The changing sound of festival speaker set ups by TFS

The changing sounds of festivals – how speakers have adapted throughout the years

With festivals returning this year and Glastonbury set to bring in a 210,000 strong crowd, audio foam experts, Technical Foam Services (TFS), have looked back through the decades at the evolution of speakers and landmark festival moments.

Through the decades, audio foam has played an important role in speaker development with the introduction of speaker front foam in the 70s, designed to keep the speakers free from dust and other small particles.

TFS presents an eye-catching infographic timeline, mapping out important audio advancements. Starting with the muffled sounds of the 60s all the way to record-breaking music in 2014, and the return of Glastonbury in 2022.
