Berghain has a Funktion-One sound system on its main dance floor which, when it was installed in 2004, was one of the company's largest club installs. At its launch, the sound system comprised four Funktion-One Dance Stacks (consisting of a DS210, a DS215 and three F218), a Double Infrahorn (consisting of two Infrabass, one Doublehorn Extension) and two Resolution 2 for monitoring. The Panorama Bar was upgraded in 2007 with a four-point line-array system with an additional six subwoofers from Studt Akustik.
