The Bose 901 Direct/Reflecting speaker system, a high-end piece of audio equipment, possesses several features. Introduced in 1968, each of the two active matrix enclosures houses nine individual 4.5-inch speakers. A separate active equalizer provides the speakers with a balanced tonal output in nearly any enclosed environment, which allows for a stereo effect regardless of where the listener is located in the room. In six iterations over 42 years, the Bose 901s have added more than 350 improvements and modifications, yet maintain the same overall basic design, components and appearance. Writer Bio
