Safety and Regulations
Important safety instructions
- The lightning flash with an arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
- The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
Safety instructions – read this first
-
Read these instructions.
-
Keep these instructions.
-
Heed all warnings.
-
Follow all instructions.
-
Do not use this apparatus near water.
-
Clean only with a dry cloth.
-
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
-
Do not install near any heat source such as radiators, heat registers, stoves, or other such apparatus that produce heat.
-
Do not defeat the safety purpose of the grounding-type plug. A grounding type plug has two blades and a third grounding prong. The third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
-
Protect power cords from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit the apparatus.
-
Only use attachments and accessories specified by Void Acoustics.
-
Only use with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
-
Unplug the apparatus during lightning storms or when unused for long periods of time.
-
Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any way, such as when the power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. -
Since the mains power supply cord attachment plug is used to disconnect the device, the plug should always be easily accessible.
-
Void loudspeakers can produce sound levels capable of causing permanent hearing damage from prolonged exposure. The higher the sound level, the less exposure needed to cause such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker.

This guide is provided to help familiarise the user with the loudspeaker
system and its accessories. It is not intended to provide comprehensive
electrical, fire, mechanical and noise training and is not a substitute for
industry-approved training. Nor does this guide absolve the user of their
obligation to comply with all relevant safety legislation and codes of
practice. While every care has been taken in creating this guide, safety is
user-dependent and Void Acoustics Research Ltd cannot guarantee complete
safety whenever the system is rigged and operated.

Nexus XL overview
Applying the five resonant chamber theory used in the ever-popular Stasys X,
further refining this design principle has led to previously unimagined levels
of performance. The Nexus XL has it all, with its impressive transient
response and articulation, plus exceptionally high levels of efficiency, power
handling and extended low frequency response. Well suited to modern styles of
music, it still retains the efficiency and extended low frequency response
that only
a very large transducer can provide. For lower power handling, the Nexus XL
serves as an alternative to the Nexus X and is to be used with the Nexus Q
upper bass enclosure.
Key features
- Single high power 21” transducer
- Five resonant chambers
- Very high efficiency
- Fast transient response

Cable and Wiring
Electrical safety
To avoid electrical hazards please note the following: Do not access the
inside of any electrical equipment. Refer servicing to Void-approved service
agents.
Cable considerations for fixed installations
We recommend specifying installation-grade Low Smoke Zero Halogen (LSZH)
cables for permanent installations. The cables should use Oxygen Free Copper
(OFC) of grade C11000 or above. Cables for permanent installations should be
compliant with the following standards:
- IEC 60332.1 Fire retardancy of a single cable
- IEC 60332.3C Fire retardancy of bunched cables
- IEC 60754.1 Amount of Halogen Gas Emissions
- IEC 60754.2 Degree of acidity of released gases
- IEC 61034.2 Measurement of smoke density.
We suggest using the following maximum copper cable lengths to keep level losses below 0.6 dB.
| Metric mm2 | Imperial AWG | 8 Ù load | 4 Ù load | 2 Ù load |
|---|---|---|---|---|
| 2.50 mm2 | 13 AWG | 36 m | 18 m | 9 m |
| 4.00 mm2 | 11 AWG | 60 m | 30 m | 15 m |

Amplifier loading guidelines
Ensure all amplifier channels are loaded equally. Limiters engage correctly. Cabinets acoustic principles are the same.
Adjustments
To avoid damage when making adjustments please note the following:
- Removing the grille can cause debris to collect within the enclosure, take care to remove anything that may have collected internally
- Do not use impact tools.
Wheel removal
- Step 1: Remove all four M6 bolts with a 13 mm spanner/wrench.
- Step 2: Remove/add the wheels and keep in a safe place. Repeat the process for the other three wheels.
- Step 3: Replace the M8 bolts by hand until finger tight before using hand tools.
Note: Replacing bolts is of particular importance as without them there can be air leakage and detuning.
Grille removal
- Step 1: Undo all twelve M6 tab bolts using a 4 mm Allen key, take care NOT to remove the tab bolts as they may become lost within the enclosure.
- Step 2: Remove grille.
- Step 3: Replace the M6 bolts by hand until finger tight before using hand tools.
Service
Void Nexus XL loudspeakers should only be serviced by a fully-trained technician.
No user-serviceable parts inside. Refer servicing to your dealer.

single high power 21” (533.4 mm), long excursion, low frequency (LF)
transducers mounted in a rectangular enclosure. The low frequency transducers
shall be constructed on a cast aluminium frame, with a treated paper cone,
dual 152.4 (6”) voice coil, wound with copper wires on a high-quality voice
coil former and a neodymium magnet for high power handling and long-term
reliability. Performance specifications for a typical production unit shall be
as follows: the usable bandwidth shall be 30 Hz to 150 Hz (±3 dB) and have a
maximum SPL of 141 dB peak (135 dB continuous) measured at 1 m using IEC268-5
pink noise. Power handling shall be 2000 W AES at a rated impedance of 8 Ω and
a pressure sensitivity of 104 dB measured at 1W/1m. The system shall be
powered by its own dedicated power amplification module with DSP management.
The wiring connection shall be via two Neutrik speakON™ NL4 (one for input and
one for loop-out to another speaker), to allow for pre-wiring of the connector
before installation. The enclosure shall be constructed from a 18 mm multi-
laminate birch plywood finished in a textured polyurea and shall contain
fixture points for pressed steel, powder-coated grille to protect the horn
path from object ingress. The cabinet shall have eight handles (four per side)
for efficient manual handling. External dimensions of (H) 754 mm x (W) 738 mm
x (D) 860 mm (29.7” x 29” x 3.9”). Weight shall be 90 kg (198.4 lbs). The
