GEO S1230-ST

NEXO’s compact, 2-way GEO S1230-ST is a high-output, long throw version of the standard GEO S1230 cabinet, designed for stadium installations. While a narrow-Q (30°) device in single-source mode, S1230-ST’s unique Hyperboloid Reflective Wavesource (HRW) also allows coupled S1230-STs to radiate as coherent, wavefronts, in either horizontally or vertically arrayed systems. GEO S1230-ST’s coupled MF/HF pattern control is array-dependent, as designed by NS-1 array software, and configured according to venue -specific geometry. Non- coupled MF/HF coverage configures at 80°or 120°.The S1230-ST module displays exceptional MF-LF output (105dB SPL nominal sensitivity -1W @1m) from a single 12″ loudspeaker and NEXO’s proprietary Directivity Phase Device (DPD).
