Introduction
Thank you for choosing a high-quality product “MADEIN GERMANY” from TW AUDiO.
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.
If you lend your product to another party, inform that party of the safety-related operating pro-
cedures and hand over this assembly guide. If you require additional copies of this manual,
you can obtain them free of charge from TW AUDiO or download them from www.twaudio.de

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
The BSX 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 TW AUDiO 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

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 TW AUDiO 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 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.
Make sure the speakers are securely fastened to prevent personal injury and property damage.
WARNING
4. Commissioning
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!
WARNING

4.2 Operation
Operation of the BSX 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.
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 9.
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 TWAUDiO preset can destroy the speaker.
NOTE

4.3 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 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.
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

5. Transport and Storage
To transport the unit with a single person, TWAUDiO recommends the storage on the back
rollers.
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:
• FDBSX (front cover)
• CoverBSX (protective cover)
The original packaging is unsuitable as permanent storage and transport packaging.
NOTE
Due to the BSX loudspeaker weighing over 100 kg [220.46lbs.], four persons are required to
handle and transport the unit.
