Introduction
A desired child: the B18 loudspeaker.
Countless customer requests were the starting point for developing this loudspeaker.
Featuring a symmetrical bandpass design, our B18 sounds astonishingly controlled but also
very deep.
The fully symmetrical enclosure enables identical performance in all setup variants. In addi-
tion, directional sub arrays with partly reversed subwoofers are possible in all combinations
without restrictions – whether upright or crosswise, stacked on top of each other or side-by-
side. For simple and inconspicuous wiring of directional bass clusters such as these, the B18
provides two speakON® connectors on the front grill.

1. Safety | Intended use
The B18 loudspeaker was developed for use in professional sound systems. The loudspea-
ker may only be used by trained and qualified personnel.
WARNING
WARNING
WARNING
NOTE
NOTE
Avoid:
• Feedback
• Distorted signals (clipping) and
• Peaks resulting from switching on devices, plugging in devices or unplugging devices during
operation.
Such signals can lead to loudspeaker overload and ultimately to loudspeaker failure.
Keep away from the immediate vicinity of loudspeakers that are operated at high sound pres-
sure levels. These loudspeaker systems are capable of endangering your health. Sound levels
beginning as low as approximately 90dBSPL can lead to long-term hearing impairment.
When setting up loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Humidity
• Jolting
• Dust
When working with heavy loads exceeding 20 kg (44 lbs.), use suitable aids (dollies, hoisting
slings, etc.). Multiple persons may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loudspeaker can
result in serious personal injury and property damage.
When using and assembling TW AUDiO loudspeakers, only use materials specified by
TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable
safety regulations.
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permit-
ted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields can
cause pacemakers to malfunction.
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
Note the operating modes described in this operating manual. Other uses are not permis-
sible.
Damage caused by improper use is not covered by TWAMBO.

WARNING
NOTE
NOTE
Check loudspeakers and accessory parts regularly for visible wear. This is essential to ensure
continuing fault-free operation. Worn parts should be replaced immediately. Spare parts are
available from TWAUDiO.
A permanent magnetic field is present in the immediate vicinity of loudspeakers. Ensure that
objects which react sensitively to magnetic fields are not located in the immediate vicinity of
the loudspeaker. In particular, this applies to magnetic storage media, magnetic stripe cards
such as debit cards and CRT displays. A distance of approximately one meter is sufficient to
avoid damage.
Note that TWAMBO does not provide a warranty for damage that can be attributed to this type
of overload and therefore cannot be held liable for any secondary damage.
Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal over-
loads may cause a fire and result in serious personal injury and property damage.

WARNING
WARNING
WARNING
WARNING
The M20 pole mount flange (figure 2.1- item 2) is not designed for side forces once mounted
– do not apply any pressure from the sides.
Make sure that no external forces are applied to the system structures. No objects or persons
should lean against the structures, no objects should be thrown against them. If pressure is
applied on the flange the loudspeaker may be damaged or falling over.
Make sure that no unauthorized persons can access the system structures!
Cordon off the area professionally!
Make sure that the maximum load of 50kg / 110lbs for the M20 pole mount flange is not
exceeded! Figure 2.1 – Item 2.
For all system components mounted on top of the M20 pole mount flange, observe the res-
pective operating instructions!
Also be sure to observe all of the following warnings:
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!
Make sure the speakers are securely fastened to prevent personal injury and property damage.
Secure stacked loudspeakers properly so that they can be tipped by 10° in any direction
without toppling.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.

WARNING
Please note that only centered loads are allowed to be placed on the M20 pole mount flange
– Figure 2.1 – Item 2.
Make sure that the system structures are not operated over the audience at wind speeds in
excess of 6 bft (22 to 27 kn / 39 to 49 kph / 24.2 to 30.45 mph) and that there are no persons
in the immediate vicinity of the system structure!
Before setting up the system outdoors, consider unexpected wind conditions at the opera-
tion site!
Disassemble your system immediately when wind speeds exceed 8 bft (34 to 40 kn / 62 to
74 kph / 38.5 to 46 mph) and secure the system components!
Make sure that there are no persons in the immediate vicinity of the system structure!
