Introduction
Thank you for choosing a high-quality product “MADEIN GERMANY” from TW AUDiO.
The M12i is the installation version of the M12, a product proven over many years in countless
deployments in FOH, delay line and monitor applications. Using the same components as
M12, the M12i is the perfect adaptation of this speaker for installations.
The phase-aligned and frequency corrected passive crossover allows the M12i to be driven
even by standard linear amplifier without DSPpresets. For extended fullrange use, or in com-
bination with TWAUDiO subwoofers, there are dedicated presets available for Powersoft and
Lab.gruppen amplifier platforms.
The M12i is available in two dispersion patterns, 90° × 60° and 60° × 45° allowing it to be
integrated as well as possible in the space.
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 M12i 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.
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.

4.1 Setup
The M12i loudspeaker is designed for hanging, vertical and horizontal operation. TW AUDiO
provides a wide range of accessories to securely attach the loudspeaker.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
NOTE
Make sure the speakers are securely fastened to prevent personal injury and property damage.
WARNING
4. Commissioning
4.2 M10 threaded inserts
Before fitting the accessories follow the subsequent steps:
4. For the M12i loudspeaker M10 threaded inserts, various TWAUDiO 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!

4.4 Connection options
The M12i loudspeaker is equipped as standard with the i-series screw terminal.
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.
NOTE
More information about the different connection options can be found in the respective opera-
ting instructions in the download area on the homepage of TWAUDiO.
NOTE
4.3 Rotating the HF horn
With the factory default orientation of the M12i loudspeaker horn, the horizontal coverage is
90° and the vertical coverage is 60°. In some situations, it may be advantageous to change the
high frequency dispersion pattern. To adjust the dispersion pattern, the M12i loudspeaker’s
HF horn can be rotated. Proceed as follows:
1. Place the M12i loudspeaker on its back, with the speaker grille facing up. Make sure to
place the speaker on a clean, non-slippery surface.
2. To remove the front grill, a 3 mm Allen key is required. Loosen the two mounting screws at
the top and bottom of the speaker cabinet.
3. Loosen the four screws on the horn using a 3mm Allen key. Pull the horn with the compres-
sion driver up and out of the speaker cabinet.
4. Check the seal between housing and horn for correct fit.
5. Carefully turn the horn by 90° and re-insert the horn with the driver back into the recess.
Screw it to the housing and apply medium-strength thread-locking fluid.
6. Attach the grill using the screws provided.
