Safety and regulations
Important safety instructions
The lightning flash with and 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 the 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

Stasys 218 overview
The Stasys 218 is a double 18”, reflexloaded, low frequency enclosure built
around traditional principles but designed with Stasys philosophy and
attention to detail. Resonance mapping has influenced the optimal brace
positioning and minimal destructive nodal conditions, creating a superior
structure with minimum mass, the least possible cabinet colouration, and
vastly increased output. Marrying a technologically advanced enclosure with a
powerful transducer, results in a phenomenal package with state-of-the-art
performance.
Key features
- High power reflex loaded double 18” low frequency enclosure
- 2400 Watts AES power handling
- Optimally damped, minimal mass cabinet
- Dual 18” low frequency transducers with 4” coils

Cabling 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 | 4 W load | 2 W load |
|---|---|---|---|
| 2.50 mm2 | 13 AWG | 18 m | 9 m |
| 4.00 mm2 | 11 AWG | 30 m | 15 m |

Amplifier loading guidelines 
Ensure all amplifier channels are loaded equally. Limiters engage correctly. Cabinets acoustic principles are the same.
Operating modes
Manual handling guidelines
To avoid manual handling hazards please note the following:
- Be sure to secure any loudspeaker systems following correct local procedures/guideline
- Low frequency enclosures are heavy and require a minimum of two people to move; for more information on safe handling consult INDG143.
Typical modes
Although the modes of arrangement shown here are typical operating modes for
low frequency enclosures, the Stasys 218 system’s symmetrical design lends
itself to wide range
of configurations. Simple planer arrays and stacks to directional and
steerable arrays are possible given suitable electronics and presets. Contact
your local Void distributor/dealer for more information.
Cardioid modes
As low frequency enclosures are omnidirectional, rear projection can cause a
range of difficulties. If there is a wall behind the array, the sound wave can
reflect off the surface and may cause cancellation in front if it arrives out
of phase with the wave from the source.
Another problem may occur during performances where an array is deployed in
front of the stage, possibly creating a maximum sound pressure level that
makes it difficult for some performers. Adopting a cardioid configuration can
overcome this problem as it creates a heart shaped horizontal dissipation
reducing the rear projection. A variety of cardioid configurations are
available, as shown below. For other layouts or more information, please
contact your local Void distributor/dealer.
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 Stasys 218 loudspeakers should only be serviced by a fully-trained
technician.
No user serviceable parts inside. Refer servicing to your dealer.
Return authorisation
Before returning your faulty product for repair, please remember to get an
R.A.N. (Return Authorisation Number) from the Void dealer who supplied the
system to you. Your dealer will handle the necessary paperwork and repair.
Failure to go through this return authorisation procedure could delay the
repair of your product.
Note that your dealer will need to see a copy of your sales receipt as proof
of purchase so please have this to hand when applying for return
authorisation.
Shipping and packing considerations
- When sending a Void Stasys 218 loudspeaker to an authorised service centre, please write a detailed description of the fault and list any other equipment used in conjunction with the faulty product.
- Accessories will not be required. Do not send the instruction manual, cables or any other hardware unless your dealer asks you to.
- Pack your unit in the original factory packaging if possible. Include a note of the fault description with the product. Do not send it separately.
- Ensure safe transportation of your unit to the authorised service centre.
