Renkus-Heinz was founded on April 1, 1979 by Harro K. Heinz and Algis Renkus (1937–1997[7]).[1] Heinz had previously been awarded a patent in 1975 for his work on a "Comprehensive feedback elimination system employing notch filter"[8] that was performed while he was employed at Rauland Borg Corporation, the company he left to found Renkus-Heinz.[9] Algis Renkus was joined in the new enterprise by his father Jonas A. Renkus (b. 1912) who had worked at Altec under industry veteran John Kenneth Hilliard.
While at Renkus-Heinz, Jonas Renkus patented a new triple lamination construction method in 1980.[10] In 1981, the two Renkus men left Renkus-Heinz to assist Emilar, which was having trouble staying in business. Harro Heinz remained president of Renkus-Heinz.
While Jonas and Algis Renkus were at Emilar, they began using the patented triple lamination method which had been assigned to Renkus-Heinz. Heinz sued for damages but dropped the case during the hearing.[11]
In 1989 Harro's son Ralph D. Heinz joined Renkus-Heinz to work with Don B. Keele, Jr. and Gene Patronis and further his knowledge of electro-acoustics and horn loudspeaker design. Ralph Heinz eventually became senior vice-president of R&D[12] and patented a method of arraying loudspeakers for better phase coherency in 1994.[13] In 1996, he patented a multiple driver horn which was promoted as the "CoEntrant" transducer, covering both mid- and high-frequency bands in one horn.[14][15] In 2016, Ralph Heinz was named Chief Technical Officer.[16]
In 1999, Harro's daughter Monika Heinz Smetona joined Renkus-Heinz on the administrative team and was named chief operating officer in 2016.[17] She was then named chief financial officer in 2019.
