How Coaxial Speakers Tried to Reproduce Music From a Single Point

What if a loudspeaker could reproduce every note of music from a single point in space? In 1943, Altec Lansing introduced a revolutionary speaker design that promised to change how Americans experienced recorded sound: the coaxial loudspeaker. Instead of placing the woofer and tweeter in separate positions, coaxial speakers combined them along a shared axis, allowing bass and treble to appear to originate from the same location. This documentary explores the fascinating rise, decline, and survival of coaxial speaker technology, beginning with the legendary Altec Lansing 601 Duplex and the iconic Altec 604. Discover how these remarkable loudspeakers became trusted studio monitors in American recording studios throughout the 1950s, 1960s, and 1970s. We'll explore the pioneering Tannoy Dual Concentric design, Jensen coaxial and triaxial speakers, and the competition between Altec Lansing and JBL that helped transform professional audio. Learn why coaxial speakers eventually lost ground to conventional multi-driver systems, how engineers uncovered their distortion problems, and why the UREI 813 brought the single-point concept back into recording studios. The story continues with KEF Uni-Q technology, modern Genelec studio monitors, and Great Plains Audio, where descendants of the original Altec Duplex are still manufactured. From Hollywood recording studios to American living rooms, discover the forgotten history of one of audio engineering's most enduring ideas.
