3.2 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.

3.3 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
