Acoustic Research, Inc. started manufacturing audio equipment in Cambridge, Massachusetts, in the early 1970s. The company was founded by Edgar Villchur, a pioneering audio-electronics teacher, researcher, and inventor. The company’s first speaker was the $185 model AR-1, which used the principle of acoustic suspension to deliver accurate audio reproduction. The company grew over the years and in 1989 it was bought by Jensen Electronics and later Recoton Audio Corporation.
