Overview
The compact, 2-way GEO S1210 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 very narrow-Q (10°) device in single-source mode, S1210’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.
Features
- Coherent Wave Propagation from NEXO’s Advanced GEO Hyperbolic Wavesource
 - Advanced Constant Velocity Profile Output from 5.1° Wavefront Curvature
 - Integral Rigging System with Angles from 0.20° to 10°
 - NS-1 Configurable, EtherSoundTM (Network)
