Yamaha STM-B112 Bass Module

High-Powered Bass Performance for Demanding Applications
The Yamaha STM-B112 is a high-output bass module designed to deliver exceptional low-frequency performance in professional sound reinforcement applications. With a Neodymium high-excursion 12” bass driver and a 4” voice coil, this module provides up to 3000W of power for deep, impactful bass response. Whether used in concert touring, festival sound, or permanent installations, the STM-B112 delivers unmatched efficiency and output.

Hybrid Horn-Loaded Design for Maximum Efficiency
Unlike traditional front-loaded bass drivers, the STM-B112 features a hybrid horn-loaded design, optimizing efficiency and delivering up to 6dB more output in its frequency range. This ensures powerful and clear bass projection, making it an ideal choice for high-energy performances and large-scale sound applications. The bass module seamlessly integrates with other STM components for a cohesive and powerful sound system.

Innovative PistonRig™ and REDLock™ Rigging for Quick Setup
The STM-B112 is built with PistonRig™ and REDLock™ rigging technology, allowing a single operator to fly and secure the system safely and efficiently. The REDLock™ handle locks the front rigging points from the rear of the cabinet, enabling quick adjustments without the need for multiple operators. This streamlined rigging system ensures fast deployment and dismantling, saving valuable time during setup.

Compact Yet Powerful for Any Configuration
Designed to match the dimensions, weight, and center of gravity of the STM M46, the STM-B112 can be seamlessly integrated into modular configurations. This uniform format allows for flexible system design, making it easy to scale up or down based on venue size and performance needs. Despite its compact form factor, the bass module delivers a peak SPL of 141dB, ensuring robust and articulate bass reproduction.

Built for Professional Touring and Installation
Constructed with durability in mind, the STM-B112 is built for the rigors of touring and demanding fixed installations. The rugged injection-molded cabinet provides both strength and lightweight performance, making it easy to transport while ensuring long-lasting reliability. This module is an essential component for sound engineers and production companies looking for superior bass performance in a versatile and scalable format.
