Nexo GEO S830 Tangent Array Module

Compact Nexo GEO S830 high output array module is intended for horizontal tangent arrays or as a downfill element in curved (tangent) vertical arrays to establish consistent SPL in all coverage areas.

Nexo GEO S830 Tangent Array Module

The unique geometry of the HRW™ allows the S830 to be used as a down-fill for vertical tangent arrays of S805 modules, or as a 30° building block in horizontal tangent arrays. In either orientation, the S830 delivers totally coherent high frequencies, transparent midrange and solid low end with its neodymium 1"- exit compression driver and long excursion 8" cone transducer.

The GEO S830 has proven the value and effectiveness of both vertical and horizontal tangent arrays. Its patent-pending Hyperboloid Reflective Wavesource creates tangent wavefronts whether the adjacent cabinets are additional S830s or 0.125°-5° GEO S805s.


Nexo GEO S830 Tangent Array Details

  • S830 can be deployed in horizontal or vertical tangent arrays
  • High power, long excursion neodymium 8" woofer delivers full range output from compact enclosures.
  • Light weight (13kg per module including precision array assembly system) construction allows GEO tangent arrays to be hung almost anywhere.
  • Configurable Directivity Device allows dispersion in the noncoupling plane to change from 80° to 120° through bolt-on 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.
