Yamaha DXS18

With powerful deep bass and precise reproduction, this active 18-inch subwoofer adds a solid foundation to your sound system. The bandpass enclosure made of robust meranti plywood is not only durable but also acoustically optimized to deliver clean results even at high levels. A tough polyurea coating reliably protects the surface from wear – ideal for frequent transport and use under demanding conditions.

Inside, a high-performance Class-D amplifier with 800 watts continuous power (1,020 watts peak power) effortlessly reproduces low frequencies between 32 Hz and 120 Hz. Combined with the large 18-inch driver with a 4-inch voice coil, this ensures punchy, well-defined bass. Thanks to Yamaha’s D-XSUB processor, you can flexibly adjust the frequency range – either for extra deep low-end emphasis or balanced standard playback.

Especially practical is the cardioid mode, which reduces sound pressure to the sides and behind the speaker while boosting bass energy forward to the audience. This way, you maintain controlled acoustics even on stage. Dual XLR inputs and outputs allow the subwoofer to integrate seamlessly into existing systems or be paired with additional units. The integrated dual pole mount (35 mm and M20) offers flexible setup options.

With a maximum sound pressure level of 136 dB SPL, this model has enough headroom for medium to large venues. The natural convection cooling ensures silent operation without disturbing fan noise. The combination of high output power, flexible connectivity, and a rugged enclosure makes this subwoofer a reliable addition for live performances, installations, or mobile sound systems.
