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.

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).
