Introduction
So far the Big-Subwoofer-eXtender is the biggest TW AUDiO sub to date.
Equipped with two powerful 21“ drivers with a peak performance potential of 10kW per dri-
ver, this speaker is able to reproduce a truly massive bass foundation.
Thanks to the hybrid enclosure principle its efficiency is maximised so that the energy is still
perceptible even at a great distance. Primarily the BSX functions as a true sub bass exten-
sion.
Because of its extremely stiff yet lightweight membranes the BSX is able to deliver frequen-
cies of up to 120 Hz clean and true to its impulses. As a full range sub the BSX is directly
combinable with the M, T, C or VERA systems.

1. Safety | Intended use
The BSX 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 90dB SPL 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.

2.2 Operation modes
The BSX loudspeaker can be operated in two operation modes. The operation mode is selec-
ted by choosing the preset in the system amplifier.
2.2.1 Full
In full mode, the BSX has a higher upper cutoff frequency. This mode is recommended for
operating the BSX with tops only.
2.2.2 Infra
Infra operating mode is recommended when using the BSX loudspeaker in a system with addi-
tional subwoofers. In this mode, the lower cutoff frequency results in a bass range extension.

4.1 Setup
The BSX loudspeaker is designed for standing, vertikal and horizontal operation.
WARNING
4. Commissioning
WARNING
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.
Please note that setting up the system setups always requires two, preferably four persons!
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
Make sure that no unauthorized persons can access the system structures!
Cordon off the area professionally!
Any influences on your system setup, such as leaning against objects (or people) and flying
objects around, be refrained from!
NOTE
WARNING

NOTE
Use all four rubber feets and insert them into the corresponding millings for rubber feets on
the BSX loudspeaker.
Note that the four black dots represent the rubber feets on the upper loudspeakers and the
millings for rubber feets on the BSX loudspeaker.

4.2 Operation
Operation of the BSX speaker requires a DSP-Controller. For this purpose, only presets
developed by TW AUDiO are recommended. The TW AUDiO system racks are ideally suited
for this purpose.
Please note the technical data in section 3.1 on page 9.
NOTE
NOTE
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 TW AUDiO 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.
4.3 Connecting the cable
The pin connections of the BSX loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 9.
The internal wiring of the BSX loudspeaker allows for parallel connection of multiple loudspe-
aker units.
NOTE
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.
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.

4.5 Possible vertical system setups
4.4 Wind load
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!
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!
WARNING
WARNING
Additional loudspeakers can be placed on top of the BSX loudspeaker in standing, vertical
operation.
Secure the stacked loudspeakers professionally so that a danger of tipping over can always
be excluded under the given installation conditions and environmental parameters!
Make sure that the existing millings for rubberfeets (Pos.1 - figure 2.1) are used for a safe
stacking of the loudspeakers.
