HK Audio CONCERT SOUND is synonymous with professional, perfectly matched sound reinforcement solutions that deliver the best sound quality, high performance and unrestricted road capability.

CONCERT SOUND 2.0 expands the product family with new filter sets that impress with an optimised sound signature, improved usability and perfectly coordinated system coherence. A small download with a big impact!

New sound dimensions

Thanks to significant further development, CONCERT SOUND 2.0 offers a new, cross-product sound signature. Systems now sound fuller, bigger and more confident, offering even the most demanding listeners an unrivalled sound experience.

Low-mid beamsteering using all-pass filters ensures that all frequencies are evenly distributed throughout the entire listening area.

Easy operation for maximum focus on performance

The newly structured user guidance makes it easier and faster to set up the systems:

  • Reduced number of filters: Only one crossover frequency to the bass, one basic filter per top and optimised and customisable overlays (depending on the array length) make setup intuitive and efficient.
  • Time alignment: All system components are optimised so that the sound waves start synchronously at the front grilles of the speakers. In many cases, this eliminates the need for calibration – a real time saver for technicians.

A harmonious overall package: One family, one sound philosophy



The new filters have been extensively tested under live conditions and are now available for Lake and Armonía. Existing systems can be easily updated to CONCERT SOUND 2.0 and benefit directly from the new possibilities. Updated Ease files are also available to further facilitate planning and implementation.

CONCERT SOUND 2.0 offers a new level of sound quality, efficiency and flexibility that has been met with enthusiasm from technicians, artists and audiences alike.
