Introduction
2” High-end in-wall speaker
The MERO speakers will blend beautifully into any interior, making only their extraordinary
sound draw your attention with their nearly invisible design. Their slim grill with very
thin border of only 1 mm and limited grill depth extrudes the surface by only 3.2 mm
when installed.
Their grilles are retained by neodymium magnets which enables assembly in seconds,
while powerful enough to keep it fixed, even when subject to vibrations or if touched. Their
applications range from residential Hi-Fi and home cinema installations to Multi-Zone
systems, unobtrusive installations in lounges, bars, boutiques and offices.
The selection of high-grade materials in combination with accurate acoustics
craftmanship makes the MERO speakers superior in their class. The Ultra-compact
size enables the MERO2 smoothly integrate into any interior like no other loudspeaker.
The outer dimensions only measure only 146 x 98 mm and the built-in depth which
doesn’t exceed 70 mm allows installation in any surface while being unobtrusive.
The 2” full range aluminum cone driver is protected against overload through an integrated
self-resetting protection circuit. All these details share their part to the quality of the
Mero 2, resulting in an highly reliable loudspeaker producing a pure sound with an RMS
power of 10 Watt.
An elegant look with minimal visual impact is created by the slim grill with a very thin
border, while great ease and installers convenience is guaranteed using the quick-fix
mechanism with Gold-CON connectors. The grill is held in place using neodymium
magnets, providing a quick and stable assembly. Installation can be done both vertically
and horizontally.

Installing the MERO
Introduction
The MERO speakers feature a quick-fixing mechanism, which allows quick and easy
installation of the loudspeakers in only a few minutes.
The installation of the MERO speakers requires a minimum amount of installation skills.
Before the loudspeaker is installed, the location whereto it will be mounted should be
carefully checked to make sure the surface can support the weight of the speaker and
no lines for water, gas, electricity or other supplies are crossing this point.
Installation procedure
To ensure a safe and secure mounting of the loudspeaker, the installation should be
done according to the procedure described below:
1) Firstly cut a hole into the surface whereto the loudspeaker should be installed with
dimensions 128 x 80 mm. The included cutout template can be used for an easy
marking of the installation hole.
80 mm
128 mm
2) Provide the loudspeaker connection cable through the mounting hole. Make sure
the used connection cable is sufficiently thick. The required cable thickness depends
on its length.
3) Take the loudspeaker, and remove the front grill which is held in place by
neodymium magnets. The front grill can be easily removed by gently pulling it.

4) Connect the loudspeaker connection cable to the gold plated spring clamp
connectors. Press the button of the corresponding terminal down and insert
the connection cable. After releasing the button, the cable is connected to the
loudspeaker. The Red terminal indicates positive (+) pole and the Black terminal
indicates the negative (-) pole.
Mind the polarity markings when wiring the loudspeaker cables.
Maintain the same polarity and wiring colour coding throughout the entire system to
avoid any mistakes causing malfunction or distortion.
5) Once the connections are made, the loudspeaker can be installed in the provided
mounting hole. Make sure the mounting clips of the loudspeaker are rotated inwards,
making the speaker fit through the hole. Insert the speaker through the provided
mounting hole, and use a screwdriver for tightening the fixing screws.
Once the screws are tightened a quarter turn, the mounting clip will rotate outwards
and will be locked behind the surface. From then on, the loudspeaker is anchored in
the surface and thus can not fall.
6) After the screws are tightened and the speaker is level with the surface, the front
grill can be assembled to the loudspeaker.
