Roy Cizek

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.

Cizek became blind as a child following a severe burn, which also caused chronic leg ulcers that has persisted throughout his life and never adequately healed.

According to the testimony of Ron Nadeau, a close friend who knew him at Indiana University in Bloomington, Roy was a man of great generosity, with fine skills in woodwork.

[2] In the 1970s, he moved to Cambridge, Massachusetts, with his wife Mary Francis Ramsey and their sons Fred, Carl, and Mitchell.

The speaker introduced the concept of flat impedance module, with only one peak at the resonance frequency achieved by a particular crossover.

The company's new president was a poor organizer, preferring to personally store all the addresses and contacts of suppliers and customers.

After the death of Feinstein, 30% of the company was taken over by Giancarlo Bonetti, an Italian importer of Cizek's brand in the 1970s and 1980s.
