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.

POSITIONING 7
musikelectronic geithain GmbH BASIS 11K BASIS 13K BASIS 14K
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.

6 Set-up the speakers
In this chapter we inform you how to connect your subwoofer to mains and your signal source and
how to connect the subwoofer to your active RL or MO speakers. Ensure that the mains switch
(12) on the backside is in position “OFF”. Only when your speaker is completely connected (see
chapters 6.1 and 6.2) you can take the device into operation by use of the mains switch.
The speaker can be connected to every common pre-amplier (Ua= 1 V ... 5V; Ri < 600 Ω).

6.1 Mains connection
Before start-up check the mains voltage stated on the backside of the device (14). If your local
mains voltage does not match the specication of the speaker,please refer to your retailer or direct
distribution. When the stated and your local mains voltage comply connect the mains connector of
the speaker to the socket (13) with the included mains cable.
6.2 Cable connection
The input of the integrated amplier is electrically balanced. When your signal source also utilizes
balanced connectors, please use a cable wired as stated in the table:

Earth Pin 1 Pin 1 Ring
Signal + Pin 2 Pin 2 Tip
Signal - Pin 3 Pin 3 Ring
When using a signal source with unbalanced outputs (RCA) you need to balance the connecting
cables. This avoids hum and other noise interferences. The table and the following gure show the
wiring.
6.3 Status indication
The two-coloured LED at the back of the speaker is used as status indicator of the device.
;LED green: indicates normal operation of the device
;LED red: indicates the operation of the overload protection circuit;

6.4 LFE connection
The LFE input of the BASIS11K,BASIS 13K or BASIS 14K is used to reproduce the LFE signal or to
use them as subwoofers. Use the the LFE output of your signal source and connect it to the LFE
input at the subwoofer (7).

6.5 Integration into stereo or surround speaker systems
For stereo or multi-channel operation,the channels connected to the BASIS11K,BASIS 13K or
BASIS 14K will pass through the active crossover of the subwoofer. Here,the bass frequencies of
the signals are ltered and played back via the bass system. The main and surround speakers are
relieved in the bass range.
For stereo operation,the left and right channels of your audio source are connected to the input
jacks CH1 and CH2 on the BASIS 11K, BASIS 13K or BASIS 14K (7). Connect the speakers of the two
stereo channels to the output jacks CH1 and CH2 (8). Please note that the inputs and outputs CH1
and CH2 are not interchanged when connecting to each other. The following table shows a circuit
example for stereo operation:
Input(fromsignalsource) Output(tothespeakers)
CH1 Front left Front left
CH2 Front right Front right
If you want to integrate your subwoofer into surround speaker systems,please use our multichannel
bass processor BCU 7.1. Connect the device to the MPI socket (9) on the BASIS 11K,BASIS 13K or
BASIS 14K using the cable supplied with the BCU 7.1. The device can control up to 7 channels. The
BCU 7.1 is not included but can be ordered from your dealer.
6.6 Bass extension
Our subwoofers BASIS 11K,BASIS 13K and BASIS 14K enable the parallel operation of other BASIS
models. The bass extension results in an acoustic doubling of performance and a more even sound
eld distribution, especially in acoustically less attenuated rooms.
The extension can be realized with our active bass systems BASIS11K,BASIS 13K and BASIS 14K as
well as with the passive subwoofers BASIS11KP,BASE 13KP and BASIS14KP. The passive subwoofer
can be connected to its active BASIS11K,BASIS 13K or BASIS 14K via a Speakon input on the rear
panel.
For parallel operation of a second active BASIS model, the LFE output (8) is provided on the amplier
unit. With this option,the second subwoofer can be controlled separately. For bass extension with
a passive woofer please use the Speakon output (11). The room acoustics adjustment of the
BASIS 11KP,BASIS13KP and BASIS 14KP are is carried out via their central bass unit. The maximum
power of 1000 W of the active BASIS model will in this case be split between the two subwoofers.
6.7 Remote switch
The remote switch is not included as the controller is not required for normal operation. You can
order this from your dealer. The switch is only needed if a playback of the program material without
bass support is provided. Turning on the controller will directly connect the stereo speakers and,if

SET-UP THE SPEAKERS 12
musikelectronic geithain GmbH BASIS 11K BASIS 13K BASIS 14K
the multichannel bass processor is used,the center and surround speakers,and mute the subwoofer.
For this use case the connector (10) is provided.
6.8 Using big main speakers
For large main speakers,the BASIS 11K,BASIS 13K or BASIS 14K should be used exclusively for the
subwoofer channel (LFE). The connection of the individual speakers to the subwoofer is therefore
not advisable,as an additional bass reproduction,in addition to the large main speakers,serves no
purpose.
6.9 Acoustical room adjustment of the subwoofer
After the subwoofer is properly positioned and connected, the volume (5) will be adjusted to that
of the main speakers. Then adjust the volume of the additional LFE channel (subwoofer) (4). We
recommend gradual adjustment of the level. As an advantage start this procedure with stereo mode.
Usually listeners have the most listening experiences in this mode,so that they react very sensitively
to errors in the sound image.
In case it was not possible to place the BASIS11K,BASIS 13K or BASIS14K at the same level as the
stereo speakers, please use the “Distance” knob (2) to correct the distance (see chapter 5.2). Please
note that the maximum correction for the distance of the subwoofer to the level of the front speakers
(in the direction of the listening zone) is 1 m.
On delivery,the fu switch (lower limit frequency) is set to 25 Hz. If you require a higher overall level,a
lower limit frequency of 40 Hz may be useful (1). This adjustment applies when using the subwoofer
as the central bass unit in stereo or surround mode, as well as in LFE mode. Via the controller (3)
you can adjust the crossover frequency between 60 and 80Hz. This setting is possible when using
the subwoofer as the central bass unit. By default,we recommend a crossover frequency of 80Hz.
The optimum range should be set by acoustic measurements. The upper limit frequency of the LFE
channel is not adjustable and is 120Hz.
For studio applications with reference status,professional measurement in the control room is
appropriate.
