Operating Manual M15
Introduction
Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.
The M15 multifunctional speaker is a real all-rounder.
You can use it as a full-range stand-alone box at a party. Or as a delay line speaker. Or
for voice reinforcement. Or as a monitor on stage. Or in combination with one of our passive loudspeakers with B15 as a drum fill or small club PA. Or actively driven with the
B18, B30 or even BSX. And much more.
And in addition, the M15 is equipped with air cargo rigging tracks over which double stud
fittings or flying brackets can easily be mounted without the help of tools.
Mount it. Click it in. Done.

Operating Manual M15
1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loudspeakers.
The M15 loudspeaker was developed for professional use in sound systems. The loudspeaker may only be used by trained and qualified personnel.
Note the operating 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 permitted 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 lb], use suitable aids (dollies, hoisting
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 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.
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 impairment.
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 M15
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 personal injury and property damage.
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.

4. Setting up the loudspeaker
The M15 loudspeaker is designed for standing, vertical and horizontal 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 M15 loudspeaker is mounted at the factory in such a way that the horizontal coverage is 75° and the vertical coverage is 50°. In some situations, it may be advantageous to switch the coverage of the high frequency range. For this purpose, the
horn can be rotated. Proceed as follows.
1. Place the M15 loudspeaker with the wedge inclined toward you with the front 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
fixing screws at the top and bottom of the loudspeaker enclosure.
3. Release the four screws of the horn using a 3 mm hex key. Pull the horn and the
compression driver upward out of the loudspeaker enclosure.
4. Check that the seal between the enclosure and horn is properly seated.
5. Rotate the horn carefully by 90° and reinsert the horn and driver back into the recess. Screw it onto the enclosure using medium-strength thread locker.
6. Screw the front grill back on.
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 secure
the loudspeakers.
4.2 Rotating the horn
Page 11

Operating Manual M15
To create a cable connection 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 M15 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.
4.3 Connecting cables
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 assignment (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 M15 loudspeaker can be found in section 3.2 “Wiring diagram” on page 5.
The two connection sockets on the back of M15 can be used to link multiple loudspeakers on a single amplifier. Note that parallel connection reduces the total impedance (Ω)
seen by the amplifier.
The total impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the amplifier.
4.4 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.

Operating Manual M15
5. Transport and storage
Because the M15 loudspeaker weighs over 20 kg [44,09 lb], two people are needed to
move and transport the unit.
NOTE
To enable a single person to transport two M15 loudspeakers, TW AUDiO recommends
using the CaseM15.
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
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:
• CoverM15 (protective cover for one M15)
• CaseM15 (flightcase for two M15)
The original packaging is unsuitable as permanent storage and transport packaging.
