The story of PSI Audio started in 1975 when Alain Roux started producing his first speakers while studying at EPFL in Lausanne. Two years later Alain started making a profit selling his speakers and decided to found a company called Roux Electroacoustique. In 1988 the company became a Limited Company and was renamed Relec SA. At this time Alain also relocated the company in to a new purpose built facility in Yverdon-les-Bains. Over the years, Alain and his team developed a huge variety of speakers starting from the Hi-Fi industry, Public Address systems all the way to Professional Studio applications. Many speakers where also produced as OEM products under the brand names of respected international companies. Several of these products have gone on to win the industry’s most desirable awards. PSI Audio has developed to become a respected worldwide brand, producing the ultimate professional studio monitors.
