Yamaha DSR118W 800W 18" Powered Subwoofer

The DSR118W uses DSP technology to protect the amp and speaker - it has onboard 48bit AD/DA converters to turn the signal from analog to digital.

By going digital Yamaha have been able to include a range of technologies including their proprietary FIR-X tuning system which automatically optimizes the frequency and phase response.

Many rock bands gave this positive customer reviews, as did people who already had Yamaha DSR powered FOH speakers. There were also a few mobile DJs that rated this highly, but not as many as the others mentioned above. A commonly cited compliment is that these have a good punchy sound.


Some people complained a bit about the heavy weight and a couple of reviewers said it would have been nice to include manual control over the crossover - this is handled automatically.


The heavy build seems to have made the Yamaha DSR118W quite durable with no reports that I could find of the enclosure wearing out or getting easily damaged. In addition to pairing these with Yamaha FOH speakers (Tops) I've also seen reports of people happily using them with QSC, JBL, and even one case of using them with a Bose Compact L1 system.
