In the early 1960s, AR conducted a series of over 75 live vs.recorded demonstrations throughout the United States in which the sound of a live string quartet was alternated with echo-free recorded music played through a pair of AR-3s.For nearly ten years after its introduction, the AR-3 was widely regarded as the most accurate loudspeaker available at any cost, and was used in countless professional installations, recording studios, and concert halls.
Acoustic Research was a Cambridge, Massachusetts-based company that manufactured high-end audio equipment. Acoustic Research was well known for the AR-3 series of speaker systems, which used the 12-inch (305 mm) acoustic suspension woofer of the AR-1 with newly designed dome mid-range speaker and high-frequency drivers, which were the first of their kind.
Even after the "improved" version of the AR-3, the newer AR-3a model was introduced to the market in the mid 60ies, Acoustic Research continued to manufacture the original AR-3, by then over 10 years old, until the 1970ies.
