Low-end punch you can hear and feel
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 (peak) of Class D power and a direct radiating, ported enclosure, it has all the muscle needed for the detailed low-frequency performance audio pros demand. Its custom 18-inch Kevlar 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.
Extensive controls enable customized performance
To provide maximum versatility, the ULT18 offers several important user controls. Unlike most subwoofers in this class, the ULT18 features a variable lowpass filter that enables you to accurately dial in the crossover transition between the subwoofer and your full-range system. Two DSP presets provide extended low-frequency performance or a more natural response to suit a variety of applications, and of course you get polarity reverse. A Mono Mode function is also provided to simplify cabling multiple mono subs in a stereo system.
Equally at home in mobile and installed systems
Like the full-range ULT12 and ULT15 loudspeakers, the ULT18 has a rugged, tour-grade birch enclosure for the distinctive performance characteristics that only wood can offer. A locking IEC power connector, M10 rigging points, integrated castor provisions, and ground-stacking provisions, making it a great choice for a wide variety of mobile and install applications. Two combo XLR and ¼” TRS line-level inputs with level control and throughputs are provided to connect full-range systems or multiple subwoofers in larger systems. As with the ULT12 and ULT15, you can defeat the front power-indicator LED for low-visibility installs.
