C15 Operating Manual
Introduction
Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.
The C15 is a coaxial loudspeaker utilizing a mid/high frequency driver with 3" mem-
brane/voice coil and the large 1.4" horn design ensures perfect dispersion characteris-
tics.
The C15 also incorporates a switchable passive crossover allowing for bi-amp or pas-
sive drive whilst maintaining phase-coherency between all speaker elements eliminating
the need for additional processing. Due to the very low crossover frequency of the mid/
high frequency driver, the C15 loudspeaker sounds even more direct in the vocal range.
The C15 is primarily designed as a floor monitor wedge yet is equally adept as a full-
range loudspeaker as rotatable horn, pole mount, multiple handles flyware/rigging points
and well positioned SpeakOn®sockets are all included on the product.
The C15 loudspeaker is recommended for all applications and offers clarity and control
in a compact format.

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loud-
speakers.
The C15 loudspeaker was developed for use in professional 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..

C15 Operating Manual
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.

2.2 Operation modes
The C15 loudspeaker has a selector switch (in the side
recess of the connection panel) for switching between two
different operation modes
(Pos. 9 “Figure 2.1 - Overview” on page 3).
In the "PASSIVE" mode, the loudspeaker is operated on a
passive crossover with a single amplifier channel.
In "Biamp" mode, the woofer (1×15") and high frequency
path (1×1.4") are operated with separate amplifier chan-
nels. The high pass filter for the high frequency driver and
low pass filter for the low frequency driver remain opera-
tional in the signal path and in circuit even in "Biamp"
mode “Figure 3.2 - Wiring diagram” on page 5.
Figure 2.2
NOTE
Never change the operation mode while the loudspeaker is connected. In addition to set-
ting the switch, the corresponding preset on the amplifier must be changed.

4. Setting up the loudspeaker
The C15 loudspeaker is designed for horizontal operation as a monitor as well as stand-
ing, vertical operation. A variety of accessories is available from TW AUDiO to securely
attach the loudspeaker, e.g. on stands or suspended horizontally or vertically from
trusses and motor lifts.
The horn of the C15 loudspeaker is positioned such that the horizontal coverage is 55°
and the vertical coverage is 70°. In some situations, it may be advantageous to switch
the coverage of the high frequency range. The horn of the C15 loudspeaker can be ro-
tated for this. Proceed as follows.
1. Place the C15 loudspeaker with the wedge inclined toward you with the grill facing
up. Ensure that the working surface is clean with a non-slip finish.
2. To remove the front grill of the loudspeaker, use a 3 mm hex key. Remove the four
screws on the top and bottom of the loudspeaker enclosure (two on each side).
3. Release the four screws of the horn using a 5 mm hex key.
4. Pull the horn upward out of the loudspeaker enclosure.
6. Check that the foam between the grill and horn is properly seated.
7. Screw the front grill back on hand-tight.
4.1 Setup
WARNING
Ensure that the loudspeakers are securely attached to prevent personal injury and
property damage.
NOTE
TW AUDiO recommends using only the accessories specified by TW AUDiO to install
and secure the loudspeakers.
4.2 Rotating the horn
NOTE
5. Rotate the horn by 90°. Ensure that you hold onto it firmly at all times. This will pre-
vent damage to the woofer membrane. Screw the horn back on. For this purpose,
use a 6-Nm torque wrench.
