Sound Changes Everything

Countless variables, and often pure luck, can factor into pulling off a memorable, even life-altering performance. Some you can control, others you cannot, but CXS mk3 Series passive subwoofers take luck out of the equation, offering outstanding performance, flexibility, and reliability for professional environments that put a premium on their bass sound. With an acoustic design that consistently delivers linear VLF performance, the highly-durable, Polyurea coated enclosure houses Yamaha’s own long-excursion, high-performance speaker unit, and features an ideal bandpass structure that ensures smooth and deep frequency response—even at higher outputs. With the CXS mk3 Series reliably delivering your bass with serious power and startling precision, you’ll never have to question if your bottom end performance can rise to the occasion when you need it most.

1 - Yamaha Proprietary Long-Excursion & High-Durability Speaker Units
All series models come equipped with Yamaha’s own customized, long-excursion speaker units specifically designed for subwoofers. The 18” model features a 4” voice coil, while the 15” and 12” models employ 3” voice coils, ensuring high durability.

2 - Ideal Bandpass Structure
Series enclosures adopt an ideal bandpass structure, significantly reducing unwanted noise even at high outputs. The combination of large-diameter ports and a wide high-performance grille significantly eliminates wind noise, enabling powerful, clear, and deep sub-bass reproduction.

3 - High-Performance Plywood Cabinet with Durable Polyurea Coating
The cabinet exterior employs a robust, scratch-resistant polyurea coating, protecting the enclosure from impacts during transport, installation, and removal. Power and High-Performance DSP That Unlock Performance

Advanced features that improve the user's workflow

Intelligent processing to maximize system performance
When used in combination with Yamaha PX* and PC-D Series amplifiers or other compatible signal processors, CXS mk3 series subwoofers can take full advantage of dedicated speaker processor tuning settings. (*Supported firmware is Ver 1.66 or later.)

Cardioid Mode
Low frequencies are typically non-directional, resulting in equal sound pressure levels on both audience and stage sides. When two or more CXS mk3 units are used in combination with Yamaha PX and PC-D Series amplifiers or other compatible signal processors, the cardioid mode enables more effective bass control by efficiently increasing audience-side output while simultaneously reducing stage-side sound pressure for optimized monitoring performance.

Dual Pole Socket
For enhanced convenience, the DXS/CXS mk3 series is equipped with pole sockets compatible with both 35 mm diameter and M20 threaded speaker poles.

Multi-Function Speaker Covers
Optional speaker covers are available for all models, protecting speakers from scratches, dust, and unexpected weather during transport or storage.

Optional Wheel Kit & 2-Way Handle
All DXS/CXS mk3 models support optional casters with radial ball bearings for vibration-free performance during operation. The two-way handle design ensures comfort during both transport and installation.
