6. Mounting Instructions for Loudspeakers
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall. Speakers, which are stacked, must be se-
cured with securing straps. When laying the connecting cables, make sure that no-
body can trip.
The stability of stacked systems (also valid for the use of stands and distance rods!) is
contingent upon the following stability requirement. These conditions must, there-
fore, be guaranteed by the user:
Stacked systems may not fall over even if they are inclined by 10° in each
direction. If this requirement is not fulfilled, then it is necessary to take steps
to achieve compliance. Possible measures include strapping it to an appropri-
ate base structure or fastening it using safety straps.
6.1 Proper Arrangement of the Loudspeakers
Be aware of the fact that the logical targeted alignment of this high quality speaker
system can lead to a significant qualitative increase in the acoustic result. It is not
possible to make generalities about the alignment of specific systems because the
room has a substantial influence on the signal and the audible result.
As a rule, the mid- and high-transducers of loudspeakers should be mounted above
the audience's face value, so that the sound distribution cannot be shadowed.
In many cases it is advisable to mount a loudspeaker higher, so that the sound will be
distributed throughout the room more evenly. Low standing systems result in a
greater difference in volume between front and back seats than higher standing sys-
tem.
Please note that this is only a general guideline and the best possible result may vary
from room to room.
To simulate the correct alignment of the speakers beforehand, there are various pro-
grams such as ‘Ease’ or ‘Ulysses’. The Kling & Freitag speaker system data is available
for download on our website www.kling-freitag.de.
The following graphics will assist in making a rough estimate as to the distance range
of the E 90 MK II. The graphics only take into consideration the sum of the direct
sound and not the influence of the room. Because of this there can, in some cases, be
noticeable deviation.
