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. 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.
As with the ULT12 and ULT15, you can defeat the front power-indicator
LED for low-visibility installs. ULT18 loudspeakers were designed by
WorxAudio®, the commercial loudspeaker division of PreSonus.
