Yamaha DXS18mk3 18" 2500W Powered Subwoofer

For musicians and engineers aiming to deliver a powerful, immersive live experience, consistent low-frequency extension is essential. The Yamaha DXS18mk3 18" 2500W powered subwoofer is engineered to deliver deep, authoritative bass with the clarity and control modern sound systems demand. A proprietary long-excursion 18" driver pairs with a 1500W RMS (2500W peak) Class-D amplifier and advanced 96kHz DSP processing to produce high-impact low end that remains tight and defined at higher output levels. Designed to pair seamlessly with Yamaha DXRmk3 loudspeakers, the ideal bandpass cabinet structure reduces unwanted noise while maintaining focused bass response. Combined with durable plywood construction and flexible system controls, the DXS18mk3 subwoofer delivers reliable low-frequency performance for demanding live sound environments.

Advanced DSP Control and System Optimization

The DXS18mk3 features a rear-panel LCD interface with intuitive encoder control for fast access to EQ, crossover, delay and routing parameters. Yamaha’s D-XSUB processing provides selectable presets, including NORMAL mode for balanced performance and XTENDED LF mode for extended low-frequency reproduction. A 96kHz internal DSP engine ensures high output with clarity and low latency, while cardioid mode with multiple units helps reduce stage-side bass buildup and improve monitoring accuracy. These tools allow engineers to quickly optimize system performance across varying venues and applications.

High-Power Amplification and Proprietary Driver Design

A newly developed 2500W Class-D amplifier powers Yamaha’s proprietary long-excursion 18" transducer with a durable 4" voice coil. This high-efficiency design delivers deep, controlled bass while maintaining consistent performance during extended use. The optimized bandpass cabinet structure with large-diameter ports minimizes wind noise and cabinet resonance, helping the subwoofer maintain clarity and punch during demanding performances.

Durable Construction and Flexible Deployment

The high-grade plywood enclosure is finished with a rugged polyurea coating that protects against impacts during transport and setup. Large two-way handles support comfortable lifting and positioning, while optional casters simplify load-ins for mobile systems. Dual pole sockets compatible with 35 mm and M20 poles allow flexible system configuration, whether supporting main loudspeakers or integrating into portable rigs.

Wireless Control and Real-World Workflow Features

Bluetooth connectivity enables control through Yamaha’s D-Remote app, allowing users to adjust levels, EQ, delay and presets from iOS or Android devices. The app also provides system monitoring, temperature alerts and scene recall for streamlined operation. Optional protective covers help guard against dust and weather, while cardioid configuration support and flexible mounting options make the DXS18mk3 18" subwoofer a practical solution for mobile DJs, bands and production crews seeking powerful, professional low-frequency reinforcement.
