PreSonus ULT15 PA Loudspeakers (15")
Ultra Long Throw with Even Coverage Throughout. 2-way Active Sound-Reinforcement Loudspeakers

ULT: Ultra Long Throw. PreSonus® ULT15 active loudspeakers combine the widest horizontal dispersion of any loudspeaker in their class with a focused vertical dispersion for an ultra-long throw. The result is even coverage throughout the space, enabling the audience to hear clearly wherever they are. Featuring PreSonus’ proprietary Pivot X110 horn, a custom 15-inch low-frequency driver, and plenty of biamped Class D power in a lightweight design with the performance characteristics that only wood can offer, ULT15 loudspeakers deliver first-rate speech intelligibility and natural music reproduction. This makes them a great choice for both mobile use and permanent installations.

Wide horizontal coverage, narrow vertical dispersion, and superior throw. The ULT15’s custom-designed Pivot X110 rotatable horn combines ultra-wide horizontal coverage (110°) for broad coverage with focused vertical dispersion (50°) for superior throw. The result is a loudspeaker that can fill the room without introducing early reflections that muddy the sound. In addition, the Pivot X110 horn’s large size enables it to control the dispersion pattern lower in the frequency range than smaller conventional horns, so it maintains more consistent gain on- and off-axis, ensuring that the audience at the sides has the same listening experience as those in front. The result is sound reproduction that fills the entire room, evenly providing optimal audio.

Mounts horizontally or vertically for a variety of applications. The Pivot X110 horn can be rotated 90˚, so the ULT15 can be mounted in a horizontal configuration while still maintaining its 110˚ x 50˚ coverage pattern. Along with its compact size, this makes the ULT15 an ideal center-channel speaker for an LCR system or an under-balcony fill. Rotating the Pivot X110 horn can also help fix FOH issues in tall, narrow venues by minimizing early reflections and providing more directed coverage. Add the ULT15’s multi-angle enclosure and presets for live performance, floor monitor use, and music playback, and you have an extremely versatile loudspeaker that is equally at home at front-of-house and as a stage monitor.

Plenty of power and I/O. The ULT15 is supplied with more than enough power and I/O to handle a wide variety of applications and environments. Its 15-inch woofer is driven by a 500W (continuous), Class D power amp, while the 1.75-inch Pivot X110 horn receives 150W. (Peak power is rated at 1,000W and 300W, respectively.) You get two combo XLR and ¼” TRS inputs: a mic/line input with PreSonus’ acclaimed XMAX mic preamp and a line-level-only input. The inputs have independent level control, allowing up to two audio sources to be mixed internally and summed to a balanced XLR output for "daisy-chaining" multiple units. A separate direct output for the line input channel provides additional flexibility.

Designed by WorxAudio. ULT15 loudspeakers were designed by WorxAudio®, the commercial loudspeaker division of PreSonus.
