Fred Roy Cizek (January 29, 1943 – April 12, 1993) was an American inventor, hi-fi designer, and manufacturer.^[1]

As the founder of CIZEK Audio System in Andover, Massachusetts, he became fairly well known in the audiophile world, especially in Italy, during the late 1970s for his company's high-quality speakers. Before starting his own business, Cizek worked for historical hi-fi manufacturers, such as Acoustic Research, JBL, and Altec Lansing. Blind since the age of three, he developed a special sensitivity for music reproduction and patented a special crossover to ensure a flat impedance curve to his speakers.
