The loudspeaker turns 110 – An idea that changed the world
Ole Witthøft
The year is 1915. Two men – Danish engineer Peter Laurits Jensen and American Edwin Pridham – stand in a California workshop with a dream that seems almost impossible: to make the human voice stronger than ever before. It’s not just an invention – it’s
a mission to bring the power of sound to the masses.
On December 10, 1915, they present their invention: the first practical electrodynamic loudspeaker, called Magnavox – Latin for “great voice.” The technology is based on a coil moving a diaphragm using electromagnetism. This simple principle would become the foundation for all modern loudspeakers.
The invention quickly becomes a sensation. For the first time, sound can be amplified for an entire crowd. Jensen, born on the Danish island of Falster and a former collaborator of Valdemar Poulsen, left a Danish fingerprint on a technology that would soon change everything.
On September 19, 1919, the loudspeaker truly becomes world-famous. At City Stadium in California, U.S. President Woodrow Wilson stands before a crowd of 50,000 people.
Wilson speaks into two large horns, which channel his voice to microphones connected to a Magnavox loudspeaker system. For the first time in history, a president can address tens of thousands – and everyone hears every word. It’s not just a technical achievement; it’s a revolution in public communication. From that day, sound becomes a political force.
It’s almost unbelievable: only about 100 people in the world are older than the loudspeaker. For the rest of humanity, it has been a faithful companion from birth. From the first tones of early radio to today’s advanced surround systems, the loudspeaker has been the gateway to music, news, entertainment, and community.
Today, the loudspeaker is not just technology; it’s part of our life rhythm. It wakes us in the morning, entertains us on the go, and creates atmosphere at home. It’s with us in almost every moment – a silent witness to human history and an active center of our culture.
And there’s something universal about the magic of sound: everyone has a favorite song! We love different bands and genres, and our tastes change throughout life – from childhood tunes to teenage soundtracks and the melodies that follow us into adulthood. The loudspeaker delivers these experiences, a faithful messenger of emotions, memories, and dreams.
Silverback – The future of music systemsThe loudspeaker’s journey doesn’t stop here. System Audio has taken the next step with its Silverback music systems. These are not just loudspeakers – they are a modernization of the entire music system. Using advanced digital technology, they improve sound quality in ways previously impossible. They use fewer resources and materials, and they are upgradeable – a technological revolution that means users don’t have to throw them away to get the latest features.
The Silverback family proves that the loudspeaker’s ability to bring people together is far from outdated. On the contrary: it evolves, becomes smarter and more sustainable – and continues to be the heart of our musical experiences.

Although Jensen never patented his invention, his work laid the foundation for an industry that today generates billions and shapes our daily lives. From the early days of radio to modern Hi-Fi, streaming, and intelligent music systems – it all began with a Danish engineer, an American partner, and an idea stronger than silence.
Paradoxically, silence has become a scarce commodity. We live in a world where sound is everywhere – from traffic noise to constant music streaming and notifications. The loudspeaker, once a symbol of progress, is now part of a noisy reality. More than ever, we need to choose carefully how we use our ears and our time for high-quality experiences. Sound is not just background – it shapes our thoughts, feelings, and understanding of the world.
As the famous composer Claude Debussy once said: “Music is the silence between the notes.”
A reminder that even in a world filled with sound, silence – and awareness of what we listen to – is an art in itself.
Denmark’s audio and acoustics industry is one of the country’s most dynamic tech sectors. It includes about 1,100 companies and employs around 62,000 people, making audio technology one of Denmark’s strongest tech areas.
Economically, the sector is impressive: annual revenue of approx. Euro 11,4 billion and exports worth over Euro 9,1 billion, about 4% of Denmark’s total exports. The industry is also among the most innovative, with high patent activity and internationally recognized research.
About 90% of companies operate in four main areas:
Denmark not only has a proud audio history – but also a present and future where audio technology is a global strength.
