Snow White's Coffin

The end of hiding technology

Before the Braun SK 4, radios and phonographs hid. They came wrapped in wooden cabinets designed to look like furniture, their mechanical innards concealed behind grilles and doors. The technology was new; the aesthetics were old. A record player in 1950 wanted to pass as a sideboard.

Rams, working with Hans Gugelot, refused the disguise. The SK 4 was a white metal box with pale wood sides and a lid made of plexiglass. You could watch the record spin. You could see the tonearm move. The nickname came quickly: Schneewittchensarg — Snow White's Coffin. Something had died. The era of hiding technology behind Victorian furniture was over. What followed was a half-century of designers treating audio equipment as objects worthy of display. The SK 4 didn't start a movement so much as it gave permission.

Two approaches to material & form

Charles and Ray Eames had arrived at a similar conclusion a decade earlier. They spent the early 1940s experimenting with the Kazam! machine — heated plates and a bicycle pump pressing wood veneer into compound curves. In 1943, the U.S. Navy commissioned them to produce lightweight plywood leg splints, and by the time the war ended they had mastered three-dimensional wood forming at a level no one else could match.

The model 6D030, released in 1946, curved like a small sculpture — warm in a way plastic never is. It was organic where Braun would be geometric. Molded plywood absorbs and disperses vibration more effectively than plastic or metal. Form followed function followed material followed luck.

Rams codified what the Eameses had intuited. His ten principles of good design became the theoretical framework for Braun's audio products and eventually for an entire school of industrial design.

Good design is innovative, useful, and aesthetic. It makes a product understandable and unobtrusive. It is honest, long-lasting, thorough to the last detail, environmentally conscious. It is as little design as possible.

This corporate purity shaped Massimo Vignelli's graphic systems and, decades later, Jonathan Ive's work at Apple. The early iPods owed so much to Braun's portable radios that the resemblance became a design-school cliché.

Personality vs neutrality — Milan vs Frankfurt

Not everyone wanted their living room to feel like a laboratory. In Milan, Achille and Pier Giacomo Castiglioni were asking a different question: if audio equipment was going to be visible, why shouldn't it have personality? Their answer was the RR126 radiofonografo, designed in 1965 for Brionvega. It looked like a robot. The volume dials were eyes. The speakers were ears. Achille called it a "musical pet" — where Rams designed for neutrality, the Castiglionis designed for companionship. The RR126 was also modular and genuinely clever. It weighed over thirty kilograms. David Bowie owned one. Of course he did.

Harry Bertoia took the conversation somewhere else entirely. In the early 1960s he began building Sonambient sculptures — clusters of metal rods designed to produce sound when touched or stirred by the wind. He experimented with beryllium copper, silicon bronze, and monel and inconel, each alloy with its own voice. He converted an eighteenth-century stone barn in Bally, Pennsylvania, into a private concert hall and filled it with nearly a hundred of these sculptures. The barn still stands. When you walk among the rods and set them ringing, you are inside a single instrument that took decades to build.

The exhibition

This history is now the subject of Art of Noise, on view at the Cooper Hewitt, Smithsonian Design Museum in New York through August 16, 2026. Organized by SFMOMA and curated by Joseph Becker, the exhibition brings together over 800 objects — radios, phonographs, posters, album covers, and immersive sound installations including Devon Turnbull's handmade listening room.

From the Eames radios to Bertoia's tonal sculptures, the objects displayed share a single conviction: that the machines we use to hear music deserve to be seen. The plexiglass lid was a small choice. Everything followed.
