Introduction
Thank you for choosing a high-quality product “MADEIN GERMANY” from TW AUDiO.
Our B15 loudspeaker is a true multi-talent, especially with the optional passive crossover
PWB15. The 1× 15“ fitted bass reflex system is suitable for the switchable bi-amp mode or
as a passive bass extension for our M and C series loudspeakers.
The passive crossover has a satellite output with a switchable high-pass filter. This enables
the B15 loudspeaker to be passively used without additional system controllers together with
various 8 ohm loudspeakers with one standard amplifier.

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
The B15 loudspeaker was developed for use in professional sound systems. The loudspea-
ker may only be used by trained and qualified personnel.
Note the operating modes described in this operating manual. Other uses are not permis-
sible.
Damage caused by improper use is not covered by TW AUDiO.
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.
When working with heavy loads exceeding 20kg (44,09 lbs.), use suitable aids (dollies, hois-
ting 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 TWAUDiO loudspeakers, only use materials specified by
TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable
safety regulations.
WARNING
When setting up loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• direct sunlight
• Humidity
• Jolting
• Dust
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.
WARNING
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.
WARNING
NOTE
NOTE

Operation manual B15

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
Note that TWAUDiO 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.
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.
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.

2.2 Variants
The B15 loudspeaker comes in two different variants. These variants are the B15A (ACTIVE
model) and B15P (PASSIVE model).
2.2.1 B15A/B15P models
The standard model of the B15 loudspeaker is the B15A variant, which can only be operated
in the „ACTIVE“ operating mode. It is supplied with a standard connection panel. The separa-
tion occurs in the DSP of the amplifier.
The B15P model can also be operated in the „PASSIVE 1“ and „PASSIVE 2“ modes. This
permits the connection of an additional loudspeaker on the high-pass output or the link out-
put when operating with only one amplifier channel. The installed passive cross-over (pos.10
“Figure 2.1 - Overview” on page 7) has two selector switches, which are described in the
following section.

4.1 Setup
The B15 loudspeaker is designed for standing operation.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
NOTE
Ensure that the loudspeakers are securely attached to prevent personal injury and prop-
erty damage. Secure stacked loudspeakers properly so that they can be tipped by 10° in
any direction without toppling.
WARNING
4.2 M20 pole mount flange
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!
WARNING
Make sure that the maximum load of 50kg / 110lbs for the M20 pole mount flange is not
exceeded! Figure 2.1 – Item 3.
WARNING
Make sure that no unauthorized persons can access the system structures!
Cordon off the area professionally!
WARNING
The M20 pole mount flange (figure 2.1- item 3) 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 per-
sons should lean against the structures, no objects such as balls should be thrown against
them. If pressure is applied on the flange when mounted the loudspeaker may be damaged
by falling over.
WARNING

4.3 Operation
Operation of the B15A speaker requires a DSP-Controller. TW AUDiO recommends opera-
ting the B15P loudspeaker on a DSP-Controller. For this purpose, only presets developed by
TW AUDiO are recommended. The TWAUDiO system racks are ideally suited for this purpose.
Make sure that the amplifier’s specifications meet the requirements. Using an amplifier that
doesn’t meet the specifications can destroy the loudspeaker.
Please note the technical data in section 3.1 on page 12.
NOTE
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
loaded.
Using the wrong preset or a preset not provided by TW AUDiO preset can destroy the speaker.
NOTE

Operation manual B15
18
4.4 Connecting the cable
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 TW AUDiO.
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.
The pin connections of the B15 loudspeaker can be found in section 3.2 (“Connectiondia-
gram”) on page 13.
The internal wiring of the B15 loudspeaker allows for parallel connection of multiple loudspe-
aker units.
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.
NOTE

Operation manual B15
19
To transport the unit with a single person, TWAUDiO recommends using the FDB15 front
dolly.
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:
• FDB15 (front dolly)
• CoverB15 (protective cover)
The original packaging is unsuitable as permanent storage and transport packaging.
NOTE
5. Transport and storage
Due to the B15 loudspeaker weighing over 20kg [44.09 lbs.], two persons are required to
handle and transport the unit.
