Stacking a SB18i/KARAi mixed array or a SB18i standalone array

6.4.1

Modeling and safety

A SB18i/KARAi mixed array or a SB18i standalone array must be stacked directly on the ground (ground stacked
array).
Any SB18i/KARAi ground stacked array must be modeled before installation so as to ensure acoustical conformity.
This can be done using L-ACOUSTICS
 Determine the number of required KARAi enclosures (acoustic data not available for subwoofers).
 Calculate the inter-enclosure angles.
A ground stacked array requires to be installed on a perfectly plane and horizontal surface. It can be
composed of a maximum of 4 SB18i/9 KARAi or 8 SB18i enclosures within the setup safety limits given in
Table 2 regarding the angle between the top SB18i and the bottom KARAi (refer to [9.2.2] to obtain the
array site angle corresponding to the chosen angle value):

Array assembling procedure

The following procedure describes how to assemble and stack a vertical SB18i/KARAi mixed array or a vertical SB18i
standalone array.
All along the procedure:
Strictly follow the sequence of the successive steps.
Systematically verify that each bolt and screw is fully driven to the torque value given in this manual.
WARNING
For clarity purposes:
The loudspeaker cabling procedure will not be described.
The loudspeaker cables will not be represented on the figures.
CAUTION
Required components and tools
Electric screwdriver with torque selector (N.m or in.lb
bars and four M6 washers (for mixed arrays).
