PreSonus ULT18 18" Active 2000w Subwoofer

Add exceptional punch and power to your live sound system with the PreSonus ULT18 active subwoofer. With an 18" woofer bolstered by an impressive 4" voice coil and driven by 1,000 watts RMS of Class D power, the ULT18 delivers powerful bass performance. Use the variable lowpass filter to match it to virtually any set of main speakers. For low-visibility operation in a permanent installation, the front-panel LED can be defeated. Complete with a polarity invert switch and dual XLR/TRS combo inputs, the PreSonus ULT18 is a versatile active subwoofer that we can recommend for a wide range of PA applications.

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.
