Written by

Anna Colombo

HK Audio’s PR:O is a range of passive monitors constructed with real wood and featuring a classic design. Equipped with M8 rigging points, they are easy to fly and can stand even challenging custom installations. Great for live music as well as speech, they are a must-have in your touring equipment. 

The PR:O 15 X feature a 15” woofer delivering outstanding low-end response and high SPL. 
They work perfectly as standalone, with no need for a subwoofer, and they’re also great as monitors.


  • 800-Watts passive speaker system
  • 15” woofer and 1” tweeter for outstanding low-end and high frequency response
  • Feedback resistant
  • Equipped with M8 rigging points for easy installation
  • dimensions: 470 x 615 x 445 mm
  • weight: 21 kg


The PREMIUM PR:O series of passive cabinets consists of six full-range models: the PR:O 8, PR:O 10 X, PR:O 12, PR:O 12 M, PR:O 15, and PR:O 15 X, and two subwoofers, the PR:O 210 S and the PR:O 18 S. Constructed in a tried-and-true way with real wood and featuring a classic timeless design, these cabinets offer quality made in Germany and deliver excellent live music performance. Equipped with M8 rigging points, the full-range models are easy to fly and therefore suitable even for acoustically challenging custom installations. They also render speech with amazing clarity. 

There is a specially designed x-over integrated in the subwoofers which provides the correct frequencies to the mid/high units connected via the Satellite Out, thereby ensuring a clean separation without phase-shifting and striking the right balance between the mid/high unit and subwoofer. The system crossover also allows the subwoofer and mid/high unit to be operated with just one power amplifier channel. In systems, therefore, the recommended output of the power amplifier used depends on the subwoofer used. It is generally recommended to select a power amplifier output equal to or greater than the nominal power handling capacity (RMS, see technical data) of the cabinet to be driven to avoid distortion.

PR:O 15 X

This multifunctional 15"/1" cabinet delivers rich low-end response and high SPL. Remarkably feedback-resistant and amazingly articulate, it also serves users well as a monitor.
