2. Product Description
The subwoofer SONA SUB II is the ideal bass supplement for K&F SONA speakers. With its
discreet appearance, it fits in nearly any architecture. The practical mounting points with a
double keyhole design enable wall and ceiling installation. In addition to possible use with
the K&F Controller CD 44, it can also be operated with a universal electronic crossover. This
possibility makes it extremely attractive not only because of its convincing performance but
also economically. SONA-Lautsprecherserie

2.3 Required signal processor
The following information does not apply to the option "XO" :
When using the SONA SUB II, a signal processor is required such as an electronic crossover or
the K&F Controller CD 44.
The signal processor must provide at least the following settings:
• 1 x high-pass 4th order
• 1 x low-pass 4th order
• 1 x bell filter

3. Safety Instructions
3.1 Mounting the Speakers / Wall and Ceiling Installation
Warning
Suspended loads are safety related.
The speakers may only be mounted by qualified event technicians or personnel which are
instructed by them, adequately. This also applies for wall and ceiling fixations.
The technicians responsible for assembling the speakers on site are responsible for the safe
setup and use of the speakers and guarantee the safe use of the mounting elements.
Never use signal cables or power cords for suspending, aligning or securing the systems.
Before carrying through ceiling and wall installations, it is essential to consider the load
capacity, the stability and type of the construction of walls, ceilings and panelling. If there is
wall panelling, for example, it is then necessary to examine the solidity of the wall and use
the appropriate wall plugs.
Note that the suspension points on the hall ceiling (i.e. shackles, suspension points, or chain
points) must comply with the accident prevention regulation BGV C1 (Event and Production
Sites for Stage Presentations) or comparable applicable national standards, and the total load
must be approved by an authorised expert.
Make sure to comply with the stipulated tightening torques.
If not otherwise stated in this manual, only original KLING & FREITAG parts may be used for
mounting the speakers. The use of other parts – in particular parts by other manufacturers –
is not permitted in this case.
Ensure that all installation connections comply with the applicable safety guidelines and that
the size and strength are sufficient.
Ensure that all connections are secured against coming loose and that only authorized,
statically tested and correctly sized supports, mounting equipment, wire ropes and chains are
used.
As a basic principle, you must visually inspect all safety-relevant components of the speaker
and the accessory before every use. If there are signs of wear, cracks, or deformation, then
you must replace the parts immediately. The visual inspection also includes checking the
screwed connections on supporting elements.
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
3.2 Notes for Mounting the Speakers
Warning
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall.
Please note that speakers can move as a result of vibrations. To prevent them from falling
from their mounted position, they must be secured properly.
User's manual K&F SONA SUB II
KLING & FREITAG GMBH © 2014 Version 1.3 Page 7 of 19
When laying out the connecting cables, make sure that nobody can trip.
3.3 Preventing hearing damage
Caution
Avoid beeing too close to operating speakers. This equipment is capable of delivering sound
pressure levels in excess of 90 dB SPL, which may cause permanent hearing damage.
3.4 Protecting the Speakers / Operating Safety
In general, audio signals must not be overdriven. This may be caused by mixing consoles,
equalizers, effect equipment, etc. and should be indicated on this equipment. When a power
amplifier is overloaded at the output (clipping), then the amplifier should activate a clipping
warning signal. Power amplifiers can also be overloaded at the input circuit without the
amplifier signalling the clipping, i.e. when there is not sufficient headroom in the input
circuit. We, therefore, recommend turning up the power amplifiers all the way and adjusting
the level before the power amplifier in order to avoid overloading the input circuit. In any
case, the signal must be reduced as soon as it sounds unnaturally distorted.
Operations without CD 44 Controller (only option "XO"):
• To protect the speakers from being destroyed and to avoid fire hazard, they should
only be operated with professional power amplifiers with a maximum rated output
power of 150W@8Ohm.
• If power amplifiers have power ratings lower than 75W@8Ohm, then it is imperative
that the amplifiers have clipping limiters. Alternately, you can also insert a clipping
limiter before the amplifier.
• To achieve sensible acoustic results and to protect the speaker from mechanical
destruction during use, the speaker must be filtered according to this manual. See
chapter Configuration and Connecting Diagram from page 10.
Operations with CD 44 Controller:
• For optimal performance and operating safety of the SONA SUB II speakers we
recommend using the system controller K&F CD 44.
• When operating the loudspeaker with amplifers without clipping limiter and nominal
amplifier power less than 75W@8Ohm requires to set a Limit Reduction of 3dB for the
K&F CD 44 controller.
• The destruction of speakers and the risk of fire as a result of a very rare power
amplifier or speaker defect may not be avoided by the controller in any case.
For damage caused by
• overloading the speakers
• using power amplifiers with other than the recommended maximum output power
we do not assume warranty and excludes liability for possible consequential damage.
The following signals may damage the speakers:
• clipping power amplifiers
• permanent high-level signals with high frequency and continuous noise from feedback.
• permanently distorted high-level signals.
• noises, which occur when the amplifier is on while equipment is being connected,
disconnected or switched on.
Do not install devices in any of the following places:
• where the devices are permanently exposed to direct sunlight.
User's manual K&F SONA SUB II
KLING & FREITAG GMBH © 2014 Version 1.3 Page 8 of 19
• where the devices are exposed to high moisture or rain.
• where the devices are exposed to strong vibrations and dust.
Avoid damage caused by the speakers' magnetic fields
Speakers are permanently surrounded by a magnetic field, even when they are not
connected. Therefore, during transport and placement of the speakers, it is important to
ensure that there is a sufficient distance between the speakers and magnetic data media and
computer/video monitors (except flat panels).

4. Correct Ratio between Top and Bass Speakers
For a balanced sound reproduction, suitable for speech and average music material, one
subwoofer SONA SUB II can be combined with up to 4 tops SONA 5. This is valid as long as the
amplifiers for subwoofer and top skeakers have the same overall gain and the SONA SUB II is
mounted on a wall or on the open floor (reference use).
If more bass level is desired for DVD playback or reproducing very low-frequency signals (i.e.
motor sounds), then the subwoofer can used with 2 SONA 6 speakers or 1 SONA 8 speaker.
For this type of use, the subwoofer has to be used with filtering, since there is a risk of
mechanical otherwise. For maximum performance and operating safety, select use with the
CD 44. For maximum performance and operating safety, select use with the CD 44.
For an additional bass boost the level increase which occurs in room edges and room corners
can be used. The placement in room edges and room corners is also beneficial because of the
excitation of more room modes which results in a more even bass coverage across the room.
The correct loudness ratio between tops and bass is, therefore, very dependent upon the
bass’s setup location, the spatial geometry, the required playback material and, last but not
least, your personal preferences. For this reason, the ratio between tops and bass should
always be assessed on site, for example with a third-octave band analyser or a notebook with
corresponding measurement software.
4.1 Level increase because of adjacent areas
As shown in the following table, adjacent areas can lead to significant level differences.
Setup Location Name Level increase Pictogram
Freely suspended Free field (full
space) +/- 0 dB
On a surface
(Reference use) Half space ca. +3 dB to +6 dB
In a space
