SYSTEM DESCRIPTION 3
musikelectronic geithain GmbH ME 25
3 System description
The ME 25 2-way coaxial loudspeaker is the most compact passive loudspeaker in our ME series.
Its 5-inch woofer system and its 1-inch tweeter system are integrated into a vented cabinet and
feature excellent converter linearity. The ME 25 performs very well as front and effect loudspeaker
in 5.1 surround systems; in connection with a suitable AV receiver, it can be complemented with our
BASIS 11K subwoofer. Its mid-treble range qualities are highly independent of room characteristics,
which contributes to uncomplicated spatial positioning of the loudspeaker. The particular radiation
characteristics allow a well-balanced listening experience for a base width between 1 m (3′3″) and
3 m (9′10″). The ME 25 can be operated horizontally. Optionally, a stand in matching veneer with
integrated cable duct is available.
The general concept of the passive 2-way coaxial loudspeaker ME25 is characterized by its minimal
dimensions, its well-balanced and low-distortion sound pattern and its high dynamic qualities.
“In spite of the minimal dimensions, these transducers sounded so true, natural and still musical - it
really left a mark on us. When listening to these transducers, their perfect play makes you suddenly
feel like a real audio engineer. Suddenly you hear details which you believe to never have heard
before.” DVD & Surround Test 06/2003

4.5 Cleaning
The speaker is made of real wood veneer and needs to be nurtured in the same way as furnishings.
We advise quality wax polish to ensure durability of the veneer. Surfaces can also be cleaned with
tidy, slightly damped, fuzz-free, smooth cloth.
4.6 Environmental conditions
Ensure the following environmental conditions in your listening room:
;Operating temperature +15 °C ... +35 °C (+59 °F ... +95 °F)
;Storage temperature range −25 °C ... +45 °C (−13 °F ... +113 °F)
;Relative humidity 45 % ... 75 %
4.7 Guarantee acknowledgements

destruction by overload, misuse or outside inuences there are no claims under guarantee.
POSITIONING 6
musikelectronic geithain GmbH ME 25
5 Positioning
Our speakers do not impose special requirements neither in stereo nor in multichannel set-ups.
Nonetheless speaker positioning has inuence on listening impression because every room is
individually designed and furnished. The following advices are just guidelines that ease proper
positioning. In addition we offer a measurement service to take advantage of the capabilities of your
listening environment.
5.1 Positioning near walls
When speakers are installed near walls sound quality is physically affected. Every customary speaker
behaves as a punctual sonic source in the low frequency range, with sonic waves spherical radiated
without any constructional measures. Back wall reections are unavoidable.
For optimum listening experience a minimum distance of 50 cm (19.7″) to walls and furniture should
be ensured. Avoid corner installations because unwanted bass accentuation could arise.

POSITIONING 7
musikelectronic geithain GmbH ME 25
5.2 Stereo operation
The optimum position of the speakers in your listening environment is the so-called stereo triangle
(see gure). The base distance between the speakers and the distance to the hearing zone form an
equilateral triangle (stereo triangle). A distance less than 1 m (3′3″) or more than 3 m (9′10″) should
be avoided. For precise,spacial reproduction turn the speakers inside,directed to the hearing zone.

;Adjust the speaker horizontally to the height of the ear at the listening position
POSITIONING 8
musikelectronic geithain GmbH ME 25
5.3 Surround operation
In surround operation the stereo triangle (see Stereo operation) is extended to a circle. The hearing
zone is the centre of this circle. Position all speakers in the same distance to the hearing zone. The
centre speaker is positioned in the middle between both front speakers. Pay attention to positioning
the front and rear speakers horizontally along one plane. The angle between centre and rear speakers
should be about 110° – 120°.
;Distance between speakers and your listening position a = 1 m … 3 m (3′3″ … 9′10″)
In case installation in the prescribed way is not possible in your listening room most decoding
devices allow adjustments of single speakers.
