 interesting reading..

The very first subwoofer was developed during the 1960s by Ken Kreisel, the former president of the Miller & Kreisel Sound Corporation in Los Angeles. When Kreisel's business partner, Jonas Miller, who owned a high-end audio store in Los Angeles, told Kreisel that some purchasers of the store's high-end electrostatic speakers had complained about a lack of bass response in the electrostatics, Kreisel designed a powered woofer that would reproduce only those frequencies that were too low for the electrostatic speakers to convey.[6] Infinity's full range electrostatic speaker system that was developed during the 1960s also used a woofer to cover the lower frequency range that its electrostatic arrays did not handle adequately.

The first use of a subwoofer in a recording session was in 1973 for mixing the Steely Dan album Pretzel Logic when recording engineer Roger Nichols arranged for Kreisel to bring a prototype of his subwoofer to Village Recorders.[7] Further design modifications were made by Kreisel over the next ten years, and in the 1970s and 1980s by engineer John P. D'Arcy; record producer Daniel Levitin served as a consultant and "golden ears" for the design of the crossover network (used to partition the frequency spectrum so that the subwoofer would not attempt to reproduce frequencies too high for its effective range, and so that the main speakers would not need to handle frequencies too low for their effective range).

Subwoofers received a great deal of publicity in 1974 with the movie Earthquake which was released in Sensurround. Initially installed in 17 U.S. theaters, the Sensurround system used large subwoofers which were driven by racks of 500 watt amplifiers which were triggered by control tones printed on one of the audio tracks on the film. Four of the subwoofers were positioned in front of the audience under (or behind) the film screen and two more were placed together at the rear of the audience on a platform. Powerful noise energy in the range of 17 Hz to 120 Hz was generated at the level of 110–120 decibels of sound pressure level, abbreviated dB(SPL). The new low frequency entertainment method helped the film become a box office success. More Sensurround systems were assembled and installed. By 1976 there were almost 300 Sensurround systems leapfrogging through select theaters. Other films to use the effect include the WW II naval battle epic Midway in 1976 and Rollercoaster in 1977.[8]

For owners of 33 rpm LPs and 45 singles, loud and deep bass was limited by the ability of the phonograph record stylus to track the groove.[5] Some hi-fi aficionados solved the problem by using reel-to-reel tape players which were capable of delivering accurate, naturally deep bass from acoustic sources, or synthetic bass not found in nature. With the popular introduction of the compact cassette and the CD, it became possible to add more low frequency content to recordings, and satisfy a larger number of consumers.[9] Home subwoofers grew in popularity, as they were easy to add to existing multimedia speaker setups and they were easy to position or hide.[10]

That was interesting. However the best home system by a very long shot was on Turntable. The really high end models had great isoltaion.

If your talking about subwoofers then Cerwin-Vega! definitely deserves recognition as being a innovative pioneer in audio. They started in 1954 & the CV Strokers were used in the 1974 movie Earthquake. Also, Cerwin-Vega! participated in Sensurround technology.

BTW.. another breakthrough product, the world's first solid state amplifier was released in 1957 by Cerwin-Vega!

Meh, it's goin. No longer have a system in any vehicle. Got an 09 Titan and a 2011 Jetta TDI and everything is so integrated I refuse to mess with it. I see this forum still has retardedly slow traffic on it. Go figure. How's things been with you Fred?
