1 Introduction
Dear customer,
Thank you for the trust you have put in us by buying these speakers. You decided upon a quality
product that in regard to tonal and technical characteristics complies to the utmost expectations.
The usual burn-in period is not required, because the speakers are articially aged in-house.
Please read the technical description and manual to take advantage of the capabilities
of these speakers and ensure safe operation.

SYSTEM DESCRIPTION 3
musikelectronic geithain GmbH ME 160
3 System description
The ME 160 3-way coaxial loudspeaker has been optimized for the sound reproduction in acoustically
less attenuated living rooms. Interfering reections on oor and ceiling surfaces often result in a
diffuse and less precise sound pattern. The ME 160 passive oorstanding loudspeaker avoids this
problem thanks to its vertical directivity in the mid and treble ranges. This radiation characteristic is
achieved with a special geometric arrangement of the loudspeaker systems.
Bass and mid frequencies are reproduced by two 8-inch cone loudspeakers that are fed from separate
lter branches. Both systems are placed in a vented cabinet with a downward-radiating exit opening.
This design simplies the positioning of the loudspeakers for achieving optimal bass reproduction in
your listening room.
For the treble range, the oorstanding loudspeaker is equipped with three vertically arranged 1-inch
dome tweeters which are located in front of the upper midwoofer system. This technology both
expands the dynamic range and increases the usable listening distance to ve metres. In combination
with the coaxial arrangement, the result is a homogenous and natural sound pattern.
The general concept of the passive 3-way coaxial loudspeaker ME160 is characterized by high
efciency, sound neutrality and dynamic qualities.
“All in all it is an elegant oorstanding loudspeaker displaying true understatement, reluctant to push
itself to the fore. However, all understatement is gone immediately if you feed the ME160 with any
music material independent of the genre. Then it really comes out, the proverbial wolf in sheep’s
clothing...” Meik Wippermann, “Hörerlebnis” magazine, issue 72

4.3 Unboxing
The speakers are shipped in proper condition. Unpack the speaker carefully and check for visible
damages. In case of damages report them to your retailer. Keep the packaging, in case the speaker
has to be transported in the future.

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 inuences there are no claims under guarantee.

POSITIONING 6
musikelectronic geithain GmbH ME 160
5 Positioning
Our speakers do not impose special requirements neither in stereo nor in multichannel set-ups.
Nonetheless speaker positioning has inuence 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 reections 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.

;Minimum distance to wall b ≥ 50 cm (19.7″)

POSITIONING 7
musikelectronic geithain GmbH ME 160
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 5 m (16′5″) should
be avoided. For precise,spacial reproduction turn the speakers inside,directed to the hearing zone.

;Distance between speakers and your listening position a = 2 m … 5 m (6′7″ … 16′5″)
;Adjust the speaker horizontally to the height of the ear at the listening position

POSITIONING 8
musikelectronic geithain GmbH ME 160
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 … 5 m (6′7″ … 16′5″)
In case installation in the prescribed way is not possible in your listening room most decoding
devices allow adjustments of single speakers.

CONNECTING THE SPEAKERS 9
musikelectronic geithain GmbH ME 160
6 Connecting the speakers
Our passive speakers are no difcult load to common ampliers. An amplier power of 100 W … 400 W
at 4 Ω is suggested. Due to the linearized impedance the operation with tube ampliers is possible
without difculties. Your authorized ME Geithain dealer will gladly provide you with professional
advice.
6.1 Single-wiring connection
When connecting the speakers to an integrated amplier or a power stage check the connection for
the right polarity. The gold-plated screwed joints of the terminal are labelled with + and a -. Both
mustn’t be interchanged. Do not remove the bridges between the high and low frequency terminals.
6.2 Bi-wiring connection
In this case the high and low frequency crossovers are separately connected to your integrated
amplier or power stage. Remove the bridges between the high and low frequency terminals before
connecting the speakers to the amplier. Check the connection for the right polarity. The gold-plated
screwed joints are labelled with a + and a – and mustn’t be interchanged.
