Interaudio Speakers Model 4000 loudspeakers. Bose. Classic Vintage.
In the 1940s, Amar Bose, an American teenager of Bengali descent, repaired broken radios in the basement to support his family after his father’s import company collapsed during World War II. In 1953, after receiving the title of electrical engineer at MIT, he joined the group of employees of the famous research laboratory of the electronics department. In 1956, Bose obtained a doctoral degree, and in 1964 he founded Bose Corporation. Although the first high quality product launched to the retail market was a sales failure due to poor marketing, the company never made the same mistake again.
In 1968, the effort put into explaining the new technology and in-store presentations made the 901 speaker commercially successful, and 4 years later Bose began selling its products outside the US and created a department of specialized products targeted at professional musicians. In 1975, due to high quality and affordable price, the Bose 301 Direct / Reflecting speaker became a sales hit. In 1987, Dr. Bose (along with Dr. William R. Short) received the Inventor of the Year Award from the Intellectual Property Owners Education Foundation, and in 2008 an honorary place at the National Inventor Museum in Akron for achievements in the field of sound and the prestigious Red Dot Award for the best designer team in the world. Despite the death of Dr. Amar Bose (aged 83) in 2013, the company is still known and respected around the world as an audio expert.
Interaudio Speakers is a beautiful, classic Bose series from the early 70s, often confused by similar names with the later series Interaudio SA and Interaudio XL.
According to the original instructions from 1972, Interaudio Speakers were created thanks to the use of advanced technologies such as the Acousticouple design and the Syncom computer used to test the speakers, which enabled the delivery of a totally new level of sound quality.
