Important Informations

We recommend that all lining, plastering and painting work is
carried out by professionals. The speaker will only deliver the
desired visual and acoustic results if it is installed correctly.
Drying times between the individual steps must be observed.
The models in the DE Plan series are designed to be installed
in walls/ceilings that are 10 – 35 mm thick (= max. two drywall
sheets + 10 mm thick back box). Solutions for other installation
scenarios are available on request.

Damage resulting from incorrect handling is not covered by
the warranty.

Refer to individual product datasheets for

1.1 Mark out the opening for the speaker and

also mark the positions of the mounting feet to

make sure the screws are drilled in the correct

position later. Use the assembly frame as a

template.

1.2 Cut out the opening with a utility cutter

or saw (only cut out the rectangular outline).

Make sure the edges are smooth.

1.3 Use a sharp utility cutter to taper the

edges of the aperture to an angle of 45

degrees.

1.4 Smooth the edges with sandpaper (100 –

150 grain). Remove any bits of drywall paper

that are protruding.

1.5 Insert the assembly frame with the

mounting feet attached.

1. Installation in Drywalls and -ceilings

Turn the feet to the inside if you are installing

the speaker in a wall/ceiling where there is

limited space.

1.6 Drill the quick- x screws supplied through

the front of the drywall and into the mounting

feet. Do not use standard drywall screws!

1.7 Remove the assembly frame. Only the

mounting feet and springs remain in the wall/

ceiling. Use the long springs (65 mm) for wall/

ceiling thicknesses of 25 mm or more.

1.8 Connect the speaker system.

MAKE SURE THE POLARITY IS CORRECT.

DE Plan speakers can be installed without
back boxes in closed ceilings and walls.
DE Plan 600 SUB subwoofers must be
installed with a back box to ensure they
can be correctly balanced. Back boxes
from the EG Plan series are usually used
in acoustic ceilings or to reduce sound
transmission into adjacent rooms (see
page 5).

Use springs with 55 mm and screws with 70 mm for wall thickness from 10 to 25 mm.

1.9 Install the speaker: Insert the drill bit into

the head of the assembly screw in the speaker.

Drill the speaker into the wall/ceiling. Use the

long screws supplied with your product for

wall/ceiling thicknesses of 25 mm or more.

1.11 Use the assembly screws to adjust the

speaker so that the plastic membrane protrudes

by approximately 0.5 mm in front of the wall/

ceiling on all sides.

1.10 Test the speaker and wiring, for example,

by playing music. (The speaker will not

produce the correct sound until the surface is

nished.)

1.13 Plaster and sand down (grain 120 – 240)

the seam between the wall/ceiling and the

membrane twice, and plaster over the screw

holes twice.

1.14 Only sand the edge of the membrane

and only apply light pressure when doing this.

Make sure no plaster is left on the membrane.

1.15 Use a foam roller to evenly apply

the dispersion adhesive delivered with

your product over the membrane and the

surrounding area.

1.16 Place the glass ber lining over the

adhesive area while it is still moist. Make sure

the lining is centered.

1.17 Use the roller to apply another light coat

of adhesive over the lining. Make sure the

surface is smooth. Allow the adhesive to dry

completely (overnight).

1.18 Apply one very light coat of ller over

the entire area. Apply two to three very light

coats of ller to the seam where the lining

meets the wall/ceiling and sand down until

you have a ush surface.

1.19 IMPORTANT! Before you start painting,

make sure that the ller has dried completely

(overnight). If it is not completely dry, the paint

may not adhere correctly to the surface!

1.20 Paint the area. The high frequency level

will decrease slightly if three coats or more are

applied (approx. 0.5 - 1 dB per coat).

1.12 The membrane should not be too deep

otherwise you will not be able to plaster over

the seam.

2. Installation with Back Box in Non-Concrete Walls and Ceilings

Use EG Plan series back boxes in walls
or ceilings that are not closed (e.g. for
acoustic ceilings, ventilated ceilings,
open recessed lighting), or if you need
additional sound proo ng for adjacent
rooms. The mounting feet are already
attached in these back boxes. You will
have to make the holes for cables in the
back box yourself.

Frequency range of DE Plan speakers with its infl uence of paint coating

The sound quality of DE Plan speakers
depends on the material placed over the
membrane. The membrane is designed
to be covered by the glass  ber lining (34
g / m²), a thin layer of  ller, which is then
sanded, and 1 – 3 coats of paint (emulsion).
If any other material is applied over the
membrane (e.g. thicker lining, thicker coats
of  ller or acoustic plaster), this will cause
a drop in sound pressure levels in the mid­high range. You can compensate for this
using a system controller or an equalizer,
for example. Please contact us if you have
any questions.

Place the back boxes behind the drywall
sheet. Glue and screw them in position.
Fit the acoustic  eece into. Pin the
springs on the mounting feet. Use the
long springs supplied for wall/ceiling
thicknesses of 25 mm or more. Drill the
speaker into the wall/ceiling and make
sure it is level (installation step 1.8
onwards).

Use springs with 55 mm and screws with 70 mm for wall thickness from 10 up to 25 mm.
Use springs with 65 mm and screws with 80 mm for wall thickness from 25 up to 35 mm.

3.1 Make the opening in the
brickwork.

3.2 Install the EGB series plastic back
box using mortar or a similar mate­rial. Make sure the box is free from
mechanical stress and fix in place
using adhesive or plugs (otherwise
the position of the speaker may
shift visibly over time).

3. Installation in Solid Walls

3.3 Apply the plaster mesh (to prevent
cracks forming at the seam) and
plaster to the edge of the opening.

3.4 Fit the acoustic  eece into the back
box. Pin the springs on the mounting
feet.

3.5 Connect, install, test and adjust the
speaker (see steps 1.8 – 1.11).

3.6 Plaster the edge and sand until
smooth (see steps 1.12 – 1.13).

3.7 Place the glass fiber lining over
the plastic membrane
(see steps 1.14 – 1.16).

3.8 Plaster and sand down the lining
and seams
(see steps 1.17 – 1.18).

3.9 Paint over the area
(steps 1.19 – 1.20).

When installing speakers in solid walls,
please use our EGB series plastic back
boxes. The mounting feet are already
attached in these back boxes. You will
have to make the holes for cables in the
back box yourself. The speakers can
then be installed in the same way as
for non-concrete walls/ceilings. Please
note that the speaker is not designed
to be used with rough render, textured
render or similar plastering. Applying
these kinds of material over the speaker
membrane will have a major impact on
sound (see page 5).

4.1 Insert and affix the EGB series
plastic back box in the formwork
ready for the concrete ceiling to
be cast (make sure the correct
reinforcement is used above and
below the back boxes).

4.2 Once the ceiling is cast, remove
the rigid foam insert from the back
box.

4. Installation in Concrete Ceilings

4.3 Fit the acoustic  eece into. Pin the
springs on the mounting feet.

4.4 Connect, install, test and adjust the
speaker (see steps 1.8 – 1.11).

4.5 Plaster the edge and sand until
smooth (see steps 1.12 – 1.13).

4.6 Place the glass fiber lining over the
plastic membrane

(see steps 1.14 – 1.16).

4.7 Plaster and sand down the lining
and seams (see steps 1.17 – 1.18).

4.8 Paint over the area

(steps 1.19 – 1.20).

If you are installing speakers in a
concrete ceiling, EGB series plastic
back boxes must  rst be cast into the
concrete ceiling (precast concrete
ceilings and concrete ceilings cast in
place). The mounting feet are already
attached in these back boxes. You will
have to make the holes for cables in
the back boxes yourself. The speakers
can then be installed in the same way
as for non-concrete walls/ceilings.
