Yamaha CXS12 MK3 Description

The Yamaha CXS12 MK3 is designed for users who need serious low-frequency performance in the most compact format of Yamaha’s passive subwoofer lineup. Its 12-inch long-excursion woofer with a 3-inch voice coil is housed in an optimized band-pass enclosure that helps reduce unwanted cabinet and port noise while delivering deep, clear, and controlled bass. This makes it a strong fit for portable PA systems, DJ setups, small live venues, and installed audio systems that need added low-end authority without taking up excessive space.

Yamaha engineers the CXS12 MK3 for smooth and reliable low-frequency reproduction, with a cabinet structure that supports linear very-low-frequency performance and minimizes turbulence at higher output levels. When paired with Yamaha PX or PC-D Series amplifiers or other compatible signal processors, the subwoofer can take advantage of dedicated speaker processor tuning settings for improved system integration and optimized performance.

The enclosure is constructed from plywood and finished with a durable black polyurea coating for long-term reliability in transport, setup, and daily use. Dual side handles make the cabinet easier to carry, while the integrated 35 mm and M20 pole sockets support flexible full-range speaker mounting. Optional SPW-1 wheels and the SPCVR-DXS123 cover add convenience for transport and protection.

For more advanced system design, the Yamaha CXS12 MK3 can also be used in cardioid configurations when combined with two or more matching units and compatible Yamaha amplification or processing. This makes it a versatile passive subwoofer for users who want compact size, strong bass impact, and flexible deployment options in a professionally tuned sound system.
