Historic Tonhalle Düsseldorf installs L-Acoustics L2

When Tonhalle Düsseldorf needed a new system worthy of its performances, Thomann delivered with an L-Acoustics L2 setup

Originally built in 1926 as a planetarium, Tonhalle Düsseldorf in Germany was converted into a concert hall during the 1970s. Now home to the Düsseldorf Symphony Orchestra, the space hosts a mix of classical, rock, pop, comedy and cabaret performances. Facing an ageing sound system, the venue turned to Thomann Audio Professional and its proposed installation of L-Acoustics L2 for a modern upgrade.

Tonhalle Düsseldorf required a powerful sound system that could satisfy touring engineers across every genre. The system also had to respect the hall's classical music heritage. After evaluating the space, L-Acoustics L2 quickly emerged as a solution.

"L2 was our recommended route for two compelling reasons: its relatively compact design and, perhaps more importantly, its cardioid dispersion pattern," explained Florian Denzler, head of department for sound and theatre technology at Thomann. "Cardioid dispersion delivers significant acoustic improvements on stage, which is especially critical for classical concerts requiring sound reinforcement."

With 1854 seats, this concert hall presented formidable coverage challenges that conventional systems couldn't address. The design process centred on Soundvision modelling to ensure comprehensive coverage throughout the space.

Nonetheless, the team faced additional problems beyond coverage mapping. During classical performances, when the main system might not be used, the subwoofers needed to be hidden from view. The solution was to mount them on a chain hoist above the stage, allowing them to be lifted through a flap at any time.

The system now features L-Acoustics’ L Series with L2 and L2D arrays, KS21i subwoofers, A10i and X Series fills, all powered by LA7.16i amplified controllers. Thomann’s Universe Control platform enables quick configuration changes and preset recalls, allowing the Tonhalle team to adapt easily between performance types.

With the new L-Acoustics installation now operational, Tonhalle Düsseldorf is ready to meet the needs of touring acts. The system’s usability has now opened new programming opportunities ahead of the venue’s centennial. This upgrade delivers the same clarity and control showcased in L-Acoustics’ work on Andrea Bocelli’s orchestral tour.
