A separate Woofer Box dedicated to Reproducing the Low Bass Signals found in Music and Movie Soundtracks. Gives most Systems a Significant boost in Scale and Authority.
A speaker which can reproduce sound at the lowest end of the sound spectrum.
A speaker that is dedicated to reproducing the lowest octaves on a soundtrack. Powered subwoofers include their own amplification, while passive models must be driven by external amplification. Most powered subwoofers include crossover circuitry that blends the subwoofer's output with the main speakers. [Go to source
a loudspeaker that reproduces the very low sounds usually in the range of 20Hz to 1000 Hz.
Subwoofers are loudspeakers dedicated to reproduce just the very lowest of audible frequencies and are usually monaural. They are mostly self-amplified and feature different hook-up options like high-level and low-level in- and outputs. In low-level hook-up, the subwoofer is inserted between preamp and power amp and filters the bass portion out of the signal passed on to the main speakers. This is usually the preferred method for small bass-shy monitor-type loudspeakers or when high playback levels cause the main speakers to sound distressed in the bass. In high-level hook-up, the subwoofer, just as the main speakers, is connected to the power amplifier. This leaves the main speakers to run "full-range" without any bass filtering. In such augmentation mode, the subwoofer’s crossover is set to merely fill in bass below what the main speaker is capable of producing. High-level hook-up tends to be preferable for speakers that extend to 60Hz or lower as it avoids placing the subwoofer and main speaker crossovers in series.
A speaker or speaker/enclosure system designed to reproduce only bass frequencies. Generally used only below 80Hz.
A specific type of speaker dedicated to reproducing very low frequency sounds. Usually a big cabinet located on the floor; placing the cabinet on the floor mechanically couples the low-frequency vibrations to the floor, enhancing the effectiveness.
A speaker that's designed to reproduce very low frequencies (only), typically below 50Hz. Usually employs the use of very large cone drivers. The frequency range and size of the subwoofers is relative to the rest of the speaker system they are designed to accompany. If a main speaker has a frequency response down to only 80Hz, the subwoofer used may cover 50Hz to 80Hz. If the main system goes down to 50Hz, the subs may operate from 30Hz to 50Hz.
An additional bass speaker which produces a rich powerful bass sound with the lowest sound tones.
A loudspeaker that reproduces the powerful low (sub base) frequencies
A speaker designed specifically to reproduce low-frequency information, usually between the range of 20 to 120 Hz. Dolby Digital soundtracks provide a separate low-frequency effects (LFE) channel specifically for playback over subwoofers.
A large bass driver in its own cabinet that comes in two types: powered and passive. Passive subs draw power from an amplifier or receiver, while powered subs have their own amplifier.
A specific type of speaker dedicated to reproducing very very low frequency sound.
A speaker dedicated to producing powerful low frequency sounds - that's bass to you and me! DVDs with Dolby Digital 5.1 or DTS 5.1 soundtracks are encoded with a Low Frequency Effects channel especially for those trouser-flapping explosions, seismic spacecraft, rumbling thunderstorms, etc.

A speaker designed to reproduce the very lowest frequencies, or deepest bass, usually below 80 Hz. Subwoofers often include a built-in amplifier to provide the power needed to generate deep bass.
A speaker designed to reproduce bass (low frequencies). Bass is not very directional, so most home cinema systems only need one mono bass channel.
A speaker designed to specialize in low-frequency reproduction. A true subwoofer should be able to at least reach into the bottom octave (20-40Hz). Although any location will result in bass that appears to come from the satellite speakers, they usually sound best when placed near the front speakers.
Woofer large enough to produce frequencies from 20 or 30 Hz to 80 or 100 Hz, typically housed in its own enclosure.
A subwoofer is an individual speaker commonly found in home theater sound systems that processes bass sounds as low as 15 hertz.
A hefty speaker that delivers very low frequencies only
A woofer housed in a separate enclosure from other drivers to produce ultra low bass.
A speaker, usually with internal amplification, that produces only low frequency sounds, known as bass. See LFE.
A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz and as low as 15 hertz.
A speaker designed to reproduce low bass frequencies, usually those below about 80 Hz. Subwoofers are used for both music systems and home theater systems.
A separate loudspeaker unit that reproduces very low bass.
Used for the reproduction of low sound frequencies, typically from 20Hz to 200Hz. Whether in the car or at home, the subwoofer is critical for filling out the "low end" of the audible spectrum, as well as ground pounding bass.
An audio device dedicated to replicating the lowest, deepest sounds ascertainable by the human ear.
A low frequency speaker with a frequency response range of 25Hz to 120Hz. Used to produce deep, bass tones.
A speaker that reproduces very low frequencies.
An electronic or mechanical device that extends the deep-bass response of an audio system. The most common are add-on, large, conventional woofers, which must be careflilly aligned to work properly. Electronic-type "subwoofers" are actually equalizers that are dedicated to standard woofer systems and electrically boost the low-bass range to achieve smooth, flat low-bass response. Many add-on subwoofers incorporate electronic equalizers to flatten out the bottom of their ranges. See also Equalizer; Woofer.
A specialized loudspeaker that handles only bass frequencies (typically 200 Hz and below). The subwoofer is ideally suited to reproducing the "0.1" Low Frequency Effects channel of modern surround sound systems. Most subwoofers are also "active," meaning that they include their own power amplifier.
a loudspeaker designed to reproduce only bass frequencies.
A speaker designed to reproduce low-frequency bass signals, usually from 1200Hz down to or below 20Hz.
A large speaker in a heavy enclosure that reproduces the lower bass notes.
A speaker designed exclusively for low-frequency reproduction. A true subwoofer should be able to at least reach into the bottom octave (20-40Hz). There are many "subwoofers" on the market that would be more accurately termed "woofers".
A subwoofer is a (usually powered) speaker which produces very deep booming bass sounds. Subwoofers are responsible for reproducing the LFE track in a 5.1 Dolby Digital or DTS soundtrack. They are typically a cube shape with a large single woofer either pointing directly at the ground or directly at the listener. Usually, subwoofers are placed in the corner of the room. Ideally, a subwoofer should be placed where it is impossible to determine the direction of where the sound is coming from.
A large bass driver built into its own cabinet. Since the human brain cannot detect the point of origin of deep bass frequencies, a single sub-woofer can be placed almost anywhere to reproduce the lower end of sound. Subwoofers come in two types -- passive and powered. Powered subs have their own amplifiers, while passive subs use a system's main amplifier.
Special form of speaker used to reproduce only the lower portion of the audible frequency spectrum usually from 80 Hz down to or below 20 Hz.
A subwoofer is a speaker that produces very low sounds, at least some of which are too low to actually hear. Usually unnecessary for music, home theater has popularized them, because surround-sound movies, like Dolby-Digital DVD's, have special information called Low Frequency Effects or LFE. These are the sounds that make the floor shake during an earthquake or explosion. Since it can take quite a bit of energy to shake a floor, most LFE subwoofers are powered; they have their own built-in supplementary amplifier.
This is a separate speaker used to handle the bass of movie soundtracks, and can be used with the Low Frequency Effects channel in the new digital sound formats. These speakers can sometimes handle frequencies as low as 15hz.
A passive subwoofer is a powerful bass loudspeaker, which stands alone in a box, needing a power amplifier in the equipment to which it is connected. The more common active subwoofer incorporates its own mains-powered amplifier, and takes a signal feed at low ('line) level.
A special speaker that plays only low frequencies. A subwoofer gives a speaker system a BOOM BOOM. It can be placed anywhere on the ground, even under a couch, and still be effective.
A speaker that produces low-audio frequencies also known as bass.
A speaker driver designed to reproduce very low frequencies, usually those under about 100 Hz. Often larger than 6.5 inches in diameter. However, since this is a relative term, even a 15-inch driver in a two-way system is really a woofer, not a subwoofer.
A speaker, usually powered by its own amplifier, that handles the low frequency, or bass, sounds.
A very low frequency speaker with a frequency response anywhere from approximately 25Hz to as high as 120Hz. Depending on the application, either 40Hz or 80Hz is generally chosen as the crossover point.
Dedicated speaker for bass information in the low base range and low-frequency energy (LFE) production, which is recorded as a separate track
A speaker designed to reproduce extremely low frequencies (bass). Since bass is not very directional, most home theater systems only need one mono bass speaker.
A loudspeaker made specifically to reproduce the lowest of audio frequencies, approximately between 45 Hz and 125 Hz .Generally used only below 80Hz.
Extra low frequencies driver which can be used to augment both stereo and surround systems.
The loudspeaker used to reproduce the signal from the low-frequency effects (LFE) channel.
A type of speaker used to enhance bass response in an audio or home theatre system. It contains a woofer (or woofers) in an independent enclosure. Subwoofers are generally intended to cover the range below 200Hz and can extend down to 20Hz or below. They lend weight to the overall sound and presentation of a system by providing extended bass response and low-frequency impact which can be felt physically, but is inaudible to the human ear, especially on action movie soundtracks. Due to non-directional nature of this bass sound, a subwoofer can be positioned almost anywhere in a normal room.
A subwoofer is a type of loudspeaker dedicated to the reproduction of bass frequencies, typically from about 20 Hz to perhaps 200 Hz in cone speakers, and in the case of a rotary woofer, all the way down to below 1 Hz. It is difficult for small loudspeakers in typical enclosures to reproduce frequencies below about 40-50 Hz, especially at high output levels (say, above 100 dB) as their cones will move farther than any practical driver construction can provide for , and so it is often advantageous to use a loudspeaker specifically designed for handling low frequencies at high power levels.
