Yamaha RS18-PT Nexo RS, 18" Touring Subwoofer System

Powerful 18-Inch Subwoofer for Touring and Large-Scale Applications
The Yamaha RS18-PT is a high-output, low-profile 18-inch touring subwoofer designed to provide deep, controlled bass in demanding live sound environments. Featuring dual long-excursion neodymium drivers, this subwoofer extends system response down to 30Hz, delivering powerful low-end reinforcement for concert venues, festivals, and touring productions. Built for maximum performance, the RS18-PT utilizes NEXO's innovative RAY SUB technology to enhance bass projection and efficiency.

Advanced RAY SUB Technology for Optimal Bass Projection
Equipped with NEXO’s proprietary RAY SUB technology, the RS18-PT optimizes the phase alignment of its radiating surfaces to ensure uniform and efficient bass reproduction across its entire frequency range. This results in an average of 5dB additional gain in the forward direction while minimizing unwanted rear sound energy. Whether used as a standalone unit or in an array configuration, this subwoofer offers a level of control and clarity that surpasses conventional designs.

Flexible Configuration for Omni and Directional Bass Coverage
One of the RS18-PT’s key advantages is its ability to be configured for different polar patterns. When positioned with its speakers facing the audience, it functions as an omnidirectional subwoofer. However, by rotating the cabinet sideways or upwards, users can achieve highly directional bass coverage. This flexibility allows for improved system tuning and room adaptation, making it an ideal solution for live sound reinforcement in a wide range of venue sizes and layouts.

Cardioid Subwoofer Design for Reduced Stage Noise
Designed with a cardioid pattern capability, the RS18-PT effectively reduces rear sound levels, minimizing reflections from side and rear walls. This feature is essential for live performances, where excessive low-frequency energy behind the subwoofer can cause stage rumble and microphone feedback. By controlling bass dispersion, the RS18-PT ensures cleaner, more defined low-end without interference in on-stage monitoring.

Durable Construction for Touring and Installation Use
Built to withstand the rigors of professional touring, the RS18-PT features a robust enclosure made from premium Baltic birch plywood with a protective textured coating. The aerodynamic profiled vents are engineered to reduce port noise by 20dB, ensuring distortion-free bass at high SPL levels. The subwoofer integrates seamlessly with NEXO’s full product line and is optimized for use with NXAMP digital controllers for maximum efficiency and protection.
