1. INTRODUCTION
Designed to be consistently unique like all the unique K-array products, the KX12 is a radical reinterpretation
of a traditional coaxial 12” speaker. Its compact shape and different accessories allow the KX12 to
perform as a powerful audio point source or as part of a line array.
When high pressure is needed in the foreground with a rapid depreciation once distanced from the
source, the KX12 can meet this demand to become one of the most useful tools for an installer. Similar
to the Firenze KH7, an asymmetric 100° by 30° horn with an adjustable orientation gives to the speaker
an added value providing two modes of coverage to choose from to meet the needs of different
installations.
Additionally, dedicated accessories assist in the set up of joining, flying and stacking the speaker, making
it a perfect line array component.
Its steel chassis offers maximum rigidity in a minimum size. The speaker delivers a continuous SPL
of 127 dB and has a frequency range of 120 Hz to 19 kHz and it is compatible with all K-array KMT
subwoofers.

4. SAFETY information
Warning: failure to follow these safety instructions could result in injury
or damage to the device or other property.
IMPORTANT SAFETY INSTRUCTIONS
• Read these instructions.
• Keep this instructions.
• Heed all warnings.
• Follow all instructions and keep all warnings.
• Only use attachments/accessories specified by the manufacturer.
•
se only with the cart, stand, tripod, bracket, or table specified by the manufacturer or
U
sold with the apparatus.
•
hen a cart is used, use caution when moving the cart/apparatus combination to avoid
W
injury from tipover.
• Avoiding hearing damage. Professional loudspeakers are capable of producing extremely high sound
levels and should be used carefully. Never stand close to loudspeakers driven at high volume. Set
the volume to a safe level. You can adapt over time to a higher volume of sound that over time
may sound normal but can be damaging to your hearing. Hearing loss worsens after exposure to a
sound level of 90 dB or over for an extended period of time. If you experience ringing in your ears
or muffled speech, stop listening and have your hearing checked. The louder the volume, the less
time is required before your hearing could be affected.
• C
hoking Hazards. This device contains small parts, which may present a choking hazard to small
children. Keep the device and its accessories away from small children.
• D
o not make repairs yourself. Never attempt to disassemble, repair or modify the system yourself.
Disassembling the unit may cause damage that is not covered under the warranty. The device contains
no user-serviceable parts. Repairs should only be performed by factory trained service personnel.
• S
ound distortion. Do not operate speakers for an extended period of time with sound distortion. This
is an indication of malfunction, which in turn can generate heat and result in a fire.
• C
arrying, handling and installing the device. The device contains sensitive components. Do not drop,
disassemble, open, crush, bend, deform, puncture, shred, incinerate, paint, or insert foreign objects
into it. If your device has been dropped or damaged, unplug the power cable immediately.
• S
etup. Set up your device on a stable, horizontal surface. If combined or mechanically connected with
other products, always verify the stability of the resulting system. Install the unit only in a location
that can structurally support the weight of the unit and far away from interference with the stability
of the system. Ensure the wind does not interfere with the system’s stability, taking extra securities
such as chains, weights, ropes or any other certified anchoring systems. Otherwise a unit could fall,
causing property damage, personal injury or even death. The system should only be suspended by
qualified personnel following safe rigging practices. Securing fixtures to the building structure are
vital. To clarify any doubts you may have, seek help from architects, structural engineers or other
specialists.

5. UNPACKING
Each K-array speaker is built to the highest standard and thoroughly inspected before leaving the
factory. Upon arrival, carefully inspect the shipping carton, then examine and test your new amplifier.
If you find any damage, immediately notify the shipping company. Only the consignee may institute a
claim procedure regarding the system’s electronic equipment.

7. wiring
KX12’s internal wiring is designed to pick up the audio power signal from pins 1+ / 1- of a Speakon NL4
connector. Pins 1+ and 1-, such as pins 2+ and 2-, are directly wired from one socket to the other, so that
the two sockets are equivalent and can connect the speaker to the amplifier or to another KX12 driven
in parallel by the same amplifier channel.
NOTE:
The K-array KA84 amplifier can drive up to two KX12 units per channel

8. horn orientation
The KX12 features a 12” woofer and a compression driver coupled to an asymmetric horn. Because
the horn is asymmetric, its sound dispersion pattern is different in respect to its axes: the sound
dispersion is wide along the axis labeled FLOOD and narrow along the axis labeled SPOT.
The horn can be manually rotated 90° using the two handles situated at the front.
In this position the sound dispersion
pattern is wide (FLOOD - 100°) in the
horizontal plane and narrow (SPOT - 30°)
in the vertical plane.
In this position the sound dispersion
pattern is narrow (SPOT - 30°) in the
horizontal plane and wide (FLOOD - 100°)
in the vertical plane.
TIP
If you connect more units together to form a vertical array, make sure
to orient all horns in vertical (above picture on the left) so that they
are aligned in the same direction of the array. This will assure a wide
horizontal coverage with a narrow vertical dispersion.

9. RIGGING
K-array offers a variety of dedicated accessories to mount and connect the KX12 speakers for a wide
range of applications.
This section highlights the main accessories available for this product.
9.1 suspending the KX12 with a fly bar
KX12 units can be suspended using the K-FLY2B, a fly bar; K-FLY22, hardware used to connect the first
unit to the fly bar; and K-JOINT2B, the hardware that connects a KX12 to the K-FLY22 or to another
KX12.
K-FLY2B
K-FLY22
K-JOINT2B
1. First connect the two parts of a K-JOINT2B to each speaker with the provided 5x16 screws.

2. J oin the K-FLY2B and the K-FLY22 with the two 8x40 piston pins provided with the system.
3. C
onnect the first KX12 unit to the fly bar. Secure with the two 8x40 piston pins provided with the
system.
10
KX12
Ver. 1.5
4. Insert two joint blocks and secure each of them with the two 5x30 piston pins provided with the
system. The orientation of the joint blocks and the holes used will affect the angle between the fly
bar and the KX12, as shown below. We recommend setting an angle of 0° between the fly bar and
the first KX12 unit.
The pictures below show how to regulate the angles
If you want to angle the speaker by 0°, +5°, +10° or +15°, position the joint block so that the
letter “A” is at the bottom. Plug a piston pin in the hole labeled “A”, adjust the angle of the
speaker and plug the second piston pin in the hole corresponding to the desired angle.
If you would like to angle the speaker by -5°, -2.5°, +2.5° or +7.5°, position the joint block so
that the letter “B” is at the bottom. Plug a piston pin in the hole labeled “B”, adjust the angle
of the speaker and plug the second piston pin in the hole corresponding to the desired angle.

5. Repeat Steps 4 and 5 to add the other units.
The pictures below show how to regulate the angles
If you want the to angle the speaker by 0°, +5°, +10° or +15°, position the joint block so that
the letter “A” is at the bottom. Plug a piston pin in the hole labeled “A”, adjust the angle of
the speaker and plug the second piston pin in the hole corresponding to the desired angle.
If you want the to angle the speaker by -5°, -2.5°, +2.5° or +7.5°, position the joint block so
that the letter “B” is at the bottom. Plug a piston pin in the hole labeled “B”, adjust the angle
of the speaker and plug the second piston pin in the hole corresponding to the desired angle.
