NEXO GEO S1230-ST 12-Inch 2-Way 30-Degree Stadium Tangent Array Loudspeaker

Introducing NEXO's GEO S1230-ST: The Ideal Speaker Solution for Stadiums
When it comes to stadium installations, NEXO's compact, 2-way GEO S1230-ST is the answer. This high-output and long throw version of the standard GEO S1230 cabinet is designed to meet your needs. While a narrow-Q (30°) device in single-source mode, S1230-ST's unique Hyperboloid Reflective Wavesource (HRW) allows coupled S1230-STs to radiate as coherent, wavefronts in either horizontally or vertically arrayed systems. The MF/HF pattern control of GEO S1230-ST is array-dependent, as designed by NS-1 array software, and configured according to venue-specific geometry. If not coupled, the MF/HF coverage configures at 80° or 120°. The S1230-ST module boasts an exceptional MF-LF output (105dB SPL nominal sensitivity -1W @1m) from a single 12" loudspeaker and is equipped with NEXO's proprietary Directivity Phase Device (DPD).
