Yamaha STM-M46 Nexo STM M46 Main Module

High-Power Speaker Module for Large-Scale Sound Systems
The Yamaha STM-M46 is a high-performance loudspeaker module engineered for professional touring and large-scale live sound applications. Designed as the main component of Nexo’s STM system, the M46 delivers exceptional clarity, power, and flexibility. Its injection-molded cabinet and innovative driver technology ensure even coverage across its 90° horizontal dispersion, making it ideal for large venues, stadiums, and concert halls.

Flat-Membrane Drivers for Uniform Sound Distribution
Unlike traditional speaker designs, the M46 utilizes advanced flat-membrane drivers that provide an exceptionally smooth and even frequency response across its entire dispersion area. This design prevents phase interference and ensures a coherent, full-range audio experience with crystal-clear mids and highs. The HF drivers use Ketone Polymer diaphragms, known for their ability to maintain tonal consistency while offering impressive throw distances.

Innovative CompassRig™ and REDLock™ Rigging for Safe, Quick Setup
The M46 is equipped with Yamaha’s CompassRig™ and REDLock™ rigging systems, making deployment easier and safer than ever. CompassRig™ allows for precise pre-setting of inter-cabinet angles, ensuring optimal sound dispersion. Meanwhile, the REDLock™ handle locks the front rigging points from the rear of the cabinet, allowing a single technician to assemble the system securely from one position. This feature speeds up setup time and enhances system stability.

Powerful SPL Performance for High-Energy Environments
With a peak SPL of 145dB, the M46 is capable of delivering massive sound output without distortion. Whether used as part of a full STM array or in standalone configurations, this module provides the high-definition performance required for demanding live events. The frequency response of 85Hz to 20kHz ensures a balanced output that captures every detail of your mix, from deep lows to sparkling highs.

Modular System Integration for Scalable Configurations
The M46 is designed to work seamlessly with other STM components, including the M28 Omni Module, B112 Bass Module, and S118 Subwoofer. This modularity allows sound engineers to build systems of any size, tailoring the configuration to the specific requirements of each venue. Whether used in a ground-stacked setup or flown in a large array, the M46 ensures exceptional sound quality and coverage.
