Yamaha CXS18MKIII 18" Passive Subwoofer

For applications where low-frequency output has to fill the room, the CXS18 mk3 is the anchor. An 18" long-excursion driver with a 4" voice coil and 1000W PGM power handling means it can sustain serious output levels without compression or distortion. Large venues, outdoor events, auditoriums, houses of worship, front ensemble reinforcement — this is the sub built for those jobs.

The bandpass enclosure delivers smooth, deep frequency response down to 35Hz in passive mode, extending to 32Hz when paired with compatible DSP. Large-diameter ports and a wide grille eliminate wind noise at high output. The polyurea-coated plywood cabinet is built to withstand the demands of professional touring and installation alike. Two-way handles and dual pole sockets (35mm and M20) handle rigging and configuration flexibility.

Pair it with a Yamaha PX or PC-D Series amplifier and you unlock dedicated DSP presets, cardioid mode for controlled stage-side SPL, and full system optimization. Works seamlessly with CXR mk3 full-range speakers as a matched system.
