the first is the voice of the theater, ALTEC full-frequency
the voice of the theater was first devoted to the production of full-frequency speakers and coaxial speakers. The company's speakers and speakers were the vane of the world audio industry before the 198s, and the technology and design ideas crushed the global counterparts, and the speakers produced were all the objects to be imitated by everyone. From magnets to paper pots and even to horn overhangs, it is a model for industry learning. The full frequency produced by this company ranges from 6 inches to 15 inches, all of which are famous, among which the classics are 41C, 43A, 45A, 458B, 418B, 419A, 419-8B,42a and so on. But the most famous is 755E e. There are many versions of 755, the earliest version is 755A introduced by Xidian in 1947. In the early years, AR(Acoustic Research) launched the AR-1 speaker with WE 755A and its own bass monomer to stir up the sound circle. However, the 755A monomer launched by WE was discontinued shortly. Later, Altec continued the same technology and design and began to produce 755A in 1954, creating a series of 755 legends. The most successful product is 755E. This 8-inch loudspeaker with a frequency response range of 4-15KHZ has become the most famous full-range loudspeaker in the world. Because people who have heard it can't forget its charm, it's a unique taste of paper pots, plus the unique taste of Indox ⅴ iron core magnet and the unique taste of Xidian timbre, the data may not even be as good as the second-rate full-frequency speaker, but it is the most worthwhile full-frequency speaker in the world, because of its taste, you may not want to leave it for a day under the impetus of a one-watt single-ended courage machine. I remember I went to the home of a big fan in Guangxi. The home was a pair of 18-inch horns of the sound of the theater, and I could hear the earth-shattering effect, but he used 755e to listen to human voices. He said that no speaker could hear such a feeling.
the second is American Budweiser EV Full Frequency
Budweiser is an American horn manufacturer, which is as famous as ALTEC in the last world, and has a high technical level and market share. Unfortunately, it later focused on the professional audio neighborhood. This company's full frequency is also a wide range, and famous speakers are everywhere. There are many speakers from 6 inches to 15 inches. Excellent full-range speakers include sp-15B, SP-15, sp-12B, SP-12,SP-8B, MC-12, mc-8a, MC-8, LS-15, ls-12A, LS-8 and so on. He is also an expert in ferromagnetism with cobalt magnet and indox ⅴ iron powder core. Their full frequency is the best in the industry regardless of price or sound. Their excellent full frequency came from 197-1972.
The third one is American God of War JENSEN Full Frequency
This legendary American audio enterprise, founded in 1927, has absolutely decisive influence on the world audio industry. Although God of War's best coaxial horn even exceeds the sound of the theater, the full frequency is not his mainstream business, but the cobalt magnet of God of War also has the full frequency of excitation, which is an ultra-high water product in the industry. Many well-known guitar speakers used full-range speakers from the 197s to the 199s. Even the famous 18-inch, 15-inch and 12-inch moving magnetic high-priced loudspeakers of Xidian WE in the 194s were basically manufactured by the God of War, and the God of War produced the world's first truly coaxial loudspeaker, KM-15. Full-range speakers are not difficult for this legendary speaker factory with the most technology and the lowest key in America. It has everything from eight inches to fifteen inches, and many of them are branded with MAGNAVOX. Its full-range loudspeaker from paper to edge has a noble temperament, and it is bohemian and too individual in its splendor. Moreover, the full-frequency price of Ares is not high. After all, it is the originator of the foundry. Which foundry can sell at a high price? Let Foxconn try to make a mobile phone, but the quality is definitely good.
The fourth one is JBL, of course.
Needless to say, although JBL is now owned by Harman, JBL's brand is far more than Harman's. JBL is a pillar audio enterprise in the United States after WE Xidian. These pillars are the voice of the theater, Budweiser, Ares and JBL as I mentioned above. Before 198s and after Xidian, these four companies represented almost all the speakers in American audio industry. JBL speakers, like the above companies, do everything, and technology research and development is definitely the world leader. JBL's horn, as well as the big paper cone horn, are also top-notch in the world. It not only produces horns, but also its speakers are like Shaolin Temple in Chinese Wulin. JBL's full-range speakers are also advanced in many designs. All of them are single-basin speakers, and the dust caps are made of aluminum alloy. The first pair of voice coils has good heat dissipation effect, and the second sound spreads more than the paper basin dust caps. Later, it became an example and imitation object for the Japanese speaker industry, and also played a directional role in the development of full-range speakers in Japan. Its most famous full-range speakers are 2115, 2115A, 2115B, 2115H, 2115J and LE8T. Everyone knows the most about LE8T. In Japan, the value of this horn is like a god, as long as the speaker with this horn is not cheap, Shanshui, the most cattle audio company in Japan at that time, likes to make speakers with this type of speaker most. The F series of CORAL Coral in Japan and the F series of fostex are all imitations of LE8ET, so you can imagine the charm of this 35hz-15khz eight-inch loudspeaker.
Fifth auratone Full Frequency
Why do you talk about this brand? Because it only produces a full frequency of one size, and it is very famous. It is famous not because it sounds good, but because it is called the most ugly speaker in the world. You'll be famous if you do everything to the extreme. From 1958 to 25, AURATONE produced only one size full frequency, only 4.5 inches. He is the famous auratone 5c. During this time, Auratone improved the quality standards of the music and recording industries. It is more than 2 years earlier than the world-famous Yamaha White Basin. Since 197, it has been widely used in the 5C of major recording studios in the industry, and it is still the industry standard of reference speakers in recording studios today. It is used by the most famous old recording studios in the world. auratone is considered as the voice of premonition, and some big-name recording artists are using it. After the death of the boss Jack, auratone once stopped production. Those famous old users put forward the expectation that their family would continue to produce 5C, and Jack's grandson restarted the production of 5C in 212, which excited many old musicians and sound mixer. Who would have thought that when they first came into contact with 5c, they said that they might hear a fake monitor. Of course, auratone doesn't absolutely only produce 5C. In the past few decades, especially in the later period, they have also produced several crossover speakers, which are very popular among professionals with high sound quality and have become the collection of professional music producers, which are rarely seen in the market.
