Yamaha MSUB18-I Nexo Geo M Subwoofer

Powerful Installation Subwoofer for GEO M12 Systems
The Yamaha MSUB18-I is a high-performance installation subwoofer designed to integrate seamlessly with NEXO’s GEO M12 line array systems. Built to deliver deep, impactful bass in professional audio environments, this compact yet powerful subwoofer extends low-frequency response while maintaining a clear and controlled output. Whether installed in a concert hall, theater, or house of worship, the MSUB18-I ensures rich, immersive sound reproduction.

Optimized for Fixed Installations
Unlike the touring version, the MSUB18-I is specifically engineered for permanent installations, featuring an acoustic fabric grille and cable gland connectors for a clean, professional look. The durable black finish allows for discreet placement, while custom RAL color options enable seamless integration into any venue’s design.

Extended Low-Frequency Response with High Output
The MSUB18-I houses a powerful 18-inch Neodymium driver, designed to handle high power levels while maintaining tight and punchy bass. Its advanced band-pass cabinet design, combined with a quadratic profiled port, allows for deep bass extension down to 30Hz, delivering an authoritative low-end presence suitable for demanding applications.

Cardioid Configuration for Precise Bass Control
To ensure maximum low-frequency control, the MSUB18-I supports both front and rear connectivity for cardioid deployment. This minimizes unwanted low-end spill on stage and into adjacent areas, improving overall sound clarity and reducing noise interference in sensitive environments.

Rugged Construction for Reliable Performance
Crafted from high-quality Baltic birch plywood, the MSUB18-I is built for long-term reliability in fixed installations. Its robust construction reduces resonance and vibration, ensuring clean and accurate sound reproduction. The integrated rigging hardware allows for flexible mounting configurations, whether in ground-stacked or flown setups.

Seamless Integration with NXAMP Amplification
The MSUB18-I is optimized for use with NEXO’s NXAMP4x4MK2 amplifier (sold separately), providing precise DSP control and efficient power management. This ensures consistent performance, easy system calibration, and streamlined operation for professional installations.
