Introduction
A sudden impact in depth paired with an exactly defined sound – this is what “bass” sounds
like.
The dimensions of our “smallest” let not assume such a performance. But the B10 wouldn’t
be a TW AUDiO sub if it hadn’t more to offer: Its newly developed long excursion cone driver
with an uncompromising 3“ dual voice coil and optional passive cross-over with switcha-
ble high-pass outputs enable the standard bi-amp mode amongst numerous other passive
applications:
One single B10 in stereo mode together with two C5 tops, two B10 switched to mono each
with one M8, or four B10 together with two M10, all variations powered by one standard
amplifier.

1. Safety | Intended use
The B10 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
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.
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.
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.

The standard version of the B10 loudspeaker is the B10A variant which can only be operated
in „ACTIVE“ mode. It comes with a standard connection panel. The separation takes place in
the amplifier DSP.
The B10P version can be used either passively (using the “MONO” and “STEREO” operating
modes) or active with the corresponding preset.
The integrated passive crossover (item 8 “Figure 2.1 - Overview” on page 7.) has three selector
switches that are described in the following chapter.

HINWEIS
If only single-channel cables (PIN 1+/-) are used, connect the left channel’s cable to the “Input”
connector. Connect the right channel’s cable to the “Reversed” connector.
If a four-pin cable is used for both channels (L = 1+/-, R = 2+/-), connect this cable to the
“Input” connector.
Never connect two amplifier channels to the “Input” and “Reversed” connectors using two
four-pin cables at the same time, as this may short-circuited and damage the amplifier.
The two vertical selector switches (see figure 3.2.3 - S1 and S2) activate the respective
high pass output. This makes it possible to connect and operate a mid/high range loudspe-
aker with a rated passive crossover of between 8 - 24Ohms on the TOP OUTPUT outputs.

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:
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
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.
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!

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 27kn / 39 to 49kph / 24.2 to 30.45mph) 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!

4.3 Operation
Operation of the B10A speaker requires a DSP-Controller. TW AUDiO recommends opera-
ting the B10P 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.
Please note the technical data in section 3.1 on page 11.
NOTE
NOTE
4.4 Connecting the cable
The pin connections of the B10 loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 11 and 12.
The internal wiring of the B10 loudspeaker allows for parallel connection of multiple loudspe-
aker units.
NOTE
To create a cable connection with an amplifier rack from TWAUDiO, 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.
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.

To enable a single person to transport several multiple B10 loudspeakers, TW AUDiO recom-
mends using the QDB10 quad dolly.
NOTE
5. Transport and storage
Due to the B10 loudspeaker weighing over 20 kg [44.09 lbs.], two persons are required to
handle and transport the unit.
• QDB10 (Quaddolly)
• BagB10 (Carrying bag)
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.
