Nexo GEO SUB Directional Sub-bass

When flown, up to 16x deep, GEO SUB arrays provide a sub and subwoofer system for GEO D, GEO S or GEO T, effectively crossing over as high as 300Hz.

Nexo GEO SUB Directional Sub-bass

With peak SPL of 139-142dB, GEO SUB's front-loaded 18" transducer integrates exceptional high power handling with an extended frequency range.

When stage stacked, the flexible GEO SUB deploys with GEO D10 as a cardioid subwoofer system, allowing end-users infinite scalability and system placement options, with subbass response down to 35Hz.

Rooted in NEXO's ongoing commitment to precise LF control, the unique GEO SUB design employs two side-firing 12" speakers to create unrivalled, cardioid midbass and subbass coverage.


  • Advanced, controlled cardioid SubBass
  • Arrays with GEO D or flies independently as part of GEO S and GEO T Systems
  • Stage stackable, using proprietary, multi-purpose Bumper Technology
  • Bottom-line engineering for theatre to arena-sized fixed & mobile applications
  • GeoSoft2 configurable and EtherSound™ (network) controllable
  • Exceptional LF and SubBass (33Hz– 250Hz) output from single, 18" with directivity controlled by twin 12" side mounted loudspeakers
  • Advanced Hyper-cardioid LF control from unique, twin, 12" active, side-mounted resistors
  • Less than 80Kg (per box) with ergonomic, elegant, flying and stage-stackable rigging system
