SYSTEM DESCRIPTION 3
musikelectronic geithain GmbH ME 150
3 System description
The two 6.5-inch cone woofers of the ME 150 passive 3-way oorstanding loudspeaker are
responsible for reproduction of the low and mid frequencies and convincing with excellent linearity.
Both midwoofer systems are placed in a vented cabinet with a downward-radiating exit opening.
This design simplies the positioning of the loudspeakers for achieving optimal bass reproduction
in your listening room. A 1-inch dome serves as tweeter unit, located coaxially in front of the upper
midwoofer. The particular radiation characteristics, in connection with the coaxial arrangement, allow
a homogenous and natural sound pattern for a base width between 2 m (6′7″) and 3.5 m (11′6″).
Using a suitable AV receiver, the ME 150 oorstanding loudspeaker can be complemented with a
subwoofer from our BASIS series.
The general concept of the passive 3-way coaxial loudspeaker ME150 is characterized by its well-
balanced and low-distortion sound pattern and its high dynamic qualities.
“No ifs and buts, Joachim Kiesler succeeded to build an extremely living room friendly passive
loudspeaker. Its sound keeps up with the outstanding performance of the active monitors. A down-
to-earth speaker that does what it was created for - passing on the music just as it is being supplied.”
Rolf Linden-Brüning, “Hörerlebnis” magazine, issue 63 (2008)

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
Opening the device by unauthorized personnel leads to all claims under guarantee expire. In case of
destruction by overload, misuse or outside inuences there are no claims under guarantee.
POSITIONING 6

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

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 2 m (6′7″) or more than 3.5 m (11′6″)
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 150
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 = 2 m … 3.5 m (6′7″ … 11′6″)
In case installation in the prescribed way is not possible in your listening room most decoding
devices allow adjustments of single speakers.
