During the late 1980’s, our “Audio Pro” cassettes became the recognized standard of excellence in the cassette duplication industry. Steadily increasing sales made additional production equipment a necessity. In January, 1989, National Audio moved into a 28,000 square foot facility. In May, 1998, National Audio again expanded into a 135,000 square foot factory.
By early 2005, National Audio observed that most of the major cassette duplicators in this country were investing heavily in CD replication lines and reducing cassette duplication as they devoted space and personnel to CD lines.
Recognizing the on-going demand for audio cassettes for teaching materials, religious programs, high quality music, and books on tape, National Audio expanded its duplication services to fill the needs of the industry. During 2005 and early 2006, we purchased the equipment of several of the USA’s largest duplicators, signed confidentiality agreements with and began production for many more, and increased our customer base.
