Well to start with there are subwoofers popularly used in automotive applications and subwoofers for home entertainment systems. Beginning as a local trend by enthusiasts of enhancing a simple car stereo system with larger speakers for that deep bass sound, it has transformed into a mainstream specialized custom speaker industry.You will find that it has become rather popular to build subwoofer systems by encasing them in enclosures so they look and sound better, as well as fit nicely in vehicles. So today you will find many manufacturers producing mainly two types of subwoofers. Sizes will vary from 8 to 21 inches in diameter, producing sound below the 100hz range. In either case home or auto there are two types of subwoofers, passive and powered. The difference being passive speakers rely on power from the amplifying unit it is connected to as seen in car stereo systems. Whereas a powered subwoofer will have an amplifying unit contained within the speaker enclosure which is then connected to a main receiver, such as you would find for home entertainment systems.
