Wharfedale Pro XLA and WLA systems used under extreme alpine conditions at Lauberhorn

This year’s Lauberhorn winter event in Switzerland featured a Wharfedale Pro sound system across key race and hospitality zones, with XLA and WLA series line arrays selected to deliver announcements and music coverage in one of Europe’s most demanding outdoor environments.

The system was supplied and deployed by Stagepro Technical Solutions S.R.L of Studen, Switzerland, working together with Swiss distributor Sacher Music. High altitude, sub-zero temperatures and wind exposure defined the brief. With operating conditions between -15°C and -20°C and wind risk planning up to 150 kph, the audio design prioritised intelligibility, stability and consistent coverage across multiple audience areas.

On the main slope, Wharfedale Pro XLA series arrays formed the core PA system, projecting race commentary and programme audio across exposed open areas. The configuration was designed to maintain vocal clarity and tonal balance despite changing weather and wide listener distribution. In the lower arena, pairs of WLA-112 clusters covered around 1,500 spectators, providing focused coverage for announcements and music while keeping levels controlled and even across the audience zone.

The VIP hospitality tent required a different approach. Here, Stagepro deployed a flown combination of XLA and WLA-112 elements around the main screen structure to achieve smooth, even coverage within the enclosed space. This allowed speech to remain highly intelligible while music added energy and atmosphere without becoming intrusive or tiring for guests.

Amplification across the site was handled by Wharfedale Pro DP-2200N and DP-4100N amplifiers, offering Dante control and monitoring under continuous load. System transport and rigging logistics were also challenging, with subwoofers being removed from the mountain by helicopter after the event build-down.
