German football stadiums rely on HK Audio’s VORTIS 2 loudspeakers to ensure effective voice evacuation and life-safety announcements. Certified to EN 54-24, the system provides clear, intelligible communication even in high-noise environments, supporting compliance with regulatory requirements.
In the 2. Bundesliga, Böllenfalltor Stadion (SV Darmstadt 98), Olympiastadion Berlin (Hertha BSC), and Ursapharm Arena (SV Elversberg) use VORTIS 2 as part of their critical voice alarm systems. In the 3. Liga, Ludwigspark Stadion (FC Saarbrücken) has also implemented the system for life-safety purposes. Beyond professional leagues, historic multi-use venues such as Grotenburg Stadion in Krefeld have adopted VORTIS 2 to maintain safety standards.
VORTIS 2 is designed for outdoor applications and offers IP55 variants for dust and water protection. Its high maximum sound pressure levels ensure that announcements remain audible across large areas, supporting effective emergency management. HK Audio also provides planning support, simulations, and on-site commissioning to verify system performance.
With widespread adoption across professional and community stadiums, VORTIS 2 underlines the importance of reliable voice evacuation systems in protecting spectators.
