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.
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 farenheit)
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 occupation buildings.
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.
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.

How to use this manual
The following pages contain step by step advice to help you achieve a successful installation of your
AIW350E loudspeaker
AIW350E loudspeakers 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 BackboxFS (sold
separately) or our basic fixing block kit. Whenever possible we recommend you use the BackboxFS as
the AIW350E has been tuned to work optimally in this setup. The backboxFS also reduces (although
doesn’t entirely stop) the rearward sound output of the AIW350E which is important when considering
the amount of 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
seperately). 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.
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 (i.e is it a retrofit installation or a new build?).
Section : 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.
Section : Testing
This section advises you on the correct procedures for speaker testing.
Section : Finishing
This section covers plastering and decorating once your speaker has been installed correctly. It may
again be necessary to refer to Section B in order to apply the correct plastering method.

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 wall studs. Ensure the
spacing between them is at least 350mm
(133/4”) for a portrait orientated speaker.
01
Create 455 x 350mm aperture
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 backbox. 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.

SPACESAVER:
The supplied Spacesaver may be used to
show the position of the speaker pre-install
by securing it to the wall.
Secure the speaker cable to the Spacesaver
before any building electrical inspection.
See page 30 for full details.

Cavity installation continued... 06
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.
03
Attach fixing blocks (x4 per speaker)
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 AIW350E speaker
Connect the speaker cable to the speaker
using a high quality crimping tool.
Your AIW350E speaker is fitted with blue butt
splice crimp connectors which are suitable
for speaker cable thicknesses of 1.5mm2-
2.5mm2(16 - 14AWG). This type of connector
ensures a permanent connection is created
inside your wall cavity.
05
Secure the speaker to the fixing blocks
Important: Ensure there is an all around 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.

Cavity installation with backbox 08
Create 455 x 350mm aperture
Choose speaker location by following step 01,
page 5. 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 the aperture is created
between supporting joists or stud work.
We strongly advise that joists are not cut to
make space for the backbox. 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.
01
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.
Doing this will make it easier to connect the
cable to the speaker later on in the
installation process.
Position the backbox within the aperture so
as to rest it 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 75mm/3" cavity depth is required to fit a
Backbox FS or Backbox FSS.

corner.
Ensure the speaker face is flush with the front
of the plasterboard wall and that everything
is firmly held in position. Shims may be
necessary. (See section B)
Amina backboxes (Backbox FS and FSS) are
designed for 12.5mm (1/2”) plasterboard.
Shims can be supplied to adapt the backbox
for different plasterboard thicknesses.

Solid wall installation with backbox
1 1
Create aperture in brickwork
Using the combination of an angle grinder
and a jackhammer drill, create a cavity of
460mm x 355mm (182/16” x 1331/32”) within the
brickwork.
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 this thickness from 50mm (2”) to
calculate the minimum cavity depth you will
need to create.
01
Create channel for cable
Using an angle grinder or hammer and
chisel, create a channel that runs into the
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 backbox. There are
four slots in the base of the backbox and
using suitable screws (not supplied), fix the
backbox to the brickwork within the cavity.
Ensure the front edge of the backbox aligns
flush with the front face of the surface which
will be plaster skimmed.
We recommend shims are fitted behind the
backbox to achieve a level solid fixing. It is
recommended to add sound absorbing
mineral wool (1” maximum thickness) to the
inside of the backbox and expanding foam
around the sides to prevent resonance.
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 backbox to the
front edge of the render (as shown in the
lower section of the image)
03
Connect speaker
Connect the speaker cable to the speaker
and crimp securely using a high quality
crimping tool.
Locate the speaker within the aperture and
rest it against the 6 mounting tabs on the
backbox.

Secure the speaker
Remove the backing paper from the 6
adhesive pads on the backbox 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 backbox) to fix the corners of the
speaker to the four corner support tabs.
If the correct steps are taken to align the
backbox with the front face of the
wall/render, the loudspeaker, when screwed
in place, will also sit flush with the front face of
the wall/render.
Do not adjust the screws in any way, make
sure they are tightly screwed in place and
the whole assembly is firm.

Speaker alignment required for plastering
After removing a 30-50mm (3/16 - 2”) wide
section of existing plaster surrounding the
cutout, the front face of the speaker should
be flush with the paper face of the
plasterboard.
This is the method that will be used during
plastering (Section D). It positions the speaker
to be patch plastered with a 2mm (5/64”)
skim across the speaker front, blended with
the existing plaster on the plasterboard.
Amina recommend British Gypsum Easi-fill®
which allows a smooth accurate finish using
fine sandpaper or a wet sponge.
