Each position of the aeronautic specified cargo restraint track has a maximum load capacity of 180kg, 
considering the enclosure is correctly flown, as shown in the diagrams. 
 
The tracking system works in combination with Ecler ADP cargo restraint double stud and ring. (Adam 
Hall Ref. 5740) 
 
The total load capacity of the structure is limited by this track and is 180kg per anchor point. (360kg 
total) 
 
It is very important to keep in mind that these values are only valid if the load is suspended 
perpendicularly. Load capacity varies as a function of the angle according to following table: 
 
 

 
 
 

 
Always make sure that the anchor points are firmly attached 
to the rail and locked. 
 
 
7. CONFIGURATIONS 
 
Many aspects have to be considered when deciding the optimal electroacoustic reinforcement design for 
a given space. All those aspects interact with each other, complicating the design stage even further. 
More than a “cookbook” on sound system design and installation, this chapter describes several factors 
which must be considered, as well as some guidelines which may help you to take the right decisions. 
 
Unfortunately, acoustic principles are too often in conflict with aesthetic criterions. PA system designers 
must admit and accept that the aesthetics of loudspeaker enclosures, in particular those designed for 
high pressure levels, is not easily compatible with most designs. As a general rule for this kind of 
situation it is recommended to find a single central sound radiation point. Ideally this would be done with 
one single loudspeaker, but in practice, clusters or  arrays including several more or less overlapping 
loudspeakers must be used, according to the coverage and sound pressure requirements. 
 
The first point to consider when deciding the location of the loudspeaker enclosures is the load capacity 
of the suspension point. Secondly, the spot must be easily accessible for installation and later 
maintenance tasks. On third place, the distance from the amplifier racks should be as short as possible, 
and last but not least, acoustic design goals should be achieved. 
 
The configuration you choose should basically depend on the desired SPL at the farthest audience point 
and the required coverage width, while offering good frequency response characteristics. If the 
efficiency of one loudspeaker is not enough to deliver a  certain SPL at a given distance, more 
enclosures must be aimed at that spot. The acoustic wave “beams” of the speakers can overlap more or 
less, obtaining a maximum overlap if the enclosures are mounted parallelly, one on top of the other. 
 
At the end of this manual you will find the polar diagrams for different cluster structures, both for the 
horizontal and vertical planes. The diagrams show the coverage angle and relative on-axis SPL 
compared to one single speaker enclosure. The table includes results for clusters of 1 to 6 horizontally 
and 1 to 2 vertically arranged enclosures, with aperture angles of 12

°

 (side-to-side) and 32

°

 
The enclosures are stacked together with minimum separation. The results are valid for the specified 
frequencies. They are not valid for set-ups which include the CKL SM115 bass reinforcement enclosure.
