A subwoofer also called a sub, is a loudspeaker often used to reproduce sounds which are of low audio frequencies as compared to the woofer. The low audio frequencies called bass or sub-bass are lower than the frequencies produced by a woofer.
The frequency range of a subwoofer is between 20 to 200 Hz for basic consumer products, less than 100 Hz for professional sounds used by artists and below 80Hz in THX approved audio systems which are normally used in professional theatres or cinema sound systems.
Purpose of Subwoofer
A simple home theater system consist of soundbars or speakers, AV receiver and subwoofer. Sometimes they are also used in surround sound setups, or for a surround sound system for your own PC. Subwoofers are not used alone as their main purpose is to amplify the low-frequency range of loudspeakers that mostly cover the higher frequency noises.
Technically speaking, the word "subwoofer" refers to the speaker driver. But in layman terms, the word often refers to the subwoofer driver mounted in a cabinet (a speaker enclosure) with an amplifier. The first subwoofer was made in the 1960s to enhance the bass in home stereo systems.
As both the woofer and subwoofer are used to produce low-pitched audio frequencies, the subwoofer produces the frequency band that you tend to feel which is up to 80 Hz and is not audible to the human ear. You feel this sound more than you hear it. Hence subwoofers are widely used these days to enhance the audio quality of the low pitched frequencies.
Types of Subwoofers
Subwoofers form a key element in almost any stereo system and hence their role is very crucial in audio systems. Subwoofers have many sizes, types and models. There are mainly two types of subwoofers:
- Passive subwoofers.
- Active subwoofers.
Passive subwoofers have a driver, enclosure and an external amplifier. While active subwoofers have a built-in amplifier. They were popular in the 1970s by the introduction of Sensurround sound in movies like Earthquake which produced a very loud low-frequency sound.
Importance of subwoofers
A lot of people think that two speakers, a left and a right stereo speaker are not enough for high-end home or mini-theatre audio systems. In-home music or theatre audio system sub-woofers play a crucial role in enhancing LFE (Low-frequency effects).
