BSX Operating Manual

Operating Manual for BSX
Introduction
Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.
The Big Subwoofer eXtender (BSX) is equipped with two powerful 21" drivers, with a
peak power of 10 kW per driver, this loudspeaker is able to reproduce an exceptionally
solid low frequency foundation. Thanks to the unique TW AUDiO hybrid enclosure prin-
ciple, maximum efficiency is achieved so that the acoustic energy is produced over a
greater distance than conventional subwoofers.
The BSX loudspeaker is primarily utilized as low frequency bass enhancement with
other subwoofer loudspeakers and can described as a ULF / Infra product. That said,
due to the BSX hybrid design and the extremely strong, yet light membranes, frequen-
cies up to 120 Hz are reproduced with exceptional transient response and in high fidel-
ity. This means the BSX loudspeaker can be operated in two modes or “Infra-bass/Ultra-
Low Frequency” or as a standard “Sub”. Therefore, it can also be combined directly with
the M, T, C or VERA systems.

Operating Manual for BSX
1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loud-
speakers.
The BSX loudspeaker was developed for professional use in sound systems. The loud-
speaker may only be used by trained and qualified personnel.
Note the operation modes described in this operating manual.
Other uses are not permissible.
TW AUDiO GmbH shall not be held liable for any damage that ensues from unintended
use.
WARNING
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not per-
mitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields
can cause pacemakers to malfunction.
WARNING
When working with heavy loads over 20 kg [44,09 lbs], use suitable aids (dollies, hoist-
ing slings, etc.). Multiple people may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loud-
speaker 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 appli-
cable safety regulations.
NOTE
When using the loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Moisture
• Jolting
•Dust
WARNING
Keep away from the immediate vicinity of loudspeakers that are operated at high sound
pressure levels. These loudspeaker systems are capable of endangering your health.
Sound levels beginning as low as approx. 90 dB SPL can lead to long-term hearing im-
pairment.
NOTE
Avoid:
• Feedback
• Distorted signals (clipping)
• Peaks that result when devices are switched on or hot plugged and unplugged.
These signals can lead to loudspeaker overload..

Operating Manual for BSX
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.
WARNING
Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may
cause a fire and result in serious property damage and personal injury.
NOTE
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 data carriers, EC cards
and CRT displays. A distance of approx. one meter is sufficient to avoid damage.
NOTE
Check loudspeakers and accessory parts regularly for visible wear. This is essential to
ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare
parts can be obtained from TW AUDiO.

Operating Manual for BSX
The BSX loudspeaker can be operated in two operation modes. The operation mode is
selected by choosing the preset in the system amplifier.
2.2.1. Full
Operation with Full Preset is recommended if the BSX loudspeaker is the only bass
loudspeaker used in the system.
2.2.2. Infra
Operation in Infra Preset is recommended if the BSX loudspeaker is used as an addi-
tional bass loudspeaker in the system for extending the lower limit frequency. In Infra op-
eration, the upper limit frequency of the loudspeaker is significantly lower than in opera-
tion with Full Preset.

4. Setting up the loudspeaker
The BSX loudspeaker is designed for upright and horizontal operation.
To connect the loudspeaker with an amplifier rack from TW AUDiO, proceed as follows.
The correct presets need to be selected for the cable connections.
TW AUDiO recommends operating the BSX loudspeaker on a DSP controller.
TW AUDiO only recommends using presets developed by TW AUDiO. The TW AUDiO
system racks are ideal for this purpose.
4.1 Setup
WARNING
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.
4.2 Connecting cables
NOTE
Please note that the parallel operation of several BSX loudspeakers is not recom-
mended by TW AUDiO due to the low impedance. This can cause damage to the loud-
speaker and amplifier.
NOTE
Ensure that the cable cross section is sufficiently large (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 the polarity (+/-) and pin as-
signment (1/2) are correct. Incorrect connection results in a significant change in the
loudspeaker sound characteristics and may damage the compression driver.
The pin connections of the BSX loudspeaker can be found in section 3.2 “Wiring dia-
gram” on page 5.
The total impedance of loudspeakers connected in parallel must not drop below the min-
imum operating impedance of the amplifier.
4.3 Operation
NOTE
Ensure that the right preset was selected before connecting the loudspeaker with the
amplifier.
Operating with an incorrect preset can damage parts of the loudspeaker.
NOTE
Ensure that the amplifier is properly sized according to requirements. Undersizing or
oversizing may damage the loudspeaker.
Please note the technical data in section 3.1 “Data sheet” on page 5.

5. Transport and storage
NOTE
As the BSX loudspeaker weighs over 100 kg [220 lbs], four people are needed to move
and transport the unit.
To transport the unit with a single person, TW AUDiO recommends using the wheels on
the rear of the unit.
When transporting and storing the unit, it is important to ensure that the finish 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 ade-
quately protect the sensitive speaker membranes.
In addition, appreciable dust deposits may considerably impair the functionality of a
loudspeaker 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 (Frontdolly)
• CoverBSX (protective cover)
The original packaging is unsuitable as permanent storage and transport packaging.
