The Foundation
of our concrete audio
speaker project

The trade name LAUTBRECHER is an allegory to a friendship that has been in existence for over two decades. It has grown and solidified as fully cured concrete. We got to know each other as kids, growing up in a small town near Mönchengladbach (Germany). One day we watched the James Bond movie “You only live twice” and we were fascinated by Blofeld’s space station, which was built inside a volcano. Full of enthusiasm we decided to recreate that volcano space station. At the time, we knew little about water ratios and the principles of reinforcement – the result was a solid 20kg heavy lump of plaster.

Some 20 years later, we are an engineer and a graphic designer sharing a flat in Düsseldorf. One evening over a beer in November 2016 we decided again to build something, this time, a concrete audio speaker. Over the following year we researched and built many prototypes until we reached a small series of minimalistic concrete speakers and LAUTBRECHER was born. The name translates to something like “loud crusher” and is similar to the German word for loudspeaker.


“As a youngster I had a job as a DJ and used my own setup on gigs. From time to time parts broke and had to be replaced. I did the repair work myself and got to know the elements of speaker building. I never lost the joy for music and have built many different sets of speakers over the years. I studied Materials Science, which really helps when it comes to working on new concrete formulas.”

“Back in the day, when we were practicing with our band I was already more into the idea of designing an album cover than making music. After the band split up, I focused on my graphical talent and studied communicational design. At LAUTBRECHER I can embed all my passion for product and corporate designs.”
