Small speakers which are typically part of a small system will usually reproduce frequencies as low as 40 HZ particularly when the decibels rise above 100. A cone subwoofer will reproduce the bass tones from about 20 HZ down to 200 HZ, the point where the sound is as much vibration as tone.

The first known occurrence in a recording was the use of the subwoofer in “Pretzel” the Steely Dan album released after 1970 when the speakers were invented. The sound is actually produced by the drivers, which can range from 8″ up to as large as 34″. Typically drivers found in movie theaters, concerts, radio stations and live records in the 15 to 18 inch range. Part of the excitement of a live concert is the intense vibrations which emit from the enormous subwoofers.

A auto stereo system which comes from the factory usually does not include car audio subwoofers, aficionados of the hottest systems find they need to add aftermarket car stereo subwoofers.
