Yamaha CXS15 MK3 Description

The Yamaha CXS15 MK3 is the mid-size model in Yamaha’s latest CXS MK3 passive subwoofer series, offering a practical balance of output, size, and portability. Designed for professional environments where dependable bass performance matters, it delivers deep and powerful low-frequency response while maintaining clarity at higher output levels.

Its 15-inch cone woofer uses Yamaha’s proprietary high-durability, long-excursion design with a 3-inch voice coil, helping the subwoofer handle demanding program material with confidence. The ideal bandpass structure works together with large ports and a high-performance grille to reduce wind noise and unwanted cabinet resonance, resulting in cleaner and more focused sub-bass reproduction.

The plywood cabinet is acoustically optimized for sound quality and finished in a durable black polyurea coating for added protection during transport, setup, and teardown. For system integration, the Yamaha CXS15 MK3 includes dual speakON NL4MP connectors and dual pole socket compatibility with both 35 mm and M20 threaded poles, making it easy to pair with compatible full-range speakers.

When used with Yamaha PX or PC-D Series amplifiers or other compatible signal processors, the CXS15 MK3 can take advantage of dedicated tuning settings for improved system performance. It also supports cardioid configurations when multiple units are deployed, helping improve audience-side bass impact while reducing low-frequency energy on stage.
