The history of German Rainbow Audio began in 1984 when Paul Jelko, an electroacoustics expert, decided to create a high-quality automotive audio system in response to the poor quality of car audio systems available at that time. Paul Jelko and his team of mechanical and electronic engineers started out by researching and testing various materials to find the best combination for use in speakers.

        The Rainbow car audio brand was officially launched ，After years of research, they discovered that a combination of different materials, including paper, metal, plastic, and rubber, would provide the best sound quality. They then designed a speaker using these materials and patented the technology.  and quickly became famous in Europe.
