1. Safety | Intended use
The B17i 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
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.
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 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.
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.
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.
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.

Before fitting the accessories follow the subsequent steps:
4. For the B17i loudspeaker M10 threaded insert, various TW AUDiO accessories can be
mounted. For each product refer to the instructions.
5. Note that the load capacity is limited to a single speaker.
3. Please note that once the countersunk screws are removed, water and moisture may
enter into the enclosure.
1. To remove the countersunk screws remove the texture paint by using a cutter knife. Avoid
damaging the surrounding paint to prevent chipping.
2. Remove for your application required countersunk screws. Use a hexalobular key with the
size of TX50.
NOTE
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.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.

The B17i loudspeaker is equipped as standard with the i-series screw terminal.
NOTE
NOTE
4.4 Operation
Operation of the B17i loudspeaker 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.
Please note the technical data in section 3.1 on page 8.
NOTE
NOTE
As options there can be mounted a panel with cable gland (CG-option) or a panel with two
built-in speakON® jacks (SO-option).
Furthermore, a blind cover option is available.
All connection options are only available in black colour.
More information about the different connection options can be found in the respective opera-
ting instructions in the download area on the homepage of TWAMBO.
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.
