Yamaha STM-M2890 Nexo STM 90 Degree Omni Module

Versatile Loudspeaker for Downfill and Line Array Applications
The Yamaha STM-M2890 is a high-performance loudspeaker module designed for a variety of professional sound reinforcement applications. With a 90-degree horizontal dispersion, this omni-purpose module is ideal for use as a downfill speaker in large line array configurations or as a standalone compact array system. Whether integrated with the M46 main module or the B112 bass module, the M28 delivers outstanding clarity, power, and versatility.

Durable Injection-Molded Cabinet for Lightweight Strength
Built with an advanced injection-molded cabinet, the M28 is engineered for durability while maintaining a lightweight structure for easier transport and installation. The cabinet's design ensures robust performance in demanding live environments, making it suitable for concerts, festivals, and touring applications. With a format matching the M46 in width but at 2/3 the height, the M28 seamlessly integrates into larger STM systems or functions independently as a compact PA solution.

CompassRig™ and REDLock™ Rigging for Simple, Secure Setup
The M28 features Yamaha’s innovative CompassRig™ and REDLock™ rigging systems, allowing for quick and secure installation. CompassRig™ provides pre-set inter-cabinet angles, making it easy to achieve the desired sound dispersion, while REDLock™ enables operators to lock the front rigging points from the rear of the cabinet, ensuring safe, one-person setup. These intuitive rigging solutions simplify deployment and adjustment for any size array.

High-Output Dual LF and HF Drivers for Exceptional Sound
Equipped with two 8-inch low-frequency drivers and dual high-frequency compression drivers, the STM-M2890 delivers full-range audio with precision and power. With a frequency response of 65Hz–19kHz, this module ensures deep bass, clear mids, and crisp highs, making it suitable for speech, music, and live performances. A peak SPL of 141dB guarantees high output levels for large-scale venues without sacrificing clarity.

Optimized for Modular Flexibility and Scalability
The M28 is designed to function in multiple roles, from a dedicated downfill module in larger setups to a primary loudspeaker in smaller venues. The adjustable splaying angle from 0° to 15° between modules enables fine-tuned dispersion control, ensuring consistent audio coverage across a wide audience area. Its modular design makes it easy to scale up or down, adapting to different performance needs.
