The NEXO GEO S1230 is a compact, 2-way scalable loudspeaker module with a wider 30° tangential dispersion, making it the downfill partner to the narrow S1210 in GEO S12 arrays. It delivers exceptional MF-LF output from a single 12″ driver and couples with S1210/S1230 modules to radiate as coherent wavefronts with precise vertical or horizontal pattern control.

Downfill CoverageThe wider 30° dispersion makes the S1230 the natural downfill module in a GEO S12 array, filling the near field beneath the tighter S1210 modules. S12 arrays display traditional “tight-pack” pattern control in the non-coupled plane. Coupled pattern control is designed in GEOSoft2 array software.
Features
