2WARNINGS
PRECAUTIONS
Do not open the speaker, do not try to disassemble it neither to modify it in any way. The system doesn’t include any user-repairable part.
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.
- For fixed installations wind loading has to be taken into account in accordance to the national standards.
- If the system is used on a tripod, please ensure the tripod’s specifications are adapted and that it’s height does not exceed
1.40m/55”. Do not move the tripod with the system in position.
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:

WARNING
All MSUB15 accessories are specifically rated in agreement with structural computations.
Never use other accessories –including push-pins –when assembling MSUB15 cabinets than the ones provided by NEXO: NEXO
will decline responsibility over the entire MSUB15 accessory range if any component is purchased from different supplier.
All MSUB15 accessories have been designed so that cabinet are arrayed vertically.
VNT-BUMPM10
- Rated for a maximum of 12 GEOM10 or 8 MSUB15.
- Maximum quantity for flown vertical cluster is:
NGEOM10 + 1.5*NMSUB15 <= 12
- 2 rigging points 2 points with retractable rings.
- Usable with VNT-EXBARM10 for a one rigging point.
- Ground stack assembly alone, or with VNT-GSTKM10S /
VNT-GSTKM10L.
- 2 locations for laser/inclinometer.

DESCRIPTION Page 7/16
5DESCRIPTION
- The MSUB15-I is a compact high technology arrayable sub, the ideal companion for the GEOM10 line array element, sharing
same aesthetic design and arrayable in the same flown or stacked cluster.
- Versions:
oMSUB15-I: for fix applications; Black
oMSUB15-PW: for fix applications; White
oMSUB15 and MSUB15-PW, for Touring versions (see user manual MSUB15).
- Connectors:
o2 fast connectors in front and back. Seal your connections for an outdoor use
o(+): Brown (or Red) / (-): Blue (or Black)
- Amplification:
oThe MSUB15 must be used with a NEXO processor to handle EQ, phase alignment, crossover and excursion/thermal
protection for the system loudspeakers. There are two NEXO processor series supporting the MSUB15 subwoofer:
NXAMP (4-channel) amplified processors and DTD processors (stereo + sub).
oThe following table shows the number of MSUB15 subwoofers usable with each solution.
NXAMP4x1MK2 (bridged)

6SETTING RANGE
Please consult nexo-sa.com for NEXO TD Controllers firmware information.
There are two setting ranges for speaker MSUB15:
- « OMNI » setups (available on NXAMP and DTD); For a traditional use of the subwoofer in omnidirectional radiation (require at
least one subwoofer and a channel of amplifier).
oOmnidirectional Main setup, with low-pass at 63, 75, 85, 95 or 120 Hz.
oOmnidirectional Monitor setup, with low-pass at 63, 75, 85, 95 or 120 Hz.
- « CARDIO » setups (only available on NXAMP); For a directional use (cardioid) of subwoofers (require at least two subwoofers and
two channels of amplifier):
oCardioid back and front setups, with low-pass at 63, 75, 85, 95 or 120 Hz.
▪Setup « FR » (Front) for the subwoofer pointed at the audience.
▪Setup « BA » (Back) for the subwoofer turned around.
oThe ideal ratio for a directional use is 2 x MSUB15 in CARDIO FRONT mode on top of 1x Reversed MSUB15
in CARDIO BACK mode. From 1:1 to 4:1 ratio can be used.
Page 8/16 SETTING RANGE
« OMNI »Assembly « CARDIO » Assembly
➢With 1 to 3 GEOM10
oFor these configurations, crossover frequency 85Hz is recommended (85 Hz also for pour GEOM10).
SETTING RANGE Page 9/16
oFor stack configuration using MSUB15 in OMNI or CARDIO mode with 1 Back and 2 Front and GEOM10 on top
of them, cross over 85Hz is recommended (85 Hz also for GEOM10). A small overlap could have impact if
needed, for example (MSUB15 120 Hz and GEOM10 75 Hz);
➢With 4 to 6 GEOM10
oFor long throw flying application, crossover 95 Hz is recommended (CARDIO mode).
Page 10/16 SETTING RANGE
oFor long throw stacking application, up to 6 GEOM10, crossover 85 Hz is recommended (also for GEOM10).
➢With 7 to 12 GEOM10
oFor very long throw application, with flowned or stacked MSUB15, recommended MSUB15-I cardioid mode,
cross over MSUB15-I 95 HZ and 12 GEOM10 cross over 75Hz for maximum impact.
SETTING RANGE Page
11/16
oGround Stack Sub design is:
➢GEOM10 MON and MSUB15 MON
oMinimum phase setup not compatible with others.
oUsed for high power stage Monitor, DJ Monitor, Drum Fill, Stack side.
oAlways use same cross over between GEOM10 and MSUB15, no overlap possible without doing phase
adjustment by yourself.
oVery high LF headroom.
oClarity adjustment using -3dB on ArrayEQ –75 Hz crossover default.
