Nexus 6 overview
Ideal for larger venues, the four-way Nexus 6 has an innovative internal
transducer layout and 20 high power drivers, housed in a sculpted fibreglass
enclosure. Virtual Arc technology forms a common acoustic centre at the back
of the array, overcoming all the disadvantages of a traditional array where
multiple sound sources emit from different locations. Instead, dispersion,
phase, coherency and timing are all controlled and unified, ensuring the same
sound is experienced by the audience, regardless of where they are standing.
Whether placed on low frequency enclosures to form a dance stack or flown
independently, the Nexus 6 provides intelligent performance and styling.
Key features
- Two-way bi-amped sculpted loudspeaker array
- Virtual Arc technology
- Unified dispersion, phase and timing
- 20 discrete proprietary drivers
- Stack mounted or proprietary flying system
- Fibreglass composite construction
- Smooth cellulose finish

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.

Installation safety
To avoid mechanical hazards, please note the following:
- Safety regulations vary in different regions. Full compliance with those regulations must be your priority
- Installations must only be undertaken by fully qualified and experienced engineers/technicians who understand local regulations
- This may include consulting a structural engineer before installation of wall brackets
- Remember that all personnel have a duty of care to themselves, to their assistants, to the venue staff and to the public
- Before lifting any part of the system above head height, check the whole rig for loose tools or other items that may fall and cause injury
- Do not use a telephone (even if hands-free) whilst installing. Always concentrate fully on the installation operation
- Do not install equipment that is worn, damaged, corroded, mishandled or over-stressed in any way
- Use only Void-approved mounting equipment and accessories
- Secondary safeties should be provided in all instances where cabinets are flying or fixing overhead and should conform to local regulations
Ground Stacking
-
Step 1: Removing the backing plate from the Nexus 6 bracket by removing the M8 and M12 bolts from the bracket assembly.
-
Step 2: Remove all eight M8 bolts from the rear of the Nexus 6 loudspeaker.
-
Step 3: Attached the backing plate to the Nexus 6 ensuring that all eight M8 bolts are securely fastened.
-
Step 4: Carefully lower the Nexus 6 loudspeaker into position onto the bracket assembly.
Note: Nexus 6 loudspeakers are heavy and require a minimum of two people to lift. At this stage of the mounting procedure, it becomes necessary to have three people, two to lift the Nexus 6 loudspeaker and one to attach the bracket. -
Step 5: With the lifting equipment still in place attach the M12 bolt to the bracket assembly.
-
Step 6: Adjust the vertical angle required using the datum line to select the required angle (shown here set to zero degrees indicated in yellow). The Nexus 6 bracket is capable of negative angle adjustment to point down (indicated in black) and positive angle to point up (indicated in red). The corresponding hole for each angle is indicated by that number and its colour.
-
Step 7: Once the vertical angle has been selected attach the M8 bolt through the appropriate slot.
-
Step 8: Loosen, but do not remove, the M8 bolt from the rear of the bracket assembly.
-
Step 9: Adjust the horizontal angle of the Nexus 6 to the desired direction using the angle finder on the top of the bracket assembly.
-
Step 10: Secure the M8 bolt on the rear of the bracket assembly but ensure not to over-tighten the bolt as it may cause damage to the nut and bracket assembly.
Service
Void Nexus 6 loudspeakers should only be serviced by a fully-trained technician.
- No user-serviceable parts inside. Refer to servicing to your dealer.

Appendix
Architectural Specifications
The loudspeaker shall be an active two-way bi-amped system consisting of
twelve high power 6.5” (165.1 mm) direct radiating low frequency (LF)
transducers, and eight 1” (25.4 mm) high frequency (HF) compression drivers,
each mounted on a dedicated waveguide. With twenty discrete proprietary drive
units, Virtual Arc technology is implemented on every component to form a
common virtual point source rearwards of the array resulting in a better and
more controlled directivity, coherence, phase and time alignment between all
components. The LF transducers shall be constructed on a cast aluminum frame,
with a treated paper cone, 44 mm (1.7”) voice coil, wound with copper wires on
a high-quality voice coil former, and neodymium magnets, for high power
handling and long-term-reliability. The HF transducers shall project their
sound through a high precision constant directivity wave-guide, with a 76.2 mm
(3”) baffle diameter, to achieve directivity pattern control between the
different drivers with no cancellations and low distortion. Performance
specifications for a typical production unit shall be as follows: the usable
on-axis bandwidth shall be 78 Hz to 21 kHz (±3 dB) and shall average 50°
directivity pattern on the vertical axis and 110° on the horizontal one (-6 dB
down from on-axis level) from 1 kHz to 12 kHz; maximum SPL of 141 dB peak
measured at 1 m using IEC268-5 pink noise. Power handling shall be 2700 W AES
for the LF section at a rated impedance of 2 x 5.3 Ω and 640 W AES for the HF
section at a rated impedance 2 x 4 Ω. The system shall be powered by its own
dedicated power amplification modules with DSP management, from which
crossover points will also be set, with the wiring connection via one Neutrik
speakON™ NL8. The enclosure shall be of a special fibreglass composite with a
smooth cellulose finish of any RAL colour. The system shall be stack mounted
with a dedicated stand or can also be suspended with a load-tested suspension
system. The external dimensions of the enclosure shall be (W) 561 mm x (H)
1266 mm x (D) 430 mm (22.1” x 49.8” x 16.9”). Weight shall be 73.4 kg (161.8
lbs) including stand. The loudspeaker shall be the Void Acoustics Nexus 6.
