Who fancies a 40,000-watt drivable tank with 13 speakers?

Nik Nowak's Panzer is no ordinary tank: its 13 huge speakers can be raised hydraulically for an ear-splitting sound display. It's a massive, 40,000-watt mobile sound system -- but it doesn't play club music. "People see the tank and expect techno," says Nowak, a 30-year-old sound artist. "But what they get is a pretty rough, primal soundscape. It's like an abstract poem, but more violent."

Nowak composes the music himself, using sub-bass frequencies that -- at 25hz -- are bordering on the fringes of human hearing, particularly for adults. His aim is to recreate the intense, physical reverberations one experiences inside a club, if not the tunes themselves. "I'm someone who went clubbing often," he explains, "and those low frequencies affect your body in a very extreme way. The kick-bass -- it really feels like your ass is being hit."

Berlin-based Nowak says he first became intrigued by sub-frequencies aged 14, when a gun went off beside his right ear. The hearing in that ear was damaged, and ever since he has found it irritating to listen to any high-pitched noise. "But when I'm in the studio, I'm working with bass frequencies that have a clear separation from higher sounds -- and so I don't get that irritation. So that's why I'm interested."

Nowak has performed with the Panzer in his art studio, a gallery, an outdoor music festival and even a TEDx conference in Berlin. He likes the idea that he has transported these violent sounds from their usual club context and into external society. "A club is like a temporary anarchistic zone," he says. "Through extreme acoustics, a club changes the way you perceive things. And to build this tank was to bring that experience into the world outside."
