Perfect acoustic experience for the Swissporarena in Lucerne with AD-Systems

Perfect acoustic experience for the new Swissporarena in Lucerne

Beschallungskonzept Swissporarena Luzern
Switzerland – It’s not always possible to work on a building project of this class. However, the company Avidec AG and our Swiss partner Promedias contributed to the planning and building of the newly built football stadium in Lucerne.

Due to the operational requirements for the multi-purpose facility, which seats between 16,000 and 20,000 spectators, considerable measures had to be taken to optimize the reverberation time. In order to achieve an optimal reverberation time and ensure uniform sound and good speech transmission to all seats, a loudspeaker system with extremely precise directivity and above-average sensitivity was required.

Optimal reverberation time

For this reason, Avidec AG planned the complete sound system in close collaboration with the client and used our Stium high-performance loudspeaker system for its implementation. Installed were 70 pieces of Stium loudspeakers paired in horizontal orientation and the evenly distributed on the straight lines and curves of the arena. For the VIP area, which is striking through its large glass fronts, 19  of our iFlex10 are controlled separately from the Stium System. The loudspeaker systems achieve an astounding speech intelligibility index of up to 0.68˝ – so it is no surprise that the Swissporarena is technically and acoustically up-to date and fulfills the stadium standard A +.
