Safety and Regulations
1.1 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.
1.2 Limitations
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
userdependent and Void Acoustics Research Ltd cannot guarantee complete safety
whenever the system is rigged and operated.

3.2 Air 15 overview
The Air 15 is a reflex-loaded 15” fibreglass subwoofer with styling that
compliments mid-high enclosures from both the Air and Cyclone series. Its
large-scale output allows fully formed systems to be achieved in any
environment.
Air 15’s non-resonant fibreglass enclosure contributes to its impressive SPL
and low frequency extension capabilities. Key features include an IP-53 rating
made possible by ‘ingress proof vent technology’ and UV-resilient paint,
allowing Air 15 to perform in both internal and external spaces requiring
comprehensive coverage. Perfect for medium sized nightclubs and dance venues,
larger bars, restaurants and beach clubs, retail settings and theme parks.
3.3 Key features
- Reflex-loaded 15” low frequency loudspeaker
- Tough high excursion transducer with 4” voice coil

Cable and Wiring
4.1 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.
4.2 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 | 4 Ω load | 2 Ω load |
|---|---|---|---|
| 2.50 mm2 | 13 AWG | 18 m | 9 m |
| 4.00 mm2 | 11 AWG | 30 m | 15 m |
4.3 Phoenix connector
Figure 4.1 shows the rear panel of a Air 15 loudspeaker with the polarity of
the Phoenix connector labelled. When viewed from the rear the connectors are
negative, positive, negative, positive, from left to right.
4.4 Glanded connector wiring
Remove all both M6 bolts from the rear of the connector plate.
Undo the glanded connectors from the rear of the connector plate and remove the rubber plugs from the connectors.
Insert the cable through the glanded connectors and insert the cable into the
connector block as shown.
(Note: The configuration with two cables is for use with link out, if
attaching only one Air 15 then re-insert one of the rubber plugs into the
unused glanded connector.)
Attach the cable to the phoenix connector then position the connector plate and attach it using the M6 bolts.
