SAFETY INSTRUCTIONS
1. Read this manual
2. Heed all SAFETY INSTRUCTIONS as well as DANGER and O LIGATION warnings
3. Never incorporate equipment or accessories not approved by L-ACOUSTICS
®
4. Read all the related PRODUCT INFORMATION documents before exploiting the system
The product information document is included in the shipping carton of the related system component.
5. Work with qualified personnel for rigging the system
Installation should only be carried out by qualified personnel that are familiar with the rigging techniques and safety
recommendations outlined in this manual.
6. Ensure personnel health and safety
During installation and set-up personnel must wear protective headgear and footwear at all times. Under no
circumstances personnel is allowed to climb on a loudspeaker assembly.
7. Respect the Working Load Limit (WLL) of third party equipment
L- COUSTICS
®
is not responsible for any rigging equipment and accessories provided by third party
manufacturers. Verify that the Working Load Limit (WLL) of the suspension points, chain hoists and all additional
hardware rigging accessories is respected.
8. Respect the maximum configurations and the recommended safety level
For safety issue, respect the maximum configurations outlined in this manual. To check the conformity of any
configuration in regards with the safety level recommended by L- COUSTICS
®
, model the system in
SOUNDVISION and refer to the warnings in Mechanical Data section.
9. e cautious when flying a loudspeaker array
lways verify that no one is standing underneath the loudspeaker array when it is being raised. s the array is
being raised, check each individual element to make sure that it is securely fastened to the adjacent element.
Never leave the array unattended during the installation process. s a general rule, L- COUSTICS
®
recommends
the use of safety slings at all times.
10. e cautious when ground-stacking a loudspeaker array
Do not stack the loudspeaker array on unstable ground or surface. If the array is stacked on a structure, platform,
or stage, always check that the latter can support the total weight of the array. s a general rule, L- COUSTICS
®
recommends the use of safety straps at all times.
11. Take into account the wind effects on dynamic load
When a loudspeaker assembly is deployed in an open air environment, wind can produce dynamic stress to the
rigging components and suspension points. If the wind force exceeds 6 bft (Beaufort scale), lower down and/or
secure the loudspeaker array.

SYSTEM
The system approach developed by L- COUSTICS
®
consists in providing packaged solutions for loudspeaker system in
order to guarantee the highest and most predictable level of performance at any step: modeling, installation, and
operation. n L- COUSTICS
®
loudspeaker system is the set of components available to form any loudspeaker system
based on one of the full-range loudspeaker enclosure afforded by L- COUSTICS
®
. It includes enclosures, rigging
accessories, loudspeaker cables, amplified controllers, and software applications.
The SB18m subwoofer is especially adapted to the RCS
®
WIDE SYSTEM or RCS
®
FOCUS SYSTEM, and to the
coaxial XT enclosures from L- COUSTICS
®
. It extends the low frequency response of a loudspeaker system down to
32Hz.
The main components involved in the S 18m rigging process are the following:
1.1 Loudspeaker enclosure
SB18m Subwoofer enclosure
provided with 2 SB18MRIG coupling bars equipped with the LOCKT B locking tab
1.2 Rigging elements
WIFOBUMP Frame for flying SB18m or RCS
®
WIDE/FOCUS enclosures as a vertical array

2.1 Maximum configurations
The SB18m rigging system has been designed to comply with BGV-C1 (2012) and EN ISO 12100-1 (2004) when
implementing the following vertical arrays:
Ground-stacking Flying
On the floor
8 SB18m
With WIFOBUMP
8 SB18m
With WIFOBUMP and CL MP250
4 SB18m
Mechanical safety of the shackles
The bow shackles Ø12mm provided by L- COUSTICS
®
have a working load limit (WLL) of 1000 kg with a 6:1
safety factor. This rating is in in accordance with BGV-C1 (2012) recommendations when implementing the
maximum configurations authorized by L- COUSTICS
®
.
Mechanical safety
of the rigging system
Maximum configurations indicate the maximum number of enclosures which can be safely arrayed without the
need for SOUNDVISION modeling. For more enclosures, model the system in SOUNDVISION and check
the Mechanical Data section for any stress warning or stability warning.
2.2 Assessing mechanical safety
In order to assess the actual safety of any array configuration before implementation, refer to the following warnings:
Rated working load limit (WLL) is not enough
The rated WLL is an indication of the element resistance to tensile stress. For complex mechanical systems
such as loudspeaker arrays, WLLs cannot be used per se to determine the maximum number of enclosures
within an array or to assess the safety of a specific array configuration.
Mechanical modeling with SOUNDVISION
The working load applied to each linking point, along with the corresponding safety factor, will depend on
numerous variables linked to the composition of the array (type and number of enclosures, splay angles) and
the implementation of the flying or stacking structure (number and location of flying points, site angle). This
cannot be determined without the complex mechanical modeling and calculation offered by SOUNDVISION.
Assessing
the safety
with SOUNDVISION
The overall safety factor of a specific mechanical configuration always corresponds to the lowest safety factor
among all the linking points. lways model the system configuration with the SOUNDVISION software and
check the Mechanical Data section to identify the weakest link and its corresponding working load. By
default, a stress warning will appear when the mechanical safety goes below the recommended safety level.
Safety of ground
-
stacked
arrays in SOUNDVISION
For ground-stacked arrays, a distinct stability warning is implemented in SOUNDVISION. It indicates a
tipping hazard when the array is not secured to the ground, stage or platform. It is user responsibility to
secure the array and to ignore this warning.
Consideration must be given to unusual conditions
SOUNDVISION calculations are based upon usual environmental conditions. higher safety factor is
recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to
salt water, etc. lways consult a rigging specialist to adopt safety practices adapted to such a situation.

This document only deals with independent rigging of the SB18m subwoofer enclosure.
When using the SB18m enclosure as a companion to a main system, some combined configurations will imply
the set-up of mixed arrays. t this point, it is especially the case of RCS
®
WIDE/SB18m or

FOCUS/SB18m arrays. lways refer to the rigging manual of the main system or enclosure to get
acquainted with the rigging procedures specific to the mixed main/sub arrays.

3.2 Flying
Never implement a bridled suspension on the WIFO UMP frame.
Always use 1 motor per pick-up point.
Truss clamping
By installing a CL MP250 instead of a shackle, an array can be attached to a truss. Refer to PROCEDURE .
Final check before flying the system
Coupling bars: ll lugs of locking tabs must be secured, as indicated in PROCEDURE A.
Shackles : ll safety pins must be secured as indicated in PROCEDURE .
Choose the flying option before rigging the system
Identify the appropriate flying option and rigging hole(s) by modeling the system in SOUNDVISION.

PROCEDURES
A. Locking a S 18MRIG bar
Coupling bars and S 18m
For SB18m/SB18m or SB18m/WIFOBUMP attachment, only use the long SB18MRIG bars stored on the
SB18m subwoofers. The shorter WIFORIG bars cannot ensure the mechanical safety of these connections.
 RIGGING: Slide the bar into adjacent rigging rails from the front of the array.
STORAGE: Engage the bar into both storage pins.
 Secure the bar with the locking tab.
a. ccurately position the bar by pushing it into place.
b. Pinch the spring tongue and slide the locking tab until it snaps into place.
When encountering difficulty, try to slide the tab from the other side.
