PreSonus ULT18 overview

  • 1Description

The ULT18 Active Sound-Reinforcement Subwoofer from PreSonus is an 18" custom woofer with a 4" voice coil driven by 2000W of Class-D power in a direct-radiating ported enclosure. Designed to complement any full-range PA loudspeaker, it can be used to deliver low-frequency performance in sound-reinforcement applications for live stage, theater, clubs, and more.

The speaker inputs feature two combo XLR-1/4" connectors with direct outputs and polarity invert. The subwoofer's low-frequency transducer and voice coil provide 7mm of driver travel before reaching over-excursion. This allows it to push more air and bring more thump. In addition, a built-in variable low-pass filter lets you dial in the upper-frequency limit.

Designed with M10 fly points, ground-stacking provisions, castor provisions, and a defeatable front-panel LED, the ULT18 active subwoofer is a suitable choice for both mobile or install applications.
