Installation Instructions

For invisible Integration into
Furniture and Wall Panels

The Speakers of the DE Plan inside® series are special built-in
versions to be installed in furniture and wall panels. The speakers
are back-mounted onto the front of furniture or panels made of
wood, MDF or similar materials and directly resonate through
these surfaces.
This surface is activated without an intermediate membrane,

which makes DE Plan inside models extremely effi cient and gives

them an extensive, linear frequency range.

The reproduction characteristics depend very much on the
material in which the speakers are installed and the acoustics
of each room. As a result, our system controllers or DSP power

amplifi ers should always be used to achieve the best sound

pattern.

information. These are available at: www.lb-lautsprecher.de/en/

Installation of DE Plan inside® in furniture panels (wood, MDF or Sandwichboards)

1. Milling of furniture panels

The recessed mounting area is milled into the rear surface to a
wall thickness of 3 mm.
Attention: Please make sure that the panel is not getting distorted
by milling. You can also use a sandwich panel with 3 mm HDF and
milled MDF with recessed wall thickness.

2. Surface of the furniture panels

If the furniture is verneered, coated or varnished, the inner side
of the milled area should be treated accordingly. At least the
inner side of the milled area should be primed in order to avoid
distortion.

Refer to individual
product datasheets
for more detailed
technical information.
These are available
at: www.lb-lautspre­cher.de/en/Unsichtba­re-Lautsprecher

3. Pretreatment of the milled furniture in the area of the exciter
(only if the milled area is not varnished)

To bind the surface in the area of the exciter (8 × 8 cm) treat the
milled MDF with the cyan-acrylate Special 483 adhesive. Spread
the adhesive by using a brush or spatula. Let the adhesive
harden for at least 30 minutes.

4. Sticking the speakers in the milled furniture or wall panels

First degrease the mating surfaces with alcohol (white edge
plating and carbon plating from exciter).
Then apply the 2C adhesive (included in delivery) on the white
plating and carbon plating from exciter in a solid homogeneous
seam (see picture above).
Afterwards insert the speaker rapidly into the milled area from
furniture or wall panel (the membrane with adhesive face down).

Weigh down the Speaker for 20minutes (with about 5 – 10 kg)

Important Informations

 Make sure that the carbon plating from exciter has contact

with the furniture or wall panel when sticking.

 The adhesive has a short pot life of 5 minutes and quick

setting, afterwards no further adjustments are possible.

 Damage resulting from incorrect handling is not covered by

the warranty.

Application of the 2C adhesive – Please contact us if you have any questions.
