SYSTEM DESCRIPTION 3
musikelectronic geithain GmbH BASIS 11K BASIS 13K BASIS 14K
3 System description
BASIS 11K, BASIS 13K and BASIS 14K complement the lower octave of our active control speakers
aswell as the central bass unit for stereo playback. On request, the BASIS models with our
multichannel bass processor can also be integrated in surround loudspeaker systems. Furthermore,
the subwoofers can be operated with suitable AV receivers, so that an optimal interaction with our
passive high-end loudspeakers is possible.
We have developed special long-throw driver systems for our active bass speakers, which guarantee
a low-distortion reproduction. All BASIS models have a cardioid-shaped radiation pattern to minimize
backward room reections. Due to the so-called K-technology (cardioid radiation characteristics in
the bass range), which we have already been successfully using for many years with our 3- and
4-way active loudspeakers, the backward attenuation of more than 10dB can achieve excellent
results of the space-dependent transmission process even in acoustically critical rooms. As a result of
this design principle, the placement of the bass speakers in their listening room is greatly simplied.
The amplier output stages work with a 1000 W PWM power module. An electronic limiter acts
as a protection device and protects the low-frequency drivers against overloads. A rear-mounted
LED signals the response of the protection device and the operating state of the bass speaker. The
distance from the front speaker to the subwoofer can be 0m to 1 m. In this area, a phase correction
is possible. By a switchable high-pass lter, the lower frequency limit can be increased to 40 Hz. The
crossover frequency is continuously adjustable between 60 Hz and 80 Hz. The transmission range of
the LFE channel ends at 120 Hz. The entire control and power electronics as well as all plug-in and
control elements are integrated in the rear of the cabinet.
As an option, the bass speakers are available with a grille. An output on our subwoofers enables the
operation of another passive bass speaker BASIS11KP, BASIS 13KP or BASIS 14KP. This extension
realizes an acoustic performance doubling and makes the choice of the site less critical. Furthermore,
the system can be switched with a wired remote control in the bypass mode. All output channels
are connected directly to the input channels - the bass channel is disabled, the LFE channel remains
active.

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.

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
subwoofer behaves as a punctual sonic source, with sonic waves spherical radiated without any
constructional measures. Back wall reections are unavoidable.
The subwoofers BASIS 11K,BASIS 13K and BASIS14K however utilize cardioid radiation characteristics
with rearward attenuation greater than 10 dB. 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.

The distance of the BASIS 11K,BASIS 13K and
BASIS 14K should not exceed 1 m (3′3″) in the
direction of the listening zone to the plane
of the front speakers. A range adjustment is
provided for the devices in this range and can
be made on the adjustment knob (2) (see the
gure in chapter 6).
It is not necessary to place the subwoofers
exactly in the middle of the stereo base,since
locating the sound source below 100Hz is
only possible to a limited extent. But it should
always be on the same level between both front
systems. Placing the subwoofer outside the
stereo base may result in unwanted localization
of the BASIS 11K, BASIS 13K and BASIS 14K.
