Yamaha CXS18MK3 18" Passive Subwoofer

Yamaha CXS18 mk3 Passive Subwoofer
Deep, High-Impact Bass for Professional Sound Reinforcement
The Yamaha CXS18 mk3 Passive Subwoofer is engineered to deliver powerful, extended low-frequency performance for professional live sound systems. Designed for touring productions, concert venues, clubs, theaters, houses of worship, and permanent installations, the CXS18 mk3 combines exceptional output, outstanding durability, and precise bass reproduction in a compact, road-ready enclosure.
Its acoustically optimized band-pass cabinet maximizes low-frequency efficiency while minimizing unwanted port turbulence and cabinet resonance, resulting in deep, tight bass that remains clean and controlled even at high output levels. The premium plywood enclosure and rugged Polyurea finish provide exceptional durability for demanding rental, production, and touring environments.
When paired with compatible Yamaha PX Series or PC-D Series power amplifiers, the CXS18 mk3 supports Yamaha's advanced Cardioid Mode processing. This technology directs low-frequency energy toward the audience while reducing bass buildup on stage, improving overall system clarity and providing a better monitoring environment for performers.
Whether you're expanding an existing Yamaha PA system or designing a new professional sound reinforcement system, the Yamaha CXS18 mk3 delivers the performance, reliability, and low-frequency impact demanded by today's audio professionals.
