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 801K1
3 System description
High level + large room = big loudspeaker? The ME 801K1 is about to rebut that. Longer reverb, larger
rooms and listening distances easily spoil the fun for the ambitious music listener. The ME 801K1
makes use of a few things out of the bag of tricks lled throughout the long history of the company
with much technical know how.
As well as the legendary RL 901K the ME 801K1 uses a 16-inch long-throw woofer. ME Geithain’s
typical cardioid dispersion behaviour in the lower frequency range from 25 Hz to 250 Hz minimizes
reections behind the speakers so positioning is less critical. A 6.5-inch high-performance midrange
cone driver and an array of three 1-inch dome tweeters are coaxially mounted in front of the low
range driver. This arrangement ensures the directivity that is needed in large rooms to minimize
reections and provides an irresistible spatiality. Their high sensitivity offer not only impressive level
and dynamic capabilities but also low distortion. The consequent use of the coaxial technology has
another undeniable advantage: the size of the speaker is obviously reduced. Thanks to housing the
amplier in its own cabinet the dimensions are further reduced. The electronic part consists of three
PWM ampliers and an analogue lter equipped with a room equalization lter to adjust the speaker
to the position in and the properties of the listening room. The ampliers deliver a power of 1000 W
in the low frequency channel and 500W each in the mid and treble channels. Therefore dynamical
limits of the whole system are no concern.
Despite all of these features the ME801K1 sticks to its roots and has all the virtues our customers
value: neutrality, homogeneity, low coloration and longevity.
An elegant stand for the ME801K1 is available upon request.

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 7

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.
The speakers ME801K1 however utilize cardioid radiation characteristics with rearward attenuation
greater than 10dB. Because of this structural measurement installation near walls is considerably
less critical. For optimum listening experience a minimum distance of 20 cm (7.9″) to walls and
furniture should be ensured. Avoid corner installations because unwanted bass accentuation could
arise.

POSITIONING 8

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 3 m (9′10″) or more than 6 m (19′8″)
should be avoided. For precise,spacial reproduction turn the speakers inside,directed to the hearing
zone.
