Nexo GEO S805 Tangent Array Module

Nexo GEO S805 compact high output array module is designed for use in vertical tangent arrays.

Nexo GEO S805 Tangent Array Module

The Hyperboloid Reflective Wavesource allows multiple GEO S8 loudspeakers to radiate tangent wavefronts with coherent output.

The 5° wavesource is optimised for the construction of curved vertical arrays that deliver equal power to equal coverage areas for consistent SPL from front to rear of the audience area. Advanced DSP algorithms, applied by the NX242 TDcontroller, precisely integrate GEO S systems with CD12 SubBass cabinets, so they may be flown together, without causing any interference between the GEO S and CD12 wavefronts.

Since 2002, the S805 has consistently demonstrated a remarkable ability to project coherent sound over long distances. Arrays of up to 23x S805 Array Modules and 1x S830 Array Module have been deployed for large indoor and outdoor events, with consistently excellent results in the reproduction of music and speech.

Features

Nexo GEO S805 Tangent Array Module

  • S805 is optimised for vertical tangent arrays
  • High power, long excursion neodymium 8" woofer delivers full range output from compact enclosures
  • Light weight (13kg per module including Array Assembly System) allows GEO tangent arrays to be hung almost anywhere
  • Configurable Directivity Device allows dispersion in the noncoupling plane to be changed from 80° to 120° through bolton flanges that alter the flare of the diffraction slot’s exit
  • Directivity Phase Device combines enhanced line source coupling in vertical arrays with extended low frequency response
  • GEOSoft array design software predicts vertical tangent array performance for a wide range of venues
