Our take on the Yamaha DXS 18

What you need

Whether you're looking for PA gear for a place of worship or a punk band, there's one thing we all need: bass. Big, rich, booming bass. Yamaha understands, and created the DXS Series of powered subwoofers to give you the bass you want.

Powerful and efficient

Yamaha's engineers placed a high-efficiency 1020-watt Class D amp and an 18" high-output woofer in a sturdy plywood bandpass enclosure that's optimized for impressive output. Yamaha's sophisticated low-frequency processing means this sub can produce impressively loud bass at sound pressure levels up to 136 dB. This sub matches up perfectly with Yamaha's DSR and DXR powered speakers, and the sub's built-in pole sockets make it easy to mount a speaker directly over the sub.

Sophisticated processing

You can set the sub's crossover point to 80, 100, or 120 Hz so it'll match up with just about any powered speaker. The DXS18 also features Cardioid Mode, in which two or more DXS18s can be combined in a cardioid sound pattern which helps directionalize the sound. In addition, Yamaha's D-XSUB Processing offers three different bass modes, so you can adapt the sub to live bands, DJs, and other applications. This sub will add depth and richness to any show, whether it's a small club, a medium-sized hall, or even outdoors. You'll get the sound you want in a sub that's still small enough to fit into most vehicles.

This sub has all the bass I need. I have 2 of them and probably for most parties I'll only need one.I wanted a powered sub that sounded like my old 160 pound cerwin vegas that I sold, these were pretty close. 50 pounds lighter and a lot smaller. Awesome.

Product Research


Powered Subwoofer: The DXS series power subwoofer features a customized, high-power handling 18" woofer with superior damping and a 4" voice coil magnet, for a clean, accurate delivery of the massive power produced by its 800W RMS/1020W Peak Class-D high-efficiency amplifier. The DXS series powered sub has an all-new band-pass design that produces extremely high SPL by drastically reducing the distortion.

D-XSUB Processing: D-XSUB is a newly-developed processing technology exclusively for subwoofers that dynamically controls the low frequency range. Powerful D-XSUB processing allows you to choose from either Normal, Boost or Xtended LF settings. You can select either mode in accordance with various applications and musical genres.

  • Normal mode gives you the ideally balanced low-frequency response.
  • Boost mode provides a more tight and focused bass.
  • Xtended LF mode drops the low end frequencies down-even further for thunderous bottom end that delivers.

Low-Pass Filter: The powered sub features a variable low-pass filter. You can set the low-pass filter's cutoff frequency at 120Hz, 100Hz, or 80Hz. The filter will cut the frequency components above the specified threshold. If you are using the DXS series sub along with a DXR series PA speaker, match this frequency to DXR's HPF switch setting.

Polarity Switch: In most cases, the Normal setting is recommended. However, the Inverted setting may improve low-range response, depending on the type and location of the speaker system. Try both settings and select the one that produces the best low-end sound.

Balanced Inputs & Outputs: The powered subwoofer features a balanced stereo XLR input for connection to a DXR-series speaker's "through"-output or the balanced XLR output of a mixer. The balanced stereo XLR outputs allow the powered sub's input signal to be passed through unaffected to another sub, mixer, or component.

DSP-Controlled Advanced Protection System: Powerful protection circuits ensure secure protection in the speaker unit, amplifier unit, and power supply unit. This
protection functionality promotes optimal performance of each component and optimum reliability without distortion even in challenging environments. LED indicators will light and the speaker output will be muted in the following situations.

  • If amplifier overheating is detected
  • If DC output is detected
  • If over-current is detected
