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,
strong vibrational forces, 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.
>
>
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.
Do not clean this product with chemical
solvents as this may damage the finish. Use a
clean, dry or damp cloth.
>
When plastering over, ensure only 2mm of
material covers the product. More than this will
degrade the performance of the product and
could lead to product failure.
ENVIRONMENTAL:
Before installing, ensure that the building is environmentally 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 finishing
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.
Equally, using the product in simple (stud or rafter with plasterboard or floor board directly
attached on both sides) stud walls & wooden rafter ceiling/floor structures will also transfer
substantial sound energy to the other side of the wall or floor above. It is therefore recommended
that the product be fitted in acoustically isolated stud walls or ceiling sections where possible.
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.
FIRE PROTECTION:
When making an intrusion into an internal wall or ceiling to install an Amina loudspeaker be sure
to check the appropriate regulations pertaining to the required fire rating. Depending on the
location of the intrusion and the applicable regulations it may be necessary to build in or install
additional fire rated components or products to surround the speaker and back box. Amina
Technologies take no responsibility for the correct specification and installation of any such fire
protection system that is required behind their speakers.

How to use this manual
The following pages contain step by step advice to help you achieve a successful installation of
your IQ Series loudspeaker.
The IQ Series loudspeaker can be installed into walls or ceilings of various construction types.
This installation guide covers the two basic building construction types; plasterboard cavity
walls/ceilings and brick/concrete walls/ceilings. For other construction types please contact
Amina.
Cavity wall or ceiling
This is the most common type of installation and requires you to use the Amina BackboxCV or
our basic fixing block kit (both BackboxCV and the basic fixing block kit are sold separately).
Wherever possible we recommend you use the BackboxCV as the IQ Series loudspeaker has
been tuned to work optimally in this setup. The BackboxCV also reduces (although doesn’t
entirely stop) the rearward sound output of the IQ Series loudspeaker which is important when
considering the amount of airborne sound transmission that is acceptable through to adjacent
rooms/properties.
Solid wall or ceiling
For installation into brickwork or concrete you will need to pre-install an Amina BackboxSW
(sold separately). When the BackboxSW is installed according to this guide it will position the
speaker correctly and securely in the wall/ceiling, ready to be plastered over.
The details below and the flow chart on the opposite page will allow you to select the correct
installation steps to follow for your particular type of installation.
A
Section : Preparing the wall / ceiling and fixing the product
In this section, select the type of installation you will be carrying out and begin from the start
page given. This will direct you through the stages, step by step. Throughout the step by step
process, reminders will advise you to view specific pages within Section B.
At this point you will need to ascertain the specific page that best matches your installation
requirement within this section (e.g., is it a retrofit installation or a new build?).
Section B
: Alignment and plastering preparation
Section B is the reference section which is to be used in conjunction with Section A. Please
ensure the correct alignment and plastering method for a retrofit installation or a new build is
followed. Reminders on each page throughout Section A will guide the installer to the correct
reference page.
C
Section : Testing
This section advises you on the correct procedures for speaker testing, both before and after
plastering.
D : Finishing
Section This section covers plastering and decorating once your speaker has been installed and aligned
correctly. It may again be necessary to refer to Section B in order to apply the correct
plastering method.

01
Locate joist 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 305mm
(12.01”) for a portrait orientated speaker.

Important: If the space in between joists is
less than 350mm (133/4”), consider using
the AIW350E/S200 loudspeaker which
only requires a 200mm (77/8”) wide cavity.

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 405mm x 305mm (15.95” x
12.01) as this is important further on into
the installation process.

03 Install speaker cable and insert insulation
Ensure all speaker cables are pulled
through to the speaker location with plenty
of slack. This will make it easier to connect
the cable to the speaker later on in the
installation process.
It is recommended to add sound absorbing
mineral wool inside the cavity to reduce
sound transmission behind the speaker and
limit cavity resonances. This is essential in
ceiling locations where the mineral wool
will also prevent debris falling onto the
rear of the speaker over time.
The mineral wool can rest against the back
of the speaker but not so much as to put
pressure on the panel.
Ensure the speaker cable is laid behind the
mineral wool and can not rest against the
rear of the panel.
04 Attach mounting blocks (x4 per speaker)
03
drywall screws
Position a fixing block under the
plasterboard at each corner of the
aperture. Fasten the thicker section of
the fixing blocks to the underside of the
plasterboard using two drywall screws
secured through the front face of the
plasterboard.
NB: ensure there is no gap between the
fixing block and the sawn edge of the
plasterboard aperture.
Important: The fixing blocks are designed
for 12.5mm (1/2”) plasterboard (1/2” and
5/8” in North American markets).
Please contact your supplier if you require
fixings for an alternative plasterboard
thickness.

Connect the IQ Series speaker
Connect the speaker cable to the speaker
using a high quality crimping tool.
Your IQ Series speaker is fitted with blue
butt splice crimp connectors which are
suitable for speaker cable thicknesses of
1.5mm2 - 2.6mm2 (16 - 14AWG). This type of
connector ensures a permanent
“shake-proof” connection is created inside
your wall cavity.
05
06 Secure the speaker to the fixing blocks
Top View
Important: Ensure there is an all round
gap of 2mm between the speaker and the
plasterboard. If necessary, increase the
aperture size before mounting the speaker.
Using drywall screws, fix the four corner
points of the speaker to the fixing blocks.
Pilot holes are not necessary as drywall
screws will easily self-tap into the fixing
block.
Ensure the front face of the speaker rests
in a position flush with the front of the
plasterboard and that it is firmly held in
position.

Choose speaker location and create
aperture by following steps 01 + 02 on
page 05. Use the cut-out template as a
guide.
Next, 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.
Using the
fold out tabs...
Use the fold out tabs at either end of the
backbox to help support it in a vertical
position before securing it to the
plasterboard.
A 75mm/3” cavity depth is required to fit a
BackboxCV or Firehood.
02 Fix backbox
01

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.

Create aperture in brickwork/ concrete
Using the combination of an angle grinder
and a jackhammer drill, create a cavity of
410mm x 310mm (16.14” x 12.2”) within the
brickwork. (460mm x 210mm for S-200
variants)
Before installing the backbox you will need
to know the thickness of render that will
be applied to the wall/ceiling prior to the
finish plaster skim.
Minus that thickness from 50mm (2”) to
calculate the minimum cavity depth you
will need to create.
01
02
Create channel for cable
Using an angle grinder or hammer and
chisel, create a channel that runs into this
cavity, this will allow the speaker cable to
be pulled into a suitable position within the
cavity.
We recommend the cable is run in a
suitable conduit to protect it.
Leave enough cable slack to allow
connection to the speaker when it is held
away from the cavity.

Install backbox
Make a small hole in one of the rubber
grommets and pull the speaker cable
through it and into the backboxSW. There
are four slots in the base of the backboxSW
and using suitable screws (not supplied),
fix the backboxSW to the brickwork within
the cavity. Ensure the front edge of the
backboxSW aligns flush with the front face
of the surface which will have the final 2mm
skim coat of plaster applied.

Mineral Wool
Expanding foam
We recommend shims are fitted behind the
backboxSW to achieve a level solid fixing. It
is recommended to add expanding foam
around the sides and rear to prevent
resonance and also to add mineral wool
(max 1”) to the inside of the BackboxSW.
NB: If there is a layer of render to be applied
or already applied to the brickwork, be sure
to align the front edge of the backboxSW
to the front edge of the render (As shown in
the lower section of the image)

Secure the speaker
Ensure the speaker cable is laid behind the
mineral wool and cannot rest against the
speaker itself.
Remove the backing paper from the six
adhesive pads on the backboxSW
mounting tabs, carefully position the
speaker onto the support tabs and apply
moderate pressure.
There should be an equal perimeter gap
between the backbox and the edge of
the speaker.
Use the flange head screws (supplied with
the backboxSW) to fix the corners of the
speaker to the four corner support tabs.
If the correct steps are taken to align the
backboxSW with the front face of the
render, the loudspeaker, when screwed in
place, will also sit flush with the front face
of the render.

Testing
Testing the speakers
C
Important: Always test the speaker before plastering over it and again once plaster is dry.
The following procedure is required as a minimum.
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 APU protection device connected, check the nominal
impedance (DC resistance) of the speaker at the amplifier end of the speaker cable. Allow
for approx. +10% for cable resistance. The impedance should coincide with the values on
the respective loudspeaker datasheets. If it measures significantly different, check for
breaks or shorts in the cable.
>
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.
>
Play music to check for buzzes and rattles during transient peaks: if these are apparent,
check the above points again. Do not judge the speaker’s tonal balance at this stage. The
overall speaker performance must be clean and distortion free, although at this stage it
will appear biased toward mid and high frequencies. Once plastered over the speaker will
have a fuller, richer sound.
>
Always connect the APU 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.
Full frequency response tests are recommended before and after plastering
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.

Finishing
Plastering and decorating
01
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 edge of the wall.
This further helps to prevent any cracks
appearing in the 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 (plasterboard installations
only)
If you are using a solid wall backbox,
ensure there is an even gap between
the speaker and the inside edge of the
backboxSW.
02
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.
D
Plastering and decorating continued...
03
Plastering
Use standard finishing plaster for large
areas. For patch plastering use a low
shrinkage repair plaster such as British
Gypsum Easi-fill®
Please refer to the appropriate page
in Section B (alignment and plastering
preparation for your specific installation
type). Pages 13 - 17
Important: To ensure proper operation and
sonic performance, no more than 2mm
(5/64”) of plaster must be applied to the
surface of the panel.
04 Decorating
Allow your plasterwork to dry completely.
Test the speaker again (see Section C,
page 18). You can then paint the surface or
hang wallpaper in the usual manner.
IQ Series speakers have been optimised
for three coats of emulsion once plastered.
Additional coats will cause very small
reductions in the maximum sound pressure
levels achievable.
Note:
Amina have separate guides for
information about installing the
product behind other materials and
surfaces such as wooden panels,
acrylic and melamine laminates.

APU150 / APU350 / APU550
Your IQ Series speaker must be used with an APU protection device or another approved
protection device. These include the APU-RS8E rack mount device or an Amina approved
active device (such as Cloud EQ in commercial systems) should be used. Please refer to
the instructions supplied with the APU devices and full warranty information for further
details.
Installation Backboxes
The IQ Series have been designed for optimum sound quality when used in the Amina
BackboxCV 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, but any effect will be very much installation specific.
When installed into solid walls or ceilings using the Amina BackboxSW, you may find that
your IQ Series reproduces slightly less low frequency output compared to a BackboxCV
installation. Also, depending on the building construction, there may be significant
mechanical sound transmission into adjacent rooms/properties (see inside front cover).
IQ Series Audio Characteristics
The IQ Series 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 means that
loudspeaker positioning is far less critical than with conventional speakers. Additionally,
just like the acoustic musical instrument, the IQ Series has excellent room filling abilities.
>
The IQ Series 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 IQ Series (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 IQ Series is very stiff
and undergoes very small amounts of movement in order to generate high sound pressure
levels. This means that the IQ Series is inherently “fast” making it a highly articulate
loudspeaker.
>
>
Wall or Ceiling Placement
The IQ Series are 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 IQ Series speakers are used in stereo or multi channel
systems, position them in the walls so that the centre point of an IQ Series speaker 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, the audio characteristics of the IQ
Series make exact positioning according to stereo 5.1 and 7.1 conventions far less critical.

Setup tips
>
Speaker Orientation
The IQ 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 IQ 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 (e.g. ALF80) is used.
System Requirements
From a system compatibility point of view your IQ Series (and it’s accompanying
APU protection unit) can be treated like any conventional 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 IQ 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: IQ 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 IQ 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, please contact Amina for their range of
loudspeakers supplied with 100V or 70V line transformers fitted.

Further details
Maintenance and cleaning
Once your IQ Series 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 24,
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 Amina IQ Series speaker is designed
to give many years of trouble-free service. The vibrational soundboard technique used by the
IQ Series 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
products’ 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 four fixing blocks or the BackBox in place as these can be used to
support a small section of plasterboard when making good the wall/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
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.
- Ideally professional test equipment should be used to record a full frequency response of the
loudspeaker before and after plastering.
>
No or low 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 speaker (APU 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 wall or ceiling and speaker 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 centre. 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 or
replacement.
>
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.
