In one of my Ask Paul video questions, I was asked how far back subwoofers go in 2-channel audio. The community member had only become aware of subs as they related to home theater.
Of course, many readers of Paul’s Post know subs date back much further than home theater.
From Wikipedia: In September 1964, Raymon Dones received the first patent for a subwoofer specifically designed to augment the low-frequency range of modern stereo systems (US patent 3150739). Able to reproduce distortion-free low frequencies down to 15 Hz, a specific objective of Dones’s invention was to provide portable sound enclosures capable of high fidelity reproduction of low-frequency sound waves without giving an audible indication of the direction from which they emanated. Dones’s loudspeaker was marketed in the US under the trade name “The Octavium” from the early 1960s to the mid-1970s. The Octavium was utilized by several recording artists of that era, most notably the Grateful Dead.
Two years later, in 1966, my former partner in Genesis Technologies and the co-founder of Infinity, Arnie Nudell, along with his airline pilot friend, Carry Christie, launched the second and perhaps most important subwoofer of its time, the Infinity Servo woofer, based on an 18″ Cerwin Vega driver.
My experience with a subwoofer began a few years later when I was first introduced to a true high-end audio system. There, in the living room of local audiophile Norm Little, was serial numbers 1 and 2 of aerospace engineer Eugene J. “Gene” Czerwinski’s creation, a pair of 18″ Cerwin-Vega subwoofers capable of producing 130 dB at 30 Hz, an astonishing level during its time (or any time).
I suppose I have never gotten over the experience of hearing for the first time, all there is in the recordings, including subsonics.
Until you hear it all, you’re not going to know what true high-end is.
