Eng Multon (August 9, 2008): The Cizek Model One was the first HIFI product of CIZEK Audio System, a two-way bookshelf loudspeaker system which gave a certain notoriety to Roy Cizek, founder of the company. This product was important because it was the first loudspeaker system which, due to its particular crossover, showed a flat impedance curve (except for the resonance peak) with a consequent easier work for the amplifier and linear frequency response.
Another peculiarity of the Cizek One was a switch that permitted selection of the Q factor of the bass frequencies; thus, the listener could choose a more or less controlled bass depending on the kind of music or ambient acoustic characteristics. The Cizek Model One became the most successful product of the Company since 1976, first year of production.
Eng Multon (August 9, 2008): Roy R. Cizek (Italian: Roy Cizek, born January 29, 1943) was an American inventor who developed high end audio loudspeakers throughout the late 1960s and up to the 1990s. Despite being blind, he produced a line of speakers under his own name that are even today considered groundbreaking in their high definition and clarity
Roy was not blind from birth. He had normal vision as a youngster until the age of 2 or 3 years, but suffered eye damage when his cowboy suit caught fire. His worst affliction, however, was his legs, which were ulcerated from the fire and never healed well. They had to be soaked every day. Friends reported that Roy was his worst enemy; drinking several cases of Coke, weekly which caused him to become a type 2 diabetic. Cizek's closest friend and constant side-kick was Ron Whaley, who was also legally blind though he could see to a limited degree.
Raised in Bloomington, IN, Roy Cizek was in the band at Indiana University, and is listed as an alumni member of the Alpha Zeta Chapter of the Kappa Kappa Psi Fraternity, a National Honorary Fraternity for College band members, operating exclusively in the field of the college and university bands. Cizek's father, Fred Cizek, was an up and coming trumpet player who played in big bands back in the 1940s.
Cizek and his wife Fran and son Carl moved to Cambridge, Massachusetts in the 1970s, working in the HiFi industry as a consultant at companies like Acoustic Research. Between 1978 and 1980, he worked as an engineer at Audio Dynamics in Connecticut. Later in his career, he moved away from New England to work for Altec Lansing.
Fellow workers considered Roy Cizek a spectacular engineer, acoustician, music buff and intriguing fellow to know. Some writers on the internet refer to Roy Cizek as "The Golden Ears of Altec Lansing." Roy could tell more about a part by fondling it for a minute than most people could tell by measuring it. His ability to visualize internally, spatially and conceptually and turn that vision into a product was a marvel to witness. His design process was rigorous and he was a bit of a perfectionist. He knew quite precisely what he wanted and knew how to hold out to get it. He would drive those driver manufacturers nuts in getting just the exact right spiders, cones, pole pieces, coils and so on to meet "his spec." While working as a consultant at Acoustic Research, Cizek was largely ignored by the engineers and was looked upon as a nuisance. Roy knew nothing about how companies were run and the internal politics that were prevalent there, so Cizek was considered a threat to many engineers and did not realize that he had to make them feel as if they contributed to his efforts rather than make them look bad. He showed how he could extend the range (low-end response) by 6-7 Hz with their speakers without sacrificing anything or increasing costs. Fellow workers lauded Cizek's talent at producing "good quality sound without making the speakers too high priced."
In the late 1970s, Roy Cizek founded his own company, Cizek Audio, which was based in Andover, MA.
In 1976 Roy Cizek produced his most successful product: "The Cizek Model One." A later model, the KA-1, was produced in KOA wood. Many sound engineers considered The Cizek Model One one of the best 2-way speakers ever produced: they had a special cross-over with a flat impedance which gave fantastic sound to these system.
Cizek's skills were not limited by his lack of vision and he often said he would much rather have healthy legs before sight. Cizek married three times, including a woman from Haverhill, MA, who moved away with him from New England when he got a job working for Altec Lansing. Roy Cizek's last official residence was in Torrance, California, where he died on April 12, 1993. A scholarship was created in Roy's name at the Indiana School for the Blind by his two stepdaughters in 2002.
Michelle Day (September 30, 2009): Hi, my name is Michelle and I was Roy Cizek's stepdaughter for all of my high school years until he moved away to OK with my mother Dorothy then to CA where they unfortuneately divorced. During the years I knew Roy, and his best friend Ron I had the pleasure of getting to know him on many different levels. He was an amazing man and am happy and proud to have known him. He taught me to always shoot for my dreams. I miss him and will always remember him. Sadly, my mother, his second renently died in april of 2008. If I could be of any help in assitting with any information about Roy, please feel free to contact me. Thank You, Michelle Day
