GEOS1230-EN54
Version of the standard GEOS1230 certified as complying with the EN 54 standards for voice alarm systems. 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.
