PreSonus ULT18 Powered Subwoofer Speaker

Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus ULT12 and ULT15, the ULT18 subwoofer delivers a powerful, clear, and accurate low-end punch. With 2,000 watts of Class D power and a direct radiating, ported enclosure, it delivers the detailed low-frequency performance audio pros demand. Its custom 18-inch low-frequency transducer with 4-inch voice coil provides 7 mm of driver travel before over-excursion to push more air and bring more thump. A variable lowpass filter (rare in this class) lets you dial in upper frequency limit. The ULT18 also offers M10 fly points, ground stacking provisions, castor provisions, and a defeatable front-panel LED, making it a great choice for both mobile and install applications.

Six Year Warranty

We take our build quality seriously, and if anything goes wrong with them in your first six years of ownership (assuming you don't throw them in a swamp or anything like that) the repair or replacement is on PreSonus.

Guaranteed.
