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.

4.3 Operation
Operation of the B18 speaker requires a DSP-Controller. For this purpose, only presets
developed by TW AUDiO are recommended. The TWAUDiO system racks are ideally suited
for this purpose.
Please note the technical data in section 3.1 on page 8.
NOTE
NOTE
4.4 Connecting the cable
The pin connections of the B18 loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 8.
The internal wiring of the B18 loudspeaker allows for parallel connection of multiple loudspe-
aker units.
NOTE
HINWEIS
In Cardio Setup mode, the sound radiated toward the rear is reduced. Ensure that you have
selected the correct preset for this setup. Incorrect connection results in a significant change
in the loudspeaker sound characteristics and may cause damage.
To create a cable connection with an amplifier rack from TW AUDiO, proceed as follows.
Ensure that the cable cross sectional area is sufficient (at least 1.5 mm²) to avoid power losses.
TW AUDiO recommends using the loudspeaker cables available from TWAUDiO.
When connecting the cables to the loudspeaker, ensure that polarity (+/-) and pin assignment
(1/2) are correct. Incorrect connection can lead to a significant change in the loudspeaker’s
sound characteristics and may damage the driver.
Please note that parallel connections will decrease the total impedance of your loudspeaker
configuration.
The total impedance and the resulting power of the speaker configuration must match the
output power of the amplifier.
In Cardioid mode, the focus is on maximum sound pressure reduction behind the loudspeaker
setup, with partial forward-facing level addition.
The rear speaker produces an inverted signal to cancel out sound components on the back.
This results in a sound pressure level reduction of about 20 dB over a wide frequency range.
Depending on the distance between the loudspeakers and their transit time difference, there
will be a frequency-dependent sound pressure level addition of up to 3dB in front of the
loudspeaker arrangement. By adjusting the transit time difference between the two individual
drivers, a different dispersion pattern – e.g. hypercardioid – can be achieved.
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
loaded.
Using a wrong, out dated or a preset not provided by TWAUDiO can lead to destruction of
the speaker.
Make sure that the amplifier’s specifications meet the requirements. Using an amplifier that
doesn’t meet the specifications can destroy the loudspeaker.

5. Transport and Storage
To transport the unit with a single person, TW AUDiO recommends using the FDB18 front
dolly. Alternatively, up to four B18 loudspeakers can also be transported in a QDB18 quad
dolly.
NOTE
Due to the B18 loudspeaker weighing over 40 kg [88 lbs.], three persons are required to
handle and transport the unit.
• FDB18 (front dolly)
• QDB18 (quad dolly)
• CoverB18 (protective cover)
When transporting and storing the unit, it is important to ensure that the surface and front
grill of the loudspeaker are not damaged. Moisture can penetrate through exposed wood
surfaces and cause the wood to swell. A bent or broken front grill will no longer adequately
protect the sensitive speaker membranes.
In addition, appreciable dust deposits may considerably impair the functionality of a loudspe-
aker membrane. For this reason, the loudspeakers should be transported and stored in a
safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from TW AUDiO:
The original packaging is unsuitable as permanent storage and transport packaging.
