Yamaha GEOS1230ST-PW 12'' 2 Way Stadium Tangent Array Module (White)

High Performance Loudspeaker for Stadium Installations

The Yamaha GEOS1230ST-PW is a compact, custom-painted stadium tangent array module engineered for demanding large-scale sound reinforcement. Designed specifically for stadium and long-throw applications, this 12-inch 2-way loudspeaker delivers exceptional clarity and coverage over extended distances. Its narrow 30° trapezoid shape and precision-engineered waveguide ensure highly controlled dispersion, making it ideal for environments where consistent sound coverage is critical.

Advanced Acoustic Design for Long-Throw Applications

This model’s unique Hyperboloid Reflective Wavesource (HRW) technology produces a coherent wavefront, allowing multiple modules to be coupled for uniform sound propagation. Whether deployed in horizontal or vertical arrays, the GEOS1230ST-PW maintains a smooth frequency response and consistent coverage, even in challenging acoustic spaces. Its coupled MF/HF pattern control is array-dependent and configured using NS-1 array design software for precise venue-specific tuning.

Powerful Output with Excellent Speech Intelligibility

With a nominal sensitivity of 105 dB SPL (1W @ 1m), the GEOS1230ST-PW delivers impressive mid-low frequency output and crystal-clear speech reproduction. The integration of NEXO’s proprietary Directivity Phase Device (DPD) ensures accurate phase alignment and reduced interference, resulting in more intelligible audio for announcements, commentary, and music playback in stadium settings.

Custom Painted Finish for Seamless Integration

The GEOS1230ST-PW is finished in a painted white custom coat, allowing it to blend visually into architectural designs without compromising performance. This makes it an excellent choice for venues where aesthetics are as important as sound quality, such as sports arenas, concert halls, and large public venues.

Versatile Array Configuration Options

This module’s coverage can be configured for non-coupled MF/HF operation at 80° or 120°, giving sound system designers the flexibility to adapt the array to the venue’s unique acoustic and structural requirements. The GEOS1230ST-PW’s versatility in both pattern control and physical configuration makes it a valuable component in professional sound installations.

Designed for Reliability in Demanding Environments

Built for long-term use in professional installations, the GEOS1230ST-PW is constructed from high-quality materials to withstand the rigors of outdoor and high-use venues. From sports stadiums to large-scale performance spaces, this loudspeaker is engineered to deliver reliable, high-output sound in the most demanding conditions.
