In 1946, J.B. Lansing formally established JBL. The purpose at that time was to manufacture a household system comparable to monitor speakers. Unexpectedly, JBL would later enter the professional market to get a share of the pie. Early JBL masterpieces, such as Olympus, Hartsfield, Paragon, etc., are not only luxurious in shape, special in structure, but also fascinating in sound. They are still the target of players' collection today. Paragon is more like elegant antique furniture, Hart produced since the early 1950s
The sfield is mostly used in theaters and other large-scale occasions. In the past few years, fans made it reborn, forming a story. Two Michigan enthusiasts, Mark Weiss and John Wolff, teamed up a Classic Audio Reproductionds. They reproduced a new Hartsfield with updated technology and monomers. Thanks to the addition of a super high-frequency extension, the crossover has been improved, naturally and The old Hartsfield will have some differences. However, the elegant and large appearance, as well as the relaxed and natural charm are all nostalgic. Hartsfield recommends placing it in the corner, but it is different from the structure of Klipschorn placed in the corner. Klipschorn uses the wall as an extension of the bass folding horn. Without a wall, the low frequency will be affected; and Hartsfield is basically designed for easy placement. . What's interesting is that both of them later designed a wing-like backboard to facilitate the positioning needs when leaving the corner.
Like Electro-Voice, JBL’s large monitor speakers are mainly based on horn treble and cone bass. The Project K2 S9500 launched in 1989 uses two bass packages to clamp the horn. Due to the extensive use of new materials (glass horn, artificial Stone base, etc.), making S95 00 a brand new look. On the other hand, the small monitor speakers designed by JBL are also very popular. The L-100 launched in 1971 is the beginning. In recent years, the 4312MKII, the latest 4325MKII, and even the Century Gold commemorative speakers launched to celebrate the 50th anniversary. Both adopt similar concepts. These speakers have a strong personality, which feels very suitable for interpreting pop music or as home theater speakers. The meticulous expression, strong dynamics and clear transient response are exactly where JBL has become famous. JBL has another professional brand called Urei. Many large recording studios have used Urei 815. This is an active-designed product, which is equipped with a negative air and an amplifier. Urei's modularization concept is very novel. All speakers use the same specifications of JBL, and the speakers are only different in size. The structure and maintenance are very easy. In fact, adjustments require some thought.
PMC and ATC
PMC (Professional Montior Com.) is a British manufacturer that only sprang up in 1990. The designers Peter Thomas and Adrian Loader produced a series of speakers for studio monitoring based on the principle of transmission line speakers. From the largest BB5/XBD, there are many products such as MB-1, IB-1, AB-1, LB-1 and so on. Introducing PMC and ATC together, it is true that they have many similarities. Like the large MB-1 and BB5, the mid-to-treble part is simply a copy of ATC. The tweeter is a French Audax or Vifa product, and the bun-shaped midrange is developed by ATC. The bass is of different models and has different products. The biggest feature is that they are all designed with transmission line speakers, so they can be in a smaller volume. The ideal low-frequency extension effect is achieved within. Compared with ATC, PMC has the same thick mid-to-low frequency and weight, with excellent density, and the mid-range is particularly full. It can withstand high power (you must also use high power to drive), and it can also send out large dynamics. However, PMC is more sinking in low frequency than ATC speakers of the same size, and the speed is not too slow, which is quite suitable for use in the post-production process.
ATC was founded by Billy Woodman in 1974. He had participated in the design of B&W 801 and drew inspiration from there to complete the design of the SCM series in 1986. Billy Woodman proposed the unique theory of a large magnet, a large voice coil, and a short-stroke monomer. Especially in the bass part, its monomers are often customized, and one can weigh two others, and the pulp vibration is coated with a damping material. The membrane is also unique. Another achievement of Billy Woodman is the design of a 7.5 cm convex spherical midrange unit. This unit allows the mid-frequency of the ATC speaker to have a very linear performance, and it can withstand high power and sound full and strong. Starting from the more used SCM-100, there are SCM-200, and the Big Mac SCM-400. If it is not an active design model, ATC has launched its own brand of front and rear stages in order to apologize to everyone. Expand the machine to solve the problem that is difficult to promote. The SCM-50, SCM-20, SCM-10 and the smallest A7 introduced by ATC are mostly for household use. Their sound trends are roughly similar, and the cost of the amplifier is the same.
Yamaha and Diatone
Yamaha's audio department started with the manufacture of amplifiers. In 1974, the pyramid-shaped B-1 rear stage caused a lot of repercussions. The first speaker was the NS-690 in 1973, which was quickly forgotten. The NS model represents the Nature Sound advertised by Yamaha. The NS-10M, which is widely used for near-field monitoring, was born in 1977. The 3.5 cm dome tweeter and 18 cm white diaphragm bass are placed in a small speaker. It can attract many people and become one of the necessary small speakers in the recording studio (because it is also very cheap). The NS-10M was later modified several times. In 1987, the NS-10M Pro was launched, and the anti-magnetic MX Model was launched in 1993. In addition, there are also horizontal 10M Studio, NS-10MM, NS-10MT and other models that can be equipped with subwoofers. Developed out. A speaker is so popular, and its life cycle is so long, it is also a special case. In addition to this monitor speaker, Yamaha only has the subwoofer made by YST technology, and other speakers are almost completely wiped out. Even the flagship speaker NSX-1000, which was manufactured in 1986 to promote the prestige of the country, cannot escape this fate.
Diatone, which started with the manufacture of magnets, is a subsidiary of Mitsubishi Electric and has been manufacturing monomers since before World War II. The well-known 2S205 and 2S305 are manufactured in accordance with NHK broadcast technical specifications, which makes them secure the throne in the field of monitor speakers. Later, Diatone worked hard in the household market on the one hand, and continued to study in the professional field on the other hand. Those with 2S before the number were for professional use, and DS was for household products. Unlike European and American manufacturers, Diatone has spent a lot of effort on the improvement of single materials, and has tried many new materials over the years, such as LCP diaphragms that are twice the speed of sound. Starting from the DS-V9000 in 1988, the boron diaphragm (B4C) tweeter unit jointly developed by Diatone and NHK was officially launched, and the extension is very good. The mid-bass unit has a three-wire interlaced honeycomb structure, plus their magnet structure called ADMC, which forms the basis of most Diatone speakers today. The biggest feature of the Diatone monitor speaker is its super resolution ability. The change from the smallest volume to the strongest sound can be heard clearly, but some people think the taste is too flat, as if drinking plain water.
Rogers, Harbeth, Spendor
These three British manufacturers have a close relationship with the BBC. The person in charge or designer has worked for the BBC and then came out to independent portals, so from their products, you can vaguely hear the same pedigree and personality. In 1947, Jim Rogers founded Rogers Company in Hampstead. At the beginning, he only produced Williams vacuum tube amplifiers and helped a company manufacture marine communication equipment. It was not until 1954 that the company moved to Woolwich that Rogers began to produce speakers. In the early 1970s, Rogers began to cooperate with the BBC. The LS3/5 launched in 1974, using the KEF T-27 tweeter and the B-110 bass speaker, began to bring revolutionary changes to the small speaker. Rogers also because of The first production of LS3/5 has a history. Since then, Rogers has successively launched several BBC speakers such as LS5/8 and LS5/9, and has also developed many wonderful household products under the leadership of designer Richard Ross. Later, Richard died and Rogers changed hands several times. Now the boss behind the scenes is already a multinational group. They plan to promote Rogers as the British Bose, but it hasn't been effective for the time being.
Alan Show, which originally served at NEC, bought Harbeth, founded by W. Harwood in 1986. W. Harwood was originally the director of the BBC Research Center. He led the development of LS5/5, LS3/5A, LS3/7, LS5/ 8 and many other BBC-specification speakers. Harwood was the first designer to use plastic paper cones. He took the lead in applying them to LS3/4 and LS5/5. In the early 1970s, he obtained a patent for polylipid compounds and sold this patent to CBS. Later, CBS appeared to all Manufacturers who use multi-element materials to make monomers claim an interesting story. After leaving the BBC, W. Harwood discovered the TPX material produced by a French company, which is the lightest thermal plastic. He used it on HL Compact, HL-5 and other speakers to get top-notch sound. After taking over, Alan Show has always wanted to get rid of the shadows of the past, launching the HL-P3ES that replaces Ls3/5a, and the popular HL Compact 7, which now also joins the LS5/12A manufacturing lineup.
Cughes Spendor, a former Harwood colleague, founded Spendor about the same period. In the early days, Spendor still produced BBC-specification speakers, the famous SP-1, which was favored by many people. But after Spendor's death, his son Derek Hughes did not manage well and sold the company to the Soundtrack Group. Derek concentrated on the design, and the G-1000 came from his hands. There are not many Spendor products. In addition to the LS5/12A, the currently active monitor speakers also have a SA350, which was originally an active speaker designed for the German Broadcasting Corporation and looks a lot like the Spendor G-450.
Dynaudio Acoustics and Dynaudio
Dynaudio Acoustics, its parent company is Dynaudio, the most famous monomer manufacturer in Denmark. Since Dynaudio launched its flagship Consequence in 1989, they have established their reputation in the manufacture of loudspeakers. In the following year, the famous British monitor loudspeaker designer Andy Munro cooperated with Dynaudio to establish Dynaudio Acoustics, a company specializing in the production of loudspeakers for recording studios. The company is located in London, and the two companies are closely related but operate independently. Of course, Dynaudio Acoustics speakers will use Dynaudio's single-unit speakers, and they are the top ones. Including Dynaudio's famous bun-shaped midrange, the largest M3 uses two midranges and two bass. Because these monomers are not easy to promote and the structure is similar to ATC, the competition between the two is very fierce. The strange thing is that Dynaudio Acoustics and Dynaudio use the same monomer, but the sound is significantly different. The former is more straightforward and powerful, while the latter is slender, transparent and light.
Dynaudio speakers are divided into Confidence, Contour, Audience series, in addition to Facette, Craf ft, Micron and other independent models of speakers, BBC specifications LS 5/12A is also produced by Dynaudio. Regardless of the model, the impression of Dynaudio speakers is that they often don't have enough food, and the amplifier's current seems to be squeezed out, so it is not easy to make a good sound. For this reason, Dynaudio has launched front and rear amplifiers with amazing prices. The design and driving force are invincible, but does it mean that only speakers such as Consequence are used with such a good amplifier? What a pity, so Dynaudio is preparing to launch a pair of super flagship Evidence, the original factory is called "Formula One" (Formula One), two meters tall, sharing eight monomers on one side, the speakers and crossover are extremely luxurious Capable.
Music is the art of sound. There are all kinds of sounds in nature. Countless musicians in the world are very good at capturing the beautiful notes of nature and have written countless immortal music chapters. It comes naturally".
This is the first to talk about the monitoring equipment, which is the sound reproduction system that can more realistically restore the appearance of the original recording. Its basic requirement is neutrality and truthfulness. Of course, no device can achieve 100% restoration, but it is their goal to avoid sound staining and distortion under large dynamics as much as possible. As an important member of this system, monitor speakers are naturally responsible for replaying the original recording.
Misunderstandings about monitoring: Many people, especially some HIFI enthusiasts, think that because the monitor speakers are rational and have no flavor, the flavor is what we often call coloring and coloring. So these unsound speakers are not good to hear. In fact, we should consider this issue from the sound source as the starting point. If the recording level is poor, even the singer is not that good, it will not be good to play the sound with monitor speakers. Think about it from another angle, who wants to be intoxicated. In such a voice? Conversely, if the singer level and recording work are very good, then what will happen to this kind of music playback using monitor speakers?
General speakers have their own characteristics. For example, some of the sounds are sweeter and some are more refreshing, but as a recording monitor or users who require the reproduction of the original sound, this is unacceptable, so they will use monitor speakers. Generally more expensive than speakers of the same level.
Speaking of monitor speakers, many people may have heard of them in the field of professional audio, and they are still very unfamiliar. This starts with the classification of speakers. Speakers can generally be divided into main playback speakers, monitor speakers, and return speakers according to their uses. The main sound box is generally used as the main sound box of the sound system to undertake the main sound playback task; the return sound box is also called the stage monitor speaker, which is generally used on the stage or dance hall for actors or band members to monitor their singing or playing sound. The monitor speakers are used for monitoring when producing audio programs in listening rooms and recording studios. It has the characteristics of small distortion, wide and flat frequency response, clear sound image, and little modification of the signal, so it can reproduce the original appearance of the sound most truly.
The sound engineer needs to hear the essence of the sound, so that he can know how to modify the sound to achieve perfection. If it starts to hear, it will be extra"
