Ultra Long Throw with Even Coverage Throughout

ULT15: 2-way Active Sound-Reinforcement Loudspeakers

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.

 

Creating wide dispersion throughout a speaker’s bandwidth presents a challenge because as frequencies go higher, their wavelengths shorten, narrowing their dispersion. At low frequencies, loudspeakers tend to radiate consistently in all directions; at higher frequencies, they tend to beam the sound. So a conventional loudspeaker that is relatively flat on-axis radiates a different frequency spectrum when off-axis because the response is no longer frequency independent.

 

In contrast, the Pivot X110 horn achieves a wide (110˚), consistent horizontal coverage, while narrowly focusing the coverage in the vertical (50˚) so that the high-frequency content has a longer throw. The resulting pattern expands with constant spectral content throughout the coverage area and all the way to its edges.

 

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.

 

Normal Front-of-House

 

The 110˚ x 50˚ dispersion pattern makes the ULT12 and ULT15 ideally suited for mobile front-of-house use. The wide horizontal pattern provides even coverage across the room. The 50˚ vertical dispersion ensures ultra-long, focused throw. The result is sound reproduction that fills the entire room, evenly providing optimal audio.

 

Floor Monitoring

 

When flipped into floor monitor position, the ULT15’s horizontal dispersion pattern narrows to 50˚. As a result, the floor monitor’s energy is focused on a relatively limited area that won’t bleed over into either side, allowing each musician’s mix to inhabit a specific zone on the stage. At the same time, its 110˚ vertical dispersion allows a performer the freedom to move forward and back within their zone without sacrificing clarity.

 

Wide Room and LCR

 

When oriented horizontally, the ULT15’s compact size and rotatable horn provides a wide coverage pattern ideally suited as a center channel for an LCR system or an under-balcony fill. When used in an LCR system, the 110˚ horizontal dispersion provides more seamless and wider coverage than speakers using a traditional 75˚ axisymmetric or 90˚ dispersion pattern.

 

Tall Narrow Room

 

Rotating the Pivot X110 horn in a typical FOH situation can help to fix the typical issues found in a tall, narrow venue. By rotating the horn to create a 50˚ horizontal dispersion and a 110˚ vertical dispersion, problematic early reflections can be minimized and more directed coverage is provided.

 

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. Headquartered in Greensboro, North Carolina, WorxAudio has been at the forefront of loudspeaker development for the pro touring and contractor markets for the over 30 years. WorxAudio continues to embrace the latest technology, delivering innovative products and installation designs for professional clients, and their products can be found in prestigious facilities worldwide. So you can rely on ULT loudspeakers to deliver the top-quality professional performance and features that touring engineers and systems integrators need.

Hearing is believing.

With extra-wide horizontal and focused vertical dispersion, a rotatable horn, ultra-long throw, a wood enclosure, and ample Class D power, the ULT15 is an excellent solution for permanent installations. Yet it’s also portable, making it a top choice for tours and other mobile use. Best of all, it sounds great, delivering outstanding speech intelligibility and natural music reproduction, with even coverage throughout the space.
