen by the naked eye. Such small movement of this
electromechanical structure means the long term reliability is enhanced compared to
the much larger movements of conventional loudspeakers.
Removal
In the unlikely event of a problem developing with the product, or you simply wish to
remove the item to change its location, please refer to the following guidelines:
Locate the speaker by tapping the wall or ceiling listening for a hollow sound compared
to the rest of the wall/ceiling. Then, with a sharp chisel or decorator’s scraper, carefully
chip into the plaster along the edge of the speaker to expose a small area of the panel
surface. To ensure you do not damage the panel, hold the tool at an acute angle to the
wall or ceiling.
Now, holding the scraper almost parallel to the panel surface, work outwards towards
the product’s corners easing the plaster away from the panel (during this process,
attempt to remove as little plaster as possible). Do not worry if the panel surface
receives marks or indented scratches during this process (it should not, however, have
holes entering through to the unique honeycomb panel). Once the product is plastered
back into its original or new location, the new skim of plaster will cover all these
imperfections and the speakers performance will not be unduly affected.
Clear the surface plaster material from the surrounding plasterboard to expose all the
joint tape and subsequently remove it. Use a narrow chisel or flat blade screwdriver to
remove the plaster and expose the screws at each corner of the product. Using a
suitable screwdriver, remove the four screws and then ease the product from the wall or
ceiling and disconnect the speaker cable. Leave all eight fixing blocks or the BackBoxes
in place as these can be used to support a small section of plasterboard when making
good the wall or ceiling.
If the product needs repairing, please return it to your supplier or Amina Technologies
Ltd again leaving as much plaster on the panel surface as possible. Once repaired, the
product can be refixed into position following appropriate installation steps detailed
earlier within the manual.
For further details on removal, please see the Amina website: www.amina.co.uk

Troubleshooting
13
Thorough testing of the speakers should be carried out both prior to and after plastering to
avoid time consuming repairs or modifications at a later stage. Should you encounter any
problems at either of the test stages, the following guide is designed to help determine
possible problem areas.
Advice for testing:
When testing always use a basic sound system (amp, source, speakers) to eliminate the
possibility of faults with other more sophisticated components, such as control systems.
Test at low and medium volumes and be careful not to exceed the specific speaker model’s
recommended power. Using tone sweeps or music as test material, listen for distortion,
buzzing or rattles at appropriate levels. Using test discs or music, confirm that all channels are
in-phase.
Low or No sound output:
Check continuity of all cables.
Check that all cables and connections are made correctly, are intact and that all channels are
correctly phased (+ to + and - to - from amp to speaker).
Using an impedance meter, check the nominal impedance of the HF and LF speakers (APU750
must not be connected) both at the terminals and the amp end of the cable. Do these
measurements match each other? (Allowing for the small impedance increase of less than 1
Ohm along the wire length) do they match the stated nominal impedance on the speakers
specification label? If the nominal impedance does not match the product’s stated impedance,
a speaker driver may be open circuited or short circuited. If so, the product may need to be
returned to Amina for repair or replacement.
If the nominal impedance at the end of the cable is very different to the impedance at the
speaker, check your cables. Cuts or nicks in the cable along its length can dramatically
increase impedance or create a short circuit, dramatically lowering the impedance.
Distortion, buzzing or rattles at modest volumes:
Try to identify the location of the buzz or rattle. It may be caused by a loose screw or other
mechanical object. Check the assembly and ensure screws and fixings are tight.
If the rattle persists, remove the speaker from the wall and check your wiring to the product.
Ensure that wires, with the speaker in the final location, are not resting against the speaker or
backbox (if used), causing vibrations.
With no audio signal applied, lightly push the speaker face in and out at its center. Listen
carefully for rubbing on the driver, which may sound like scratching. This may indicate the
speaker has been over driven and subsequently damaged. The speaker will need to be sent to
Amina for repair.
Very low output after speaker passes electrical tests:
With no audio signal applied, lightly push the panel in and out at its center. Listen carefully
for rubbing voice coils on the driver, which may sound like scratching. This may indicate the
speaker has been over driven and subsequently damaged. The speaker will need to be sent to
Amina for repair.
Distortion at higher volume levels:
Diffuse source panel loudspeakers of this type have an extremely fast response, articulating
the signal from your audio system very accurately. Take your system back to the bare
minimum (amplifier, source and speakers) to eliminate distortions introduced by other
components.
When using your amplifier at maximum power levels, or if the input of your amplifier is being
overloaded, the signal level may be ‘clipping’. With some conventional speakers this may not
be evident, but with a diffuse source panel speaker you are much more likely to hear the
distortion. Consider adjusting or upgrading your system.

Spacesaver information
Using the spacesaver for pre-install
The AIW/Evolution Series spacesaver is
designed to be pinned/taped to joist work
prior to the plasterboard/drywall being fitted.
Your speaker cable can then be secured to
the spacesaver using the holes provided.
There are two ways to secure the speaker
cable in position. The first is to pull the cable
through one (or both) of the holes and tape
in position.
The other method is to again pull the cable
through the two holes, loop and tie the cable
in position.
