Wide horizontal coverage, narrow vertical dispersion, and superior throw.

Get 110˚ x 50˚ dispersion in a super-affordable 2-way loudspeaker! PreSonus® ULT15 active DSP loudspeakers combine the widest horizontal dispersion of any 15-inch, 2-way loudspeaker in their class with focused vertical dispersion for ultra-long throw.

The Pivot X110 horn can be quickly “field-rotated” rotated 90˚, so ULT loudspeakers can be mounted in a horizontal configuration while still maintaining a 110˚ x 50˚ coverage pattern. This makes ULTs ideal center-channel speakers 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.

Plenty of power and I/O.

The ULT15 packs 1,300 watts of Class D power (1,000W LF, 300W HF) with 119 dB of dynamic range and over-current, DC, over/under-voltage, over-temperature, and high-frequency protection. The mic/line input with XMAX mic preamp and the line inputs have separate level controls, Mix Out allowing up to two audio sources to be mixed internally and summed to a balanced XLR output for daisy-chaining multiple units. You also get both Mix and Direct Outputs. Other key features include three application presets for live performance, floor monitor use, and music playback; high pass filter select and Clip, Overload LEDs; and defeatable front-panel power LED.
