It doesn't matter whether you are playing pre-recorded music or performing live for a audience, you'll love the massive low end power and clarity that the Yamaha DXS18 powered subwoofer adds to your system.

Great bass sound speaks for itself. Period.

Like your music to have a powerful low end presence?

The Yamaha DXS18 will provide you with the chest thumping bass you desire, and it will do it with outstanding clarity. Featuring a high efficiency Class-D amplifier and a customised woofer housed in a sturdy plywood band pass enclosure, the DXS18 will produce an impressive 1020 watts of power, all without breaking a sweat!

Of course, this sub will also work well with other brands of speakers.

Yamaha, together with high end touring class speaker company Nexo, worked tirelessly to develop subwoofers with this level of versatility, dependability, and power. If you know Nexo, you'll know they mean business.

High-Efficiency 1020W Class-D Amplifiers

The DXS18’s high-performance Class D amplifier is capable of producing up to 1020 watts of distortion free power, and a maximum SPL of 136 dB is delivered with exceptional clarity and accuracy. 

Custom Designed Transducer

The high-output woofer of Yamaha DXS18 features a 4" voice coil magnet and delivers powerful, well-defined, low-frequency bass with no distortion. 

Band-Pass Type Enclosure

The DXS18 enclosure is a band-pass design, that virtually eliminates unwanted vibrations and noise that could otherwise compromise your sound.

Yamaha have also designed a very durable, yet lightweight, plywood enclosure which when combined with the band-pass configuration tested better than the traditional bass-reflex design and reduced to virtually nil, making it possible to achieve a higher SPL at the best possible clarity.

Durable, Portable, and Road-Ready.

The ergonomic and compatible features of the DXS18 just made your system setup and transport a whole lot easier. This sub is lightweight, has handles in exactly the right spot, and features a dual pole mount socket for deploying a full range speaker above it.

Yamaha have also provided optional weather proof cover and a wheel kit to make it even easier for you to move around (sold separately)

Rugged coating for superior protection

The Yamaha DXS18's enclosure exterior features a durable Polyurea coating, with extremely high damage resistance to protect the cabinet from scratches, bumps, or severe weather conditions, maintaining a professional appearance for years to come.

Dual pole socket

For additional flexibility configuring your speakers, the DXS18 comes equipped with a dual pole socket that accommodates both 35 mm diameter speaker poles and M20 screws.

Cardioid Mode

Because low frequencies can be omni-directional, controlling the output directivity of a system’s bottom end can be a challenge, with the sound pressure hitting the stage often being equal to that of its intended FOH audience.

For setups consisting of two or more DXS18 subwoofers, selecting the newly developed Cardioid Mode effectively decreases stage-side sound pressure while increasing the bottom-end output directed towards the audience.

This results in a reduces sound on stage that may intrude on the stage monitoring, and a more pronounced bass at higher SPL for the audience.

D-XSUB Bass Processing

Powerful D-XSUB processing gives you total control of your low frequency.

NORMAL mode gives you the ideally balanced low-frequency response, while BOOST mode provides a tighter and more focused bass.

XTENDED LF mode drops the low-end frequencies down even further for thunderous bottom end that delivers a low frequency extension unheard of from smaller cabinets.

Take your full-range system to the next level with the power and versatility of DXS18 active subwoofer.

Selectable X-OVER(80/100/120 Hz)

Crossover switching allows users to seamlessly match the DXS subwoofer with any of Yamaha’s full-range powered speakers by selecting the cutoff frequency best suited to the models in their speaker array (up to 120 Hz).

Easy Integration with your Equipment

It's easy to add the DXS18 powered subwoofer to your Yamaha loudspeaker system, or any other powered system for that matter. The dual XLR inputs let you connect your mixer, crossover system, or main speakers, and parallel XLR outputs make it easy to add additional subwoofers for even more ground-shaking bass reinforcement.
