Yamaha GEOS1230ST-CP 12'' 2-Way Stadium Tangent Array Module

Professional Stadium Loudspeaker for Long-Throw Applications

The Yamaha GEOS1230ST-CP is a compact, custom-painted 12-inch 2-way stadium tangent array module designed for high-output, long-distance sound reinforcement. Built for large venues and challenging acoustic spaces, it delivers powerful, controlled audio with precision coverage. Its 30-degree trapezoid shape and advanced waveguide engineering make it an ideal choice for stadium installations that demand consistent performance across large areas.

Advanced Waveguide Technology for Coherent Coverage

Equipped with NEXO’s Hyperboloid Reflective Wavesource (HRW) technology, the GEOS1230ST-CP produces coherent wavefronts that maintain sound integrity over long distances. When multiple units are coupled, they provide uniform horizontal or vertical array coverage, ensuring that every seat in the venue experiences the same high-quality sound.

Configurable Directivity for Optimal Performance

The GEOS1230ST-CP offers adaptable MF/HF pattern control, which can be configured through NS-1 array design software to match the exact geometry and requirements of each installation. This flexibility allows sound engineers to choose between non-coupled coverage patterns of 80° or 120°, optimizing clarity and projection for both music and speech applications.

High Output with Superior Speech Intelligibility

With a nominal sensitivity of 105 dB SPL (1W @ 1m), this loudspeaker delivers outstanding MF-LF output from its 12-inch driver. The inclusion of NEXO’s proprietary Directivity Phase Device (DPD) ensures precise phase alignment, resulting in exceptional speech intelligibility and clear music reproduction, even in large, noisy environments.

Custom Painted Finish for Seamless Venue Integration

The GEOS1230ST-CP comes in a custom-painted finish, allowing it to blend into stadium or venue architecture while maintaining a professional, polished appearance. This makes it a practical and aesthetically pleasing choice for installations where visual impact is as important as acoustic performance.

Built for Demanding Environments

Designed for reliability, the GEOS1230ST-CP is constructed from high-quality components to handle the rigors of continuous use in large-scale, high-traffic venues. Whether installed in sports arenas, concert stadiums, or large outdoor event spaces, it delivers dependable, high-output sound performance year after year.
