What's a subwoofer?

These speakers are specifically designed to handle extremely low bass such as that rippling effect of a thunderstorn with accurate power. Also handling normal bass frequencies of 40hz plus. Typical home systems cannot touch anything below 40hz even if you have bass. But good subwoofers can expand your audio experience dramatically. It's the big oblong box that sits on the floor that all your speakers are supposed to be hooked to. It carries the bass notes also. The Subwoofer plugs into a surge protector, along with all the other stuff with plugs. In the world of multichannel sound systems that dominates the manner in which people watch movies at home these days, you will see designations like 5.1 and 7.1. The number before the decimal point is the number of speakers you have around your listening room that deliver music, voices and sound effects to give you the perception that you are in the middle of the action that is on screen. Most of the speaker systems used today have what is known as satellite speakers for placement around the listening room. These speakers tend to be small and generally only reproduce mid-range and higher frequency sounds. In order to get the booming bass that rattles your bones when the action calls for it, you cannot rely on those little satellite speakers. You need a subwoofer, which is represented by the number 1 after the decimal point (5.1, 7.1) Since the deep bass sound waves do not need to come from each speaker, but only to be present in the room when appropriate, thus sound engineers have come up with the subwoofer. It is a dedicated bass speaker that only reproduces the low frequency sounds necessary for HT sound track.
