GEO S1230
The compact, 2-way GEO S1230 is a scalable loudspeaker module that displays exceptional MF-LF output (103dB SPL nominal sensitivity -1W @1m) from a single12” loudspeaker and NEXO’s proprietary Directivity Phase Device (DPD). A narrow-Q (30°) device in single-source mode, S1230’s unique Hyperboloid Reflective Wavesource (HRW) allows coupled S1210/1230s to radiate as coherent, wavefronts, yeilding precise pattern control in vertical or horizontal arrays. S12 arrays display traditional “tight-pack” pattern control in the non-coupled plane.
Key Features
- Coherent Wave Propagation from NEXO’s Advanced GEO Hyperbolic Wavesource
- Advanced Constant Velocity Profile Output from 28.5° Wavefront Curvature
- Integral Rigging System with Angles from 22.5° to 30°
- NS-1 Configurable, EtherSoundTM (Network)
