If the system seems to be malfunctioning or damaged, stop using it at once and have it repaired by a NEXO qualified technician.
Do not expose the system directly to the sun or to the rain, do not immerse it into fluids, do not place objects filled with liquid on the
system. If a liquid gets into the system, please have it inspected by a NEXO qualified technician.
The connection should be performed by qualified technician, by ensuring that power is off.
Operating temperature with temperate climate: 0°C to +40°C (+32°F to +104); -20°C à +60°C (-4°F to +140°F) for storage.
SAFETY INFORMATIONS
Read this manual before using the speaker.
Keep this manual available for further reference.
Observe all warnings and cautions.
Please check the NEXO Web site nexo-sa.com to get the most up-to-date version of this manual.
Ensure you are aware of the safety rules applying to rigging, stacking or installing on tripod or speaker stand. Failure to observe
these rules may expose persons to potential wounds or even death.
Only use the system with accessories specified by NEXO.
Please always consult a NEXO-accredited technician if the installation needs architectural works and observe following precautions:
Mounting Precautions:
- Please select screws and mounting location supporting 4 times the system weight.
- Do not expose the system to excessive dust, vibrations, to extreme cold or hot temperatures, to reduce the risk of damaging
components.
- Do not place the system in an unstable position: it could fall accidentally.
- t does not exceed
Connection and Powering Precautions:
- Unplug connected cables before moving the system.
- Power off the system before connecting the system.
- When switching on the installation, the amplifier must be powered last; when switching the installation off, shut off the
amplifier first.
- If you work by cold temperatures, progressively raise the level to nominal value during the first minutes of use, to allow the
system components to stabilize.
Please check regularly the system condition.
HIGH ACOUSTIC PRESSURE LEVELS
Exposure to very high sound pressure levels may cause permanent hearing losses. Degrees of hearing losses may be different
from one person to another, but almost everybody will be affected if exposed to high sound pressure levels during a long period of
time. The OSHA (Occupational Safety and Health Administration) American Agency specified the following maximal exposures:

→The MSUB12 is a compact high technology arrayable sub, the ideal companion for the GEOM6 line array element, sharing
same aesthetic design and arrayable in the same flown or stacked cluster.
→Versions:
•MSUB12-I: for fix applications; Black
•MSUB12-IPW: for fix applications; White
→Connectors:
•MSUB12-I: 2 cable-glands (clamping range, Ø 10 to 14mm).
•MSUB12-I is supplied with a fixed cable (HO7ZZ-F), 2x2.5mm2section, length 4m, outside diameter 11.5mm
±1.5mm.
•(+): Brown / Red ; (-): Blue / Black
→Amplification:
•The MSUB12 must be used with a NEXO processor to handle EQ, phase alignment, crossover and
excursion/thermal protection for the system loudspeakers.
•The following table shows the number of MSUB12 subwoofers usable with each solution.

SETTING RANGE
MSUB12-I Page 5 / 20
SETTING RANGE
Please consult nexo-sa.com for NEXO TD Controllers firmware information.
There are two setting ranges for surrounding speaker MSUB12:
→« OMNI » setups; For a traditional use of the subwoofer in omnidirectional radiation (require at least one subwoofer and a
channel of amplifier).
- 55 85 Hz
- 55 120 Hz
- 55 150 Hz
- 63 120 Hz
- 63 150 Hz
→« CARDIO » setups; For a directional use (cardioid) of subwoofers (require at least two subwoofers and two channels of
amplifier):
•Setups « FR » (Front)
- 55 85 Hz
- 55 120 Hz
- 55 150 Hz
•Setups « BA » (Back)
- 55 85 Hz
- 55 120 Hz
- 55 150 Hz
•The ideal ratio for a directional use is 2 x MSUB12 in CARDIO FRONT mode on top of 1x Reversed MSUB12 in
CARDIO BACK mode. From 1:1 to 4:1 ratio can be used
OMNI Assembly
CARDIO Assembly
SETTING RANGE
Page 6 / 20 MSUB12-I
With 1 to 3 GEOM6
Box
For these configurations, MSUB12 should use the 55-85 Hz setup (85 Hz crossover should be used for
GEOM6 as well).
For stack configuration using MSUB12 in OMNI or CARDIO mode with 1 Back and 2 Front and GEOM6
on top of them, MSUB12 should use the 55-85 Hz setup (85 Hz crossover should be used for GEOM6 as
well). A small overlap could have impact if needed, for example use MSUB12 with 55-120 Hz setup.
SETTING RANGE
MSUB12-I Page 7 / 20
With 4 to 6 GEOM6
For long throw application, MSUB12 should use the 55-120 Hz setup (120 Hz crossover should be used
for GEOM6 as well). If a larger stacked Sub is used all together, MSUB12 should use the 63-120 Hz
setup.
SETTING RANGE
Page 8 / 20 MSUB12-I
With 7 to 12 GEOM6
For very long throw application, MSUB12 should be deployed using the 550-120 Hz setup (120 Hz
crossover should be used for GEOM6).
