Thomann’s cardioid-pattern installation at Tonhalle D\u00fcsseldorf delivers powerful reinforcement while protecting classical acoustics <\/em><\/p>\n\n\n\n

\n\n\n\n

D\u00fcsseldorf, Germany — October 2025 <\/strong>— One of Germany’s most acoustically revered concert halls has been transformed. Originally built in 1926 as a planetarium, Tonhalle D\u00fcsseldorf was converted into a concert hall during the 1970s and has since earned worldwide recognition for its exceptional natural acoustics. Today, the venue serves as home to the D\u00fcsseldorf Symphony Orchestra while hosting an eclectic mix of classical, rock, pop, comedy and cabaret performances. But when the hall’s aging sound system began experiencing critical failures, Tonhalle faced the urgent challenge of installing a world-class audio system worthy of a venue approaching its centennial without compromising its legendary acoustic integrity.<\/a><\/p>\n\n\n\n

The solution came through a competitive EU-wide public tender won by Integrator Thomann Audio Professional. Following a system design developed by consultancy firm B\u00fchnenplanung Walter Kottke Ingenieure (BWKI), integrator Thomann Audio Professional executed the installation of a comprehensive L-Acoustics solution that positions Tonhalle D\u00fcsseldorf to attract the world\u2019s most demanding artists and production teams. <\/p>\n\n\n\n

L2 Cardioid Pattern Wins the Day <\/strong><\/p>\n\n\n\n

The technical brief was uncompromising. Tonhalle D\u00fcsseldorf required a powerful, rider-friendly sound system that could satisfy touring engineers across every genre while respecting the hall’s classical music heritage. During BWKI\u2019s system design evaluations in consultation with Tonhalle and L-Acoustics, the L-Acoustics L2 quickly emerged as the optimal solution.  <\/p>\n\n\n\n

“L2 was our recommended route for two compelling reasons: its relatively compact design and, perhaps more importantly, its cardioid dispersion pattern,” explains Florian Denzler, Head of Department, Sound and Theatre Technology at Thomann. “Cardioid dispersion delivers significant acoustic improvements on stage, which is especially critical for classical concerts requiring sound reinforcement. Given Tonhalle D\u00fcsseldorf’s strong classical programming alongside its need to accommodate every genre, L2 was the obvious choice.” <\/p>\n\n\n\n

\u201cFrom the beginning, our objective was to preserve Tonhalle\u2019s pristine acoustics while introducing a rider-compliant reinforcement system,\u201d adds J\u00fcrgen Meyer, project lead at BWKI. \u201cL2\u2019s cardioid capabilities gave us the control we needed to minimize stage spill and maintain the hall\u2019s celebrated natural sound field.\u201d <\/p>\n\n\n\n

The cardioid pattern proved essential for managing the complex acoustics of the venue’s centerpiece space: the dome-shaped Mendelssohn Hall. With 1,854 seats spread across a 36-meter diameter and soaring 30 meters high, this 17,000m\u00b3 volume presented formidable coverage challenges that conventional systems simply couldn’t address with the required precision. <\/p>\n\n\n\n

L2 Coverage Mapping Conquers Complex Venue Geometry <\/strong><\/p>\n\n\n\n

BWKI’s design process centered on Soundvision modeling to ensure comprehensive coverage throughout the architecturally challenging space. The planning phase, led by J\u00fcrgen Meyer at BWKI, in close collaboration with Martin Rode at L-Acoustics, leveraged Soundvision’s precision to account for every seat in the venue before a single cabinet was hung. <\/p>\n\n\n\n

“Soundvision was this project’s most important tool,\u201d notes Denzler. \u201cWe needed a system that we could deploy quickly and accurately. This wouldn’t have been possible without Soundvision. ” <\/p>\n\n\n\n

The team faced additional complexity beyond coverage mapping. During classical performances where the main sound system often remains unused, the subwoofers needed to disappear entirely from sight. The solution was to mount the subwoofers on a chain hoist system above the stage, allowing them to be lifted through a flap in the sound cover when visual aesthetics take priority over reinforcement. <\/p>\n\n\n\n

The project moved fast. The team had just two months to design the entire system between November 2024 and January 2025. Tendering and award wrapped up in February, then construction ran from mid-July through the end of August this year. <\/p>\n\n\n\n

Comprehensive L Series Configuration Delivers Flexibility <\/strong><\/p>\n\n\n\n

The final installation showcases the versatility of L-Acoustics L Series. The main PA comprises one hang of L2<\/a> and L2D<\/a> per side, with a center array of three KS21i<\/a> subwoofers in cardioid configuration. Eight X4i<\/a> are integrated into the stage edge for in-fill, while side-fill is managed with two hangs of one A10i Focus<\/a> over two A10i Wide<\/a>. Under-balcony coverage is handled by 12 X6i<\/a> speakers while one A10i Focus and one A10i Wide per side, deliver sound to seating behind the stage. Six LA7.16i<\/a> amplified controllers power the complete system.\u00a0<\/p>\n\n\n\n

The installation operates on Milan-AVB. Two distinct system configurations accommodate different stage sizes, accessible through a Universe Control system for seamless transitions between performance types. <\/p>\n\n\n\n

To further streamline daily operation, Thomann integrated its Universe media control platform, enabling the Tonhalle team to recall multiple amplifier preset scenarios at the touch of a button. Presets such as \u201cLarge Stage\u201d \u201cSmall Stage\u201d allow the technical staff to adapt the system quickly ensuring intuitive operation even for non-technical users. <\/p>\n\n\n\n

With the new L-Acoustics installation now operational, Tonhalle D\u00fcsseldorf has positioned itself to meet the technical expectations of world-class touring productions. The system’s rider-friendly configuration addresses the technical requirements that make venues attractive to touring productions, opening new programming possibilities as the hall approaches its centennial celebration. <\/p>\n\n\n\n

“Since the new system was designed with Tonhalle D\u00fcsseldorf’s primary requirement in mind – the ability to meet a variety of technical riders – we’re confident it will attract the large number of performers and external organisers the hall deserves,” Meyer concludes.  <\/p>\n\n\n\n
