40 Years of Pro Audio

My brand, 4-Acoustic, has been a household name in the industry for over 20 years. The company's history dates back 40 years, to my school days. Some friends of mine had formed a band and needed technical equipment for their performances, as well as someone to operate it. Due to my keen interest in electronics, I built the first amplifiers, electronic crossovers and speaker cabinets myself. In order to acquire the necessary knowledge, I studied a wide range of books and magazines on stage technology and electronics. After finishing school, this passion led first to an apprenticeship and a degree in electronics, and then to the decision to start my own business. As technical director, I now focus almost exclusively on product development. My brand, 4-Acoustic, distributes products worldwide that have already been used at events with over 100,000 attendees.
