ACCESSORY KIET
5.1 Rigging structure KIBU
The rigging structure L-ACOUSTICS®KIBU is to be used solely for rigging with L-ACOUSTICS®KIVA and KILO
enclosures in vertical ‘‘Line Source’’ configurations.
The KIBU is provided with 2 shackles, each one has a safety cotter pin and can support up to 630kg (1388 lbs) with an
ultimate strength safety factor of 5:1. Using the provided shackles makes it possible to fly the KIVA system using 1 or 2
rigging point(s).
Figure 2: Rigging structure KIBU
KIBU is capable of rigging a maximum amount of weight of 266Kg / 586 lbs (in accordance with BGV-C1 standard).
According to the angle selected between each enclosure when installing the KIVA system, the mechanical stresses
within the system must be checked, so as to respect the following limits:
Up to 12 KIVA enclosures or 9 KILO enclosures or a maximum combination of 6 KIVA and 2 KILO
can be flown within any chosen angular configuration.
In order to use the KIVA system for up to 20 KIVA enclosures or 14 KILO enclosures or a maximum
combination of 12 KIVA and 4 KILO, the user must check that the system conforms to the
configuration chosen using SOUNDVISION simulation software
(see section ‘‘Mechanical Data’’ in the ‘‘SOUNDVISION’’ manual).
KIBU can also be used as a ground stacking platform for a configuration of standalone KIVA or KIVA and KILO
combination within the following limits:
A maximum of 4 KIVA or 2 KILO or a combination of the two is not to exceed a maximum of 0.78m
(30.7’’) in height if the KIBU is placed on the ground without securing it to the surface.
A maximum of 10 KIVA or 5 KILO or a combination of the two is not to exceed a maximum of
1.84m (72.4’’) in height when the KIBU is securly fastened to a surface.
It is the responsibility of the user to verify that the system is securely fixed to a stable flat surface and

5.2 Mounting accessory KIET
The mounting accessory L-ACOUSTICS®KIET is exclusively dedicated to support L-ACOUSTICS®KIVA and
KILO enclosures in a distributed configuration. It consists of the main part, called KIET, and a removable pole
adapter assembly.
The main part shown in Figure 3 is adapted for attaching both KIVA or KILO. It can be suspended from a structure or
ceiling (typically for use under-balcony with a KIVA enclosure for example). It is possible to secure the KIET to a
structure using three 10mm/0.4’’-diameter screws (not provided).
It is the sole responsibility of the user to verify that the KIET is correctly secured to the structure and
that its installation was performed by a trusted professional.
L-ACOUSTICS recommends securing to a concrete ceiling using expansion anchors designed to
support at least 5 times the total load of the system (the weight of the product is notated on the
identification label of each product).
The KIET is capable of rigging up to 2 KIVA enclosures or 1 KILO enclosure.
Figure 3: KIET main part for use under balcony
The pole adapter assembly is affixed to the KIET by four 8mm/0.3’’-diameter bolts. Using this attachment makes it
possible to adapt the KIET to a pole stand (35 mm / 1.4’’ diameter). These holes also mate to the OMNIMOUNT®

6.1 Rigging and Flying the Line Source Array (with KIBU)
Before installation, in order to position and correctly place the array the user will need to use L-ACOUSTICS®
SOUNDVISION software to determine:
•Correct hole position of the shackle on the KIBU
•Number of Loudspeakers KIVA and KILO
•Inter angle between enclosures for both KIVA and KILO
•Check of the system’s mechanical conformity
The rigging method for the KIVA system comprises the elements KIBU, KILO, and KIVA. Attaching one element to the
next is done using fully integrated components unique to each KIVA and KILO, there is no need for any other external
fastening accessory. Each loudspeaker incorporates two points in front that lock into the device above or below
depending on the configuration, and rear angle bar with an automatic release locking pin.
The following procedure will describe the method for a basic configuration (KIBU and a limited number of enclosures)
which will then be flown to accommodate more enclosures in the array.
6.1.1 Preparing to rig the KIBU to the first enclosure
To hang the first enclosure (KIVA or KILO) of the Line Source Array, the procedure is as follows (described here using
the KILO enclosure):
1. Position the shackle in the correct hole predetermined in the SOUNDVISION configuration. In the example
below, for the correct suspension point, the shackle is screwed in hole position ‘‘5’’ of the KIBU:
Figure 5: Rigging structure KIBU and its shackle with safety pin
The Shackle is provided
with a Safety cotter pin.

2. Attach the KIBU to the first loudspeaker in
the array. The example below describes
attaching to the KILO :
a. Bring the KIBU to the top of the
KILO by aligning the front connection
fittings slightly left on the joining
fittings on the enclosure.
b. Secure and lock the KIBU by sliding
it right towards the center of the
KILO enclosure enclosure until a
‘‘click’’ is heard.
Figure 6: Attaching the KIBU to the KILO
Verify that the automatic locking system at the front is fixed and correctly engaged, before KIBU is
attached to the rear angle bar, by moving it laterally. Also check that the front part of the KIBU
doesn’t shift when moving it up and down, an that the rear part can rotate freely:

Verify that the back of the enclosures are positively fastened by checking that each angle bar is
secured via the spring-loaded pin and that the pin is returned to the fully engaged position.
6. Continue to raise the assembly in order to attach the rest of the enclosures to complete the array.
Note: As the system is being raised, be sure to connect the appropriate speakon cables corresponding to the KIVA
or KILO in the configuration.
In using a combination of KIVA and KILO elements in a flown configuration the KILO enclosures
must always be positioned at the top of the array.
Never position KILO in between two KIVA enclosures.
6.1.4 Taking down the system
1. When lowering the system, position the lowest enclosure so that it is approximately 1.2m (4ft) above the ground (or
to a comfortable height which will allow the user to detach the bottom enclosure of the array).
2. Pull back the spring-loaded pin on the second to last KIVA in the array. It may help to slightly lift the bottom
enclosure, in order to release the angle bar located in the slot housing in back of the enclosure, then leave it loosely
hanging.
3. Gently lower the bottom enclosure until it comes to rest, secured only by the front points.
4. Replace the angle bar in the back of the bottom KIVA by pulling back the spring-loaded pin, placing the bar in the
center slot and releasing the pin so that it secures.
For the KILO enclosure the angle bar will be placed securely in the center slot of the enclosure and held in place
magnetically.
5. Standing in front of the array, position your hands to the front of the bottom enclosure in the array, place them
inside the grip handles. Release the locking mechanism with fingers on the right hand. The locking mechanism is
located within the right side grip on the enclosure. (The right side of the enclosure corresponds to the logo on the
front face).
6. Remove the enclosure by disengaging the locking mechanism and moving it laterally towards the right in order to
free up the bottom enclosure from the one above.
Make sure you have a firm grasp on the enclosure you are removing, because it will not be
connected to the array above nor will there be anything supporting it.
