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 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.
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.
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.
