Presonus ULT18 18" 2000W Active Subwoofer

Presonus ULT18  18" 2000W Active Subwoofer

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

The speaker inputs feature 2-combo XLR-1/4" connectors with direct outputs & polarity invert. The subwoofer's low-frequency transducer & voice coil provide 7mm of driver travel before reaching over-excursion. This permits 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.
