This page will contain additional articles about Subwoofer, as they become available.SubwooferWooden subwoofer.A subwoofer is a loudspeaker which reproduces bass frequencies from about 5 Hz to about 90 Hz. Frequencies 16 Hz or lower are more felt than heard. So-called subwoofers which reproduce frequencies from about 35 Hz to about 150 Hz are more properly described as bass modules than true subwoofers. It is difficult for small loudspeakers to reproduce frequencies below 40 Hz, especially above 100 dB, and so it is often advantageous to use a loudspeaker dedicated to this task. OverviewSubwoofers use drivers (woofer) with cones typically coming in 10" or 12" sizes, but can be as large as 34", and as small as 4". Diameter tends to be advantageous because low frequencies involve shifting a great deal of air; a recent trend has been for high excursion, i.e., how far the cone can linearly travel from its resting position; for example, some can move as much as 2.5" in or out, yielding an overall displacement of 5" (this is controlled movement range). Subwoofers are usually powered by a high power amplifier, and often an electronic crossover ensures that higher frequencies will not be directed to the subwoofer. The need to reproduce these frequencies has increased since older formats, such as vinyl records, have been displaced by digital formats, such as CD, and particularly 5.1 formats such as Dolby Digital, in which the ".1" channel is dedicated solely to the subwoofer. The .1 channel is usually dedicated to extended bass frequencies, for example, the low frequencies of a gunshot, string bass, or thunder. This track is often used aggressively by mixing artists. ApplicationsProfessional audioSubwoofers are found in professional applications such as live concerts, movie theatres, various other sound reinforcement applications (ranging from nightclubs to theme restaurants) and studios. Some of these applications require subwoofers designed for very high sound levels, such as the JBL 4645 – certified for THX movie theatres – which uses an 18" driver (woofer). Note that movie theatre speakers (situated behind a perforated screen) typically use 15" drivers (woofers), so the use here is only to reproduce the lowest frequencies at high sound pressure levels. Large concert sound systems always use subwoofers (referred to as "subs" by the engineers and crew). The bulk of the sound system is usually "flown" (suspended from the ceiling by chain hoists) and the subs are usually stacked on the stage or the ground in front of the stage to the left and right of the performance space. An unusual example of the use of sub-woofers came with the release of Earthquake in 1974 where they used a system called Sensurround to create a feeling of an earthquake. This was simply a set of large sub-woofers designed to create infra-bass (felt but not heard). Similar systems are used in theme park rides, such as "Days of Thunder," which uses sound to simulate a physical impact. Many times the subs are not part of the entire sound mix but are specifically fed just kick drum, bass guitar and other low-frequency content from a separate output on the main mixing console. Popular sub systems in use currently are made by companies such as EAW but usually the subs will be made by the manufacturer of the rest of the PA system such as L-Acoustics and their V-Dosc Line Array with its matching dual 18-inch sub cabinets. Similar popular PA systems are made by JBL, Electro-Voice, EAW and Meyer Sound. The 18-inch woofer driver is the primary majority device for pro audio applications. They are usually direct radiating in a ported enclosure built of 13-ply birch. For electronic music events with at least a thousand audience members there are often more than 20 double-18-inch cabinets on either side of the stage. 12-inch drivers in very large folded horns are also becoming popular now. One of the most powerful subs manufactured can play as low as 25 Hz and can cover thousands of feet and uses two 12-inch woofers on a 13-foot (4 m) long folded horn (the EAW bh822e or KF940). A now-discontinued but popular Electro-Voice subwoofer employs a "Manifold Technology" configuration to fit four 18-inch drivers into a relatively compact enclosure. Intended for applications such as night club installations and concert sound reinforcement this cabinet is still popular with PA system equipment rental companies. Another extreme pro audio device is the ServoDrive ContraBass, where the driver's cone is moved using a belt-drive coupled servo motor. A large horn-loaded version called the BassTech-7 can be found in venues such as theme park rides. Pro Audio subs have to be capable of very high output levels – after all, concert venues may seat 10,000s of individuals outdoors. On average, music applications generally require less capability than movie soundtracks in the very lowest octave, but modern popular music is changing this preconception and this is reflected in the design attention given to the subwoofer section of the PA system nowadays compared to a couple of decades ago. People who are accustomed to bass in home audio systems and car audio many times think that the subs in a concert PA system aren't putting out that much. Considering they operate outdoors and the average listener is hundreds or even thousands of feet away from the devices, they are impressive. Home audioIt should be noted that a subwoofer does not necessarily provide superior bass performance to large conventional loudspeakers; they are merely subwoofers because they ought to reproduce only the lowest frequencies. A conventional woofer may reproduce frequencies up to 200, 300, or in a two-way speaker a mid-woofer (paired with a tweeter) also handles midrange, up to 3,000 hertz or more. Rather, the intention may be to use small main ("satellite") speakers (of which there are 2 for stereo, and 5 or more for surround sound) and locate ("hide") the subwoofer elsewhere; to augment an existent speaker to relieve it of reproducing bass and gain output level and/or quality; or because high levels of low bass are required and using a dedicated amplifier and speaker provides the output level and quality required. Thus, subwoofers may be part of a package that includes satellite speakers, purchased separately, or built into the cabinet of a conventional loudspeaker. (e.g., some speakers include a subwoofer in the lower portion of the cabinet.) Physical separation of subwoofer and "satellite" speakers not only enables placement in an inconspicuous location, but since sub-bass frequencies are particularly sensitive to location (e.g., due to room resonance and 'modes'), the best position of the subwoofer may not be where the "satellite" speakers are located. (e.g., it has been suggested subwoofer(s) be placed in the corner of the room, far from large room openings, and closer to the listener.) This is possible since low bass frequencies have a long wavelength; hence there is little difference between the information reaching our left and right ears, and we are unable to easily locate their direction below 90 Hz. Harmonics at higher frequencies (from the satellites) can then be used, by the auditory system, to calculate the directional information. Note that only one subwoofer need be used, even when using 5 or more satellite speakers—e.g., for surround sound. All low frequency information is sent to the subwoofer. ("Bass management" or "Small" mode for the satellite speakers is common among equipment such as Dolby Digital surround processors/receivers.) The physically separate subwoofer/satellite arrangement has been popularised by lifestyle systems, such as those manufactured by Bose, and multimedia speakers, examples of which include the Klipsch ProMedia. Particularly among low cost systems, however, it may be little more than a marketing device: it's not likely that a small woofer in a compact cabinet will have better bass performance than good speakers; as mentioned, the term "subwoofer" is no guarantee of particular bass performance. Most multimedia "subwoofers" should probably have been called "woofers". They are too weak to play any real deep bass. Further, small satellites systems typically cross over the bass above 90 Hz, introducing the subwoofer "localization effect". On the other hand, high-end domestic subwoofers are manufactured by companies such as M&K, HSU, Velodyne, SVS, and REL. These can be purchased separately, to be added to an existent system or when considering a set of speakers; or as part of a high-end speaker package. All of these subwoofers tend to have in-built amplification. Car audioThe automobile is ideal for the "hidden" subwoofer approach due to space limitations of locations such as doors (ignoring the acoustic problems of a car interior). Typically, subwoofers are installed in the trunk. Curiously, some car stereo enthusiasts seem intent on producing ultra-high sound pressure levels in the confines of their vehicle's cabin. In international car stereo competitions, over 100 subwoofers driven by some 100,000 watts have been used to generate over 180 decibels. Naturally, these sound levels are not safe for humans. Such "SPL wars" have drawn much attention to subwoofers in general, but subjective competitions of sound quality ("SQ") has not gained similar popularity. Indeed, hearing loss is one concern, alongside space considerations and neighbour relations. Since much bass is felt, sub-bass can be augmented using tactile transducers. These have recently emerged as a device, called a tactile transducer by at least one brand, that attaches to furniture, such as one's seat, via which vibrations are transmitted to the body; they can be connected to an amplifier as per a normal loudspeaker. However, some feel that the vibrations are a little disembodied from the rest of the auditory experience. These devices typically don't provide as much vibration per dollar as simply placing a reasonably priced subwoofer against the back of the furniture, so at their current prices are most useful for not disturbing anyone than vibrating to audio. They can be placed on a large flat surface create a large, though poor, loudspeaker. Some waterproof models work underwater, or placed on the underside of a deck, to create sound. Non-round subwoofersWithin the last few years, the car audio field has seen a variety of subwoofers utilizing non-round shapes. Stillwater Designs, nicknamed Kicker, released a square subwoofer several years ago, the Solo-Baric series, and recently, the Solo X. Bazooka has introduced a triangular subwoofer. Xtant has introduced a hexagonal subwoofer. Other companies, such as Sony, have jumped on the bandwagon, producing non-round subwoofers of their own. There is no known auditory advantage to these shapes. However, they can be useful in creating unique 'looks' in a car audio system that is meant to be seen as much as heard, and to create brand distinction and recognition. The intent of a square subwoofer is to increase the surface area of the woofer's cone. In enclosures of the same size, it is possible to achieve more subwoofer cone surface area with a square design than a circular design. The increased surface area translates into moving more air and higher sound pressure levels. However, a triangular design decreases the surface area of the woofer cone relative to a circular or square design in an enclosure of the same size. The intent of the triangular design does not seem to be motivated by sound quality or intensity, but rather to encourage creativity in installation and provide flexibility for otherwise awkward positions. Sony claims that its pentagon shape reduces standing waves on the surface of the cone as well as improves the overall strength of the cone structure, reducing "cone flex". They further claim that Kicker's square design puts too much stress on the corners of the cones. These claims are scientifically disputed and unresolved as of yet.

These claims are scientifically disputed and unresolved as of yet. All albums are now also available for purchase and download as Windows Media, MP3, and/or lossless FLAC files from the Dave Matthews Band website. They further claim that Kicker's square design puts too much stress on the corners of the cones. Other benefits of the Warehouse Fan Association is members receive bonus companion CD's when they pre-order official Audio and Video releases. Sony claims that its pentagon shape reduces standing waves on the surface of the cone as well as improves the overall strength of the cone structure, reducing "cone flex". Their Warehouse Fan Association pioneered the internet-based ticket presales used by many artists today. The intent of the triangular design does not seem to be motivated by sound quality or intensity, but rather to encourage creativity in installation and provide flexibility for otherwise awkward positions. Though tickets may be purchased before the general public, this does not mean that Warehouse tickets will always be the best seats, and seat locations are not disclosed until roughly a month prior to the show date. However, a triangular design decreases the surface area of the woofer cone relative to a circular or square design in an enclosure of the same size. Another fan-friendly trend of Dave Matthews Band, in the tradition of The Grateful Dead and Phish, is that they allow their fans to purchase tickets to their performances before they go onsale to the general public. The increased surface area translates into moving more air and higher sound pressure levels. AntsMarching.org is currently a popular site for trading Dave Matthews Band tapes. In enclosures of the same size, it is possible to achieve more subwoofer cone surface area with a square design than a circular design. "Live at Red Rocks" was released to combat this, as it was an affordably priced, high quality alternative to poor quality, overpriced bootlegs. The intent of a square subwoofer is to increase the surface area of the woofer's cone. Bootlegs were sold in the early 90's, a cause for concern for the band. However, they can be useful in creating unique 'looks' in a car audio system that is meant to be seen as much as heard, and to create brand distinction and recognition. The band cites college students trading tapes in the early 1990s as a key reason for their current fame. There is no known auditory advantage to these shapes. The Dave Matthews Band allows audience members to record their live shows, as long as shows are only used personally or traded for no profit. Other companies, such as Sony, have jumped on the bandwagon, producing non-round subwoofers of their own. It is perhaps more accurate to state that the band's music (and that of the many bands influenced by it) is a breakaway sub-genre of jam band, known as Shitrock--an obviously self-conciously jocular term now borrowed by such luminaries as Clyde Wagner and Radiohead (in the style of many such acts, DMB is taper-friendly). Xtant has introduced a hexagonal subwoofer. Songs would thus be drawn out to facilitate these longer gigs. Bazooka has introduced a triangular subwoofer. In the band's earlier years, song arrangements were looser and many of the lyrics were not set in stone; additionally, DMB's repertoire was not increasing as quickly as its number of gigs or allotted stage time. Stillwater Designs, nicknamed Kicker, released a square subwoofer several years ago, the Solo-Baric series, and recently, the Solo X. While members of the group have been known to engage in extended improvisational solos, this by itself is hardly a quantifier for the label. Within the last few years, the car audio field has seen a variety of subwoofers utilizing non-round shapes. Arguments have raged throughout both DMB's fanbase and online communities dedicated to discussing bands such as Phish and the Grateful Dead as to whether or not they are a true jam band. Some waterproof models work underwater, or placed on the underside of a deck, to create sound. No one knows if this is true, but if it is, the album would likely come out in the fall, setting up a winter tour. They can be placed on a large flat surface create a large, though poor, loudspeaker. Rumor has it, that the band will be back in the studio in the late winter/early spring. These devices typically don't provide as much vibration per dollar as simply placing a reasonably priced subwoofer against the back of the furniture, so at their current prices are most useful for not disturbing anyone than vibrating to audio. "The Complete Weekend On The Rocks," a box set of all four Red Rocks concerts, is also exclusively available from DMB's official store. However, some feel that the vibrations are a little disembodied from the rest of the auditory experience. The 2005 Red Rocks concerts were released on November 29 as a "best of" CD/DVD combo entitled "Weekend on the Rocks". These have recently emerged as a device, called a tactile transducer by at least one brand, that attaches to furniture, such as one's seat, via which vibrations are transmitted to the body; they can be connected to an amplifier as per a normal loudspeaker. Dave Matthews Band embarked on a brief tour in the fall of 2005, with dates throughout November and December. Since much bass is felt, sub-bass can be augmented using tactile transducers. The proceeds from the fourth Red Rocks show, which totalled over $1 million, went entirely to the victims of Hurricane Katrina. Indeed, hearing loss is one concern, alongside space considerations and neighbour relations. Old and new fans alike were delighted. Such "SPL wars" have drawn much attention to subwoofers in general, but subjective competitions of sound quality ("SQ") has not gained similar popularity. Although the song is rarely played, the band gave into the chant and played an impromptu version of it. Naturally, these sound levels are not safe for humans. On the third night of the stand, the fans started a massive "Halloween" chant, a favorite song off the album Before These Crowded Streets. In international car stereo competitions, over 100 subwoofers driven by some 100,000 watts have been used to generate over 180 decibels. Fan reaction towards the hip-hop influenced album was generally poor and the album spawned the hit singles "American Baby," "Dreamgirl," and "Everybody Wake Up." The band supported the album with a summer-long tour culminating in a four-night stand at Red Rocks Amphitheatre, where they recorded their first live album ten years earlier. Curiously, some car stereo enthusiasts seem intent on producing ultra-high sound pressure levels in the confines of their vehicle's cabin. Stand Up was released on May 10, 2005, debuting at #1 on the Billboard charts with sales of 465,000. Typically, subwoofers are installed in the trunk. The negative reaction of many of its fans to Everyday and the middling success of Busted Stuff, coupled with Dave Matthews' belief that the band has not made a great album since Before These Crowded Streets, all worked to create a sense of eagerness, if not urgency, on the part of the band to create a stellar album. The automobile is ideal for the "hidden" subwoofer approach due to space limitations of locations such as doors (ignoring the acoustic problems of a car interior). The band considered itself to be at a crucial crossroads in its evolution. All of these subwoofers tend to have in-built amplification. In the fall of 2004, the Dave Matthews Band returned to their studio in Charlottesville, Virginia with a new producer, Mark Batson. These can be purchased separately, to be added to an existent system or when considering a set of speakers; or as part of a high-end speaker package. In August 2004, the band became notoriously famous for dumping up to 800-gallons of their raw human waste from their tour bus through the Kinzie Street Bridge in Chicago onto passengers aboard a sightseeing boat below.[1]. On the other hand, high-end domestic subwoofers are manufactured by companies such as M&K, HSU, Velodyne, SVS, and REL. "Joy Ride" received a few small teases over the course of the extensive touring year. Further, small satellites systems typically cross over the bass above 90 Hz, introducing the subwoofer "localization effect". The other songs that debuted during the summer of 2004 -- "Crazy-Easy," "Good Good Time," "Joy Ride" and "Sugar Will" -- were all absent during the duration of the 2005 touring season. They are too weak to play any real deep bass. The second release, DMB Live Volume 2: 9.12.04 Golden Gate Park, included the guitarist Carlos Santana and gave fans previews of newly-penned songs "Joyride", "Hello Again", and "Sugar Will", all at the time presumed to be destined for release on a 2005 new studio album, though only "Hello Again" was actually included on the release of Stand Up. Most multimedia "subwoofers" should probably have been called "woofers". The first such release, DMB Live Volume 1: 12.8.98 Worcester, MA, featured guests Tim Reynolds, Béla Fleck, and Jeff Coffin and had been nearly universally accepted as one of the greatest shows in the Band's history; however, such talk has subsided after its release. Particularly among low cost systems, however, it may be little more than a marketing device: it's not likely that a small woofer in a compact cabinet will have better bass performance than good speakers; as mentioned, the term "subwoofer" is no guarantee of particular bass performance. Later in the year it was announced that highlights from the Band's extensive live archives would be available for purchase via the official website. The physically separate subwoofer/satellite arrangement has been popularised by lifestyle systems, such as those manufactured by Bose, and multimedia speakers, examples of which include the Klipsch ProMedia. The Band also exclusively released a 6-disc CD set from the same run featuring all three nights, with each night spanning across two CDs. ("Bass management" or "Small" mode for the satellite speakers is common among equipment such as Dolby Digital surround processors/receivers.). In June, "Dave Matthews Band: The Gorge", a combination 2-CD/1-DVD set with highlights from their 3-night tour closer at The Gorge in George, WA from 2002, was sold in stores. All low frequency information is sent to the subwoofer. 2004 saw the band release more music than any previous year. Note that only one subwoofer need be used, even when using 5 or more satellite speakers—e.g., for surround sound. A live recording of that show was released later that year as The Central Park Concert on CD and DVD. Harmonics at higher frequencies (from the satellites) can then be used, by the auditory system, to calculate the directional information. On September 24, 2003 Dave Matthews Band reached another milestone in the history of the band when they played a free concert on the Great Lawn in Central Park, New York City to benefit New York City schools. (e.g., it has been suggested subwoofer(s) be placed in the corner of the room, far from large room openings, and closer to the listener.) This is possible since low bass frequencies have a long wavelength; hence there is little difference between the information reaching our left and right ears, and we are unable to easily locate their direction below 90 Hz. The live release highlighted songs from both Everyday and Busted Stuff. Physical separation of subwoofer and "satellite" speakers not only enables placement in an inconspicuous location, but since sub-bass frequencies are particularly sensitive to location (e.g., due to room resonance and 'modes'), the best position of the subwoofer may not be where the "satellite" speakers are located. Later that year the band released its fourth live album, Live at Folsom Field, Boulder, Colorado, recorded July 11, 2001. (e.g., some speakers include a subwoofer in the lower portion of the cabinet.). Busted Stuff received moderate critical and commercial success and was generally well-received by the band's fanbase. Thus, subwoofers may be part of a package that includes satellite speakers, purchased separately, or built into the cabinet of a conventional loudspeaker. Produced by Stephen Harris, the recording engineer under Lillywhite on previous albums, the resulting CD provided new treatments of much of the Lillywhite Sessions material, along with newly written songs "You Never Know" and the hit singles "Where Are You Going?" and "Grey Street". Rather, the intention may be to use small main ("satellite") speakers (of which there are 2 for stereo, and 5 or more for surround sound) and locate ("hide") the subwoofer elsewhere; to augment an existent speaker to relieve it of reproducing bass and gain output level and/or quality; or because high levels of low bass are required and using a dedicated amplifier and speaker provides the output level and quality required. In response to overwhelming fan support, coupled with a popular and widely publicized online campaign known as the Release Lillywhite Recordings Campaign, the band returned to the studio in 2002 to record Busted Stuff. A conventional woofer may reproduce frequencies up to 200, 300, or in a two-way speaker a mid-woofer (paired with a tweeter) also handles midrange, up to 3,000 hertz or more. The Lillywhite Sessions would, however, finally have their chance to shine. It should be noted that a subwoofer does not necessarily provide superior bass performance to large conventional loudspeakers; they are merely subwoofers because they ought to reproduce only the lowest frequencies. Tracks such as "Bartender", "Grey Street", "Captain", and "Grace is Gone" caused many to wonder aloud whether the band had thrown away its best (albeit unfinished) work. Considering they operate outdoors and the average listener is hundreds or even thousands of feet away from the devices, they are impressive. After critical comparison of the two simultaneous albums, many fans were frustrated with the band's decision to scrap the work in exchange for "Everyday". People who are accustomed to bass in home audio systems and car audio many times think that the subs in a concert PA system aren't putting out that much. Better known as The Lillywhite Sessions, this rough album was universally lauded by both the fanbase and the popular press. On average, music applications generally require less capability than movie soundtracks in the very lowest octave, but modern popular music is changing this preconception and this is reflected in the design attention given to the subwoofer section of the PA system nowadays compared to a couple of decades ago. Over established internet channels such as the Dave Matthews Band Mailing List, the tracks spread like wildfire. Pro Audio subs have to be capable of very high output levels – after all, concert venues may seat 10,000s of individuals outdoors. The conflict came full circle when, in March of 2001, the 2000 studio sessions with producer Steve Lillywhite were leaked on the internet. A large horn-loaded version called the BassTech-7 can be found in venues such as theme park rides. Its poppy, slick sound (including Dave Matthews' first ever recording sessions on electric guitar) was a great departure from the band's previous work and the complete antithesis of the songs recorded with Lillywhite. Another extreme pro audio device is the ServoDrive ContraBass, where the driver's cone is moved using a belt-drive coupled servo motor. But like the band itself, the fanbase was disappointed with the release. Intended for applications such as night club installations and concert sound reinforcement this cabinet is still popular with PA system equipment rental companies. The February 2001 release of Everyday was a huge commercial success—the singles "I Did It", "The Space Between" and "Everyday" gained the band an even larger level of popularity. A now-discontinued but popular Electro-Voice subwoofer employs a "Manifold Technology" configuration to fit four 18-inch drivers into a relatively compact enclosure. Drummer Carter Beauford's sarcastic jibe that the band had "charts and everything" ready for them shines light on a session where the band, which had in the past collectively composed its music, was turned into a backing band for Matthews with no creative input. One of the most powerful subs manufactured can play as low as 25 Hz and can cover thousands of feet and uses two 12-inch woofers on a 13-foot (4 m) long folded horn (the EAW bh822e or KF940). In the end, the album was completed but the band seemed unsatisfied. 12-inch drivers in very large folded horns are also becoming popular now. While the album gave the band a much-needed fresh start, Ballard's slick pop-music approach to production was very different from the creative process used to produce previous studio albums. For electronic music events with at least a thousand audience members there are often more than 20 double-18-inch cabinets on either side of the stage. The band soon joined Matthews in a Los Angeles studio, quickly recording what was to become Everyday. They are usually direct radiating in a ported enclosure built of 13-ply birch. In October 2000, an energized Matthews began writing with Glen Ballard, most famous for his work with Alanis Morissette. The 18-inch woofer driver is the primary majority device for pro audio applications. Some believe the band was unhappy with the atmosphere of the songs and frustrated with Lillywhite's often perfectionist style of production, while others believe Lillywhite was made into a scapegoat for the band's lack of professionalism during the recording sessions. Similar popular PA systems are made by JBL, Electro-Voice, EAW and Meyer Sound. In August of 2000 the sessions were scrapped and the band's seven-year relationship with Lillywhite was over. Popular sub systems in use currently are made by companies such as EAW but usually the subs will be made by the manufacturer of the rest of the PA system such as L-Acoustics and their V-Dosc Line Array with its matching dual 18-inch sub cabinets. In the end, the studio sessions were a failure. Many times the subs are not part of the entire sound mix but are specifically fed just kick drum, bass guitar and other low-frequency content from a separate output on the main mixing console. The band's attentions wandered during the seemingly never-ending recording sessions; they spent more time riding four-wheelers through the countryside and playing video games than writing or recording music. Similar systems are used in theme park rides, such as "Days of Thunder," which uses sound to simulate a physical impact. Heavily influenced by personal conflicts, notably the death of his uncle and his resulting alcoholism, the songs recorded with Lillywhite rank as some of the darkest Matthews has ever written. This was simply a set of large sub-woofers designed to create infra-bass (felt but not heard). With longtime producer Steve Lillywhite at the helm, the band began work on a fourth studio album. An unusual example of the use of sub-woofers came with the release of Earthquake in 1974 where they used a system called Sensurround to create a feeling of an earthquake. During the year 2000, the band set up its own recording studio in a large house in the country outside Charlottesville, Virginia. The bulk of the sound system is usually "flown" (suspended from the ceiling by chain hoists) and the subs are usually stacked on the stage or the ground in front of the stage to the left and right of the performance space. Instead of relying on upbeat hit singles, the album as a whole stunned many with its complexity and would be regarded as the band's greatest studio effort.(disputed — see talk page) In 1999 Dave Matthews released a solo live album, Dave Matthews and Tim Reynolds Live at Luther College, from a 1996 acoustic concert played by Matthews and longtime friend guitarist Tim Reynolds, and the band released a live album, Listener Supported, a concert from September 1999 that was also partially shown on PBS. Large concert sound systems always use subwoofers (referred to as "subs" by the engineers and crew). Before These Crowded Streets represented a great change in direction. Note that movie theatre speakers (situated behind a perforated screen) typically use 15" drivers (woofers), so the use here is only to reproduce the lowest frequencies at high sound pressure levels. In late 1997 the band returned to the studio with producer Steve Lillywhite and an array of collaborators, including banjoist Béla Fleck, vocalist Alanis Morissette, guitarist Tim Reynolds, keyboardist Butch Taylor, and the Kronos Quartet, to compose and record Before These Crowded Streets, their third album with RCA. Some of these applications require subwoofers designed for very high sound levels, such as the JBL 4645 – certified for THX movie theatres – which uses an 18" driver (woofer). This album featured popular songs from the band's three previous albums and included longtime collaborator and guitarist Tim Reynolds. Subwoofers are found in professional applications such as live concerts, movie theatres, various other sound reinforcement applications (ranging from nightclubs to theme restaurants) and studios. To combat an increasingly and illegally profitable bootleg market, the band released a live album, Live at Red Rocks 8.15.95. This track is often used aggressively by mixing artists. By 1997, the band had reached great popularity across the country and, to some degree, the world. The .1 channel is usually dedicated to extended bass frequencies, for example, the low frequencies of a gunshot, string bass, or thunder. Featuring the hit single "Crash Into Me", as well as fan-favorites such as "Two Step", "Tripping Billies", and the Grammy-winning "So Much to Say", Crash would go on to be the band's best selling album. The need to reproduce these frequencies has increased since older formats, such as vinyl records, have been displaced by digital formats, such as CD, and particularly 5.1 formats such as Dolby Digital, in which the ".1" channel is dedicated solely to the subwoofer. For most of America, Crash was the record that put the Dave Matthews Band on the map. Subwoofers are usually powered by a high power amplifier, and often an electronic crossover ensures that higher frequencies will not be directed to the subwoofer. This was followed by Crash (1996). Diameter tends to be advantageous because low frequencies involve shifting a great deal of air; a recent trend has been for high excursion, i.e., how far the cone can linearly travel from its resting position; for example, some can move as much as 2.5" in or out, yielding an overall displacement of 5" (this is controlled movement range). Under the Table and Dreaming would be the first of three albums released under Lillywhite's direction. Subwoofers use drivers (woofer) with cones typically coming in 10" or 12" sizes, but can be as large as 34", and as small as 4". (Keyboardist Griesar left the band in 1993, shortly before the release of "Remember Two Things".) After signing to RCA Records, Dave Matthews Band, under the direction of producer Steve Lillywhite, released Under the Table and Dreaming in 1994, a critical and popular smash that firmly established the band's style of pop-rock with improvisational leanings. . In the early 1990s, the band established a cult following through relentless touring with weekly stops at Virginia clubs known as Trax and Floodzone, an active taping community, and an independent LP, Remember Two Things. It is difficult for small loudspeakers to reproduce frequencies below 40 Hz, especially above 100 dB, and so it is often advantageous to use a loudspeaker dedicated to this task. The Grammy nominated album "Under The Table and Dreaming" is dedicated to her. So-called subwoofers which reproduce frequencies from about 35 Hz to about 150 Hz are more properly described as bass modules than true subwoofers. In 1980, the family moved to South Africa where the young Matthews went to several schools and "got more wise about the evils of government, there and in general." In 1994, his sister Anne died in a domestic tragedy at her home in South Africa. Frequencies 16 Hz or lower are more felt than heard. The family returned to New York where his father died in 1977.
