WARNINGS
PRECAUTIONS
Do not open the speaker, do not try to disassemble it either to modify it in
any way. The system doesn’t include any user-repairable parts.
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 a qualified technician, by
ensuring that the 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 INFORMATION
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.
– If the system is used on a tripod, please ensure the tripod’s specifications
are adapted and that its 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 SOUND PRESSURE LEVELS
Exposure to very high sound pressure levels may cause permanent hearing loss.
Degrees of hearing loss may be different from one person to another, but
almost everybody will be affected if exposed to high sound pressure levels for
a long period of time. The OSHA (Occupational Safety and Health
Administration) American Agency specified the following maximal exposures:
| Number of Hours | Sound Pressure Level (dBA), Slow Response |
|---|---|
| 8 | 90 |
| 6 | 92 |
| 4 | 95 |
| 3 | 97 |
| 2 | 100 |
| 1 ½ | 102 |
| 1 | 105 |
| ½ | 110 |
| ¼ or less | 115 |

EQUIPMENT
3 locations for hanging, 1 on the back and on both sides.
WARNING: The depth of the M10 thread is 14mm (0.55 inch). 
Assembly on distance rod or speaker stand
Place distance rod on the connector plate (M20) of the Sub.
Place PLADAPT on P15-I. Put the assembly on the distance rod/monitor stand
(diameter of 35mm),|
---|---
IMPORTANT
The Speaker stand must be rated for P15 weight.
The Speaker stand must always be installed on a horizontal surface.
Stand height and footprint must be defined to prevent the assembly from
collapsing.
Ensure that audience is not allowed within a safety area whose
radius is equal or higher than assembly height.
Test the steadiness of the assembly by pushing in all directions.
DESCRIPTION
→ The P15 is a compact full-range coaxial speaker
→ P15 HF Dispersion:
- 60° – 60° with standard horn
- 90° – 40° with PNU-P15FLG9040
- PS with PNU-P15FLGPS (Asymmetrical Dispersion)
→ P15 can be used alone or with L18 subwoofer
→ The speaker is equipped with a cable gland (clamping range, ø 5 to 12 mm), supplied with a fixed cable (HO7ZZ-F), 2 x
1.5mm
2 section, length 4m, outside diameter 8mm ±1mm.
→ (+) Red/Brown / (-) Black/Blue
→ Amplification
- The P15 speakers must be used with a NEXO processor to handle EQ, phase alignment, crossover and excursion/thermal protection for the system loudspeaker. There are two NEXO processor series supporting the P 15 speakers: NXAMP (4 channels) amplified processors and DTD processors (stereo + sub). DTD processors ensure optimal performances when used with DTDAMP power amplifiers.
- The following table shows the number of P15 speakers and L18 subwoofers usable with each solution.
| NXAMP4X1mk2 (BRIDGED)| NXAMP4X2mk2| NXAMP4X4mk2
---|---|---|---
P15| Up to 2 per channel| Up to 2 per channel| Up to 4 per channel
L18| 1 per channel| 1 per channel| Up to 2 per channel
PRESET
Please consult nexo-sa.com for NEXO TD Controllers firmware information.
For the P15, the following setups are available:
→ MAIN is the recommended setup for most FOH applications, similar to the
previous firmware setup.
→ MONITOR is recommended for monitoring applications. Warning: this setup is a
low latency setup and therefore its phase is not compatible with other NEXO
cabinets, including subs.
Preset
- P15 MON PA 6060, with high-pass at 57 or 85 Hz.
- P15 MON PA 9040, with high-pass at 57 or 85 Hz.
- P15 MON PA PSguide, with high-pass at 57 or 85 Hz
- P15 MAIN PA 6060, with high-pass at 57, 85 or 120 Hz.

Stage monitor applications with Subs (OMNI or CARDIO
modes)
Front-of-house applications with Subs (OMNI or CARDIO modes)
HF DIRECTIVITY
→ The P15 speaker can be used in horizontal or vertical positions.
→ The standard horn is a 60° – 60° dispersion. It’s easy to change the
dispersion by adding a specific flange. Different mounting possibilities and
flange rotation allow to deal with every request.
When replacing the grille, ensure it is well positioned in the top blade before fasten the hooks with the screws.
CROSSOVER FREQUENCY
→ 57 Hz: Full range application.
→ 85 Hz: Use as « front fill » on stage, complementing the main system. Use
with a NEXO subwoofer, e.g. L18.
→ 120 Hz: For long throw applications.
