Philadelphia-based One Source Productions provided the sound for the Tipper & Friends gathering at The Gorge Amphitheatre in Washington State over Independence Day weekend. The event brought together thousands of fans for a multi-day celebration of music at one of the United States’ most iconic outdoor venues.

Known for its dramatic elevation, sweeping vistas and unpredictable winds, The Gorge challenges even the most experienced production teams. To meet those demands, One Source deployed a system comprising 24 Funktion-One Vero enclosures, 34 Funktion-One subs and the rental company’s full Evo 7 inventory.

Preparations began in Funktion-One’s Projection software, which enabled the team to model the audience area and refine the system design before arriving onsite. Correct placement was critical: the Vero arrays were flown 24 metres apart to achieve wide horizontal coverage and a strong stereo image and configured to deliver consistent, high-fidelity sound from the front of the bowl to the back. The main system was supplemented by ground-stacked Evo 7 in-fills and flown out-fills.

Low frequencies - a vital part of Tipper’s sound - were delivered through a combination of F124 and F221 subs. “The F124s provide incredible low-end extension, while the F221s add speed and punch,” said One Source’s Joe Adkins.

The results spoke for themselves. Tipper’s team commended the system’s responsiveness, while FOH engineers noted its ability to maintain clarity and headroom even at peak levels. Audience members frequently remarked on the immersive quality of the sound, regardless of their position within the vast venue.

A defining moment came during Tipper’s final sunrise set: an hour of ambient music performed as the sun rose over the stage. “Every detail translated with remarkable clarity,” said Adkins.

For One Source Productions, it was the perfect testament to their approach - that careful design and precise execution of Funktion-One systems elevates live sound from reinforcement to unforgettable shared experiences.
