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.

Figure 2.3.1 - Connection diagram B15P
2.3 Operation modes
In operation mode 1 „ACTIVE“, the internal passive crossover is switched out of the signal
path, and the separation of the loudspeakers must take place in the DSP of the amplifier. The
pin connection of the B15 loudspeaker is switched to pin 2+/-.
1. Set the upper switch to “OFF”! This must never be set to “ON” when no loudspeaker is
connected to the high-pass output!
2. Switch the bottom switch to ACTIVE mode.
3. Connect the amplifier to the “input” connector. Do not inadvertently connect it to the high
pass output!
WARNING
two amplifier channels / 4-wire speaker cable required
Pin 1+/- TOP speaker
Pin 2+/- B15 subwoofer
The top selector switch is used to activate the high-pass output. The bottom selector switch
is used to activate the passive crossover and changes the pin assignment of the connection
sockets.

In operation mode 2 „PASSIVE 1“, the B15 loudspeaker and other loudspeakers are operated
on the „link output“ output on pin 1+/-.
1. Set the upper switch to “OFF”! This must never be set to “ON” when no loudspeaker is
connected to the high-pass output!
2. Switch the bottom switch to „PASSIVE mode“.
3. Connect the amplifier to the “input” connector. Do not inadvertently connect it to the high-
pass output!
WARNING
one amplifier channel is required
Pin 1+/-B15+M15
Pin 2+/-free
Note that the total impedance may vary depending on the connected loudspeaker. See
“Connecting the cable” on page 18.
NOTE
Never change the operation mode while the loudspeaker is in operation. This may damage the
connected loudspeakers.
Operation mode 1 „ACTIVE“ additionally requires the correct preset at the amplifier.
