A loudspeaker or speaker is an electromechanical transducer which converts an electrical signal into sound. The term loudspeaker is used to refer to both the device itself, and a complete system consisting of one or more loudspeaker drivers (as the individual units are often called) in an enclosure. The loudspeaker is the most variable element in an audio system, and is responsible for marked audible differences between systems. Here are some of the various types:
| | Multi driver systems - Home loudspeaker systems are generally multi-driver systems. 'Multi driver' refers to any speaker system that contains two or more separate drive units, including woofers, midranges, tweeters, and sometimes horns or super tweeters. |
| | Woofers - A woofer is a loudspeaker capable of reproducing the bass frequencies. The frequency range varies widely according to design. Whilst some woofers can cover the audio band from the bass to 3 kHz, others only work up to 1 kHz or less. |
| | Mid-ranges - A mid-range loudspeaker, also known as a squawker is designed to cover the middle of the audio spectrum, typically from about 200 Hz to about 4-5 kHz. |
| | Tweeters - A tweeter is a loudspeaker capable of reproducing the higher end of the audio spectrum, usually from about 1 kHz to 20 or 35 kHz. |
| | Full-ranges - A full-range speaker is designed to have as wide a frequency response as possible. These often employ an additional cone called a whizzer to extend the high frequency response and broaden the high frequency directivity. |
| | Subwoofers - A subwoofer driver is a woofer optimized for the lowest range of the audio spectrum. Modern speaker systems often include a single speaker dedicated to reproducing the very lowest bass frequencies. This speaker (and its enclosure) is referred to as a subwoofer. A typical subwoofer only reproduces sounds below 120 Hz (although some subwoofers allow a choice of the cross-over frequency). |
