How to identify the quality of a speaker? Preliminary understanding of speakers before audition: observation technology: common speakers are decorated with a thin layer of wood skin on the surface of MDF medium density fiberboard: real wood skin, beautifully decorated speakers, especially rare wood skins such as rosewood, bird's eye, pear, walnut, nanmu and red oak. It has excellent natural wood grain visual effect and smooth and comfortable feel. Especially those pianos polished with symmetrical butterfly pattern solid wood skin after multi-layer coating can be regarded as high-end boutique speakers, and there are very few counterfeit products. Boxes covered with PVC (Shabili) plastic belong to daily necessities. Although the workmanship is fine, it is best to only
Weight: Good speakers mostly use 18 ~ 25mm high-quality MDF particle board, while high-grade flagship speakers use overweight solid wood such as mahogany and yellow pomelo or multi-layer composite plywood, which is amazing in weight. Usually, the net weight of a pair of speakers reaches 50 or 60 kilograms. Most middle and low-grade customers eat soft particleboard, while fake and inferior products use inferior paper rubber board, so the weight is generally light. There is often a saying in the audio industry that "experts look at quality, laymen weigh it", and heavy speakers are definitely better than light speakers. However, it is necessary to be wary of unscrupulous merchants pouring sand and cement at the bottom of the sound body to gain weight and deceive consumers.
Knock on the box: knock on the front, back, left and right baffles of the box with your knuckles. The box is heavy and slightly brittle on all sides. It feels that the plate is hard and thick, supported by multiple internal ribs, the box structure is reasonable and firm, and various sound insulation and standing wave prevention measures are adopted. This kind of box has high processing cost and great difficulty, and there are few fake and shoddy products. If you hit the box with your knuckles, it will make a "poof, poof" empty sound, indicating that the plate is too thin, the material is too poor and the structure is unreasonable. And there are no sound absorbing materials and reinforcing ribs inside, which leads to a large number of diffuse reflection and standing waves in the box. You will never get a good playback effect if you buy this kind of speaker.
Logo recognition: truly excellent speakers have well-made gold-plated or chrome-plated signs, which are generally engraved with distinctive trademarks, companies, names, places of origin, corresponding indicators and so on. Imported boxes are all in English, such as: Madeinxxx or Manufacture, corresponding trademarks, speaker indicators, etc. If only the design ... (XX design) or only a country name is vaguely marked, even apart from a few simple and extremely imprecise basic indicators, neither the place of origin nor the manufacturer can be seen, and the trademark has no registration mark. Most of these three products are suspected of counterfeiting. Brand spokesmen attach great importance to brand image and corporate awareness, so the signboards posted are very standardized and exquisite, and all indicators, corporate names and places of origin are readily available. Some signboards are even thin metal plated with 24K real gold, and the fonts on them are still uneven. The product not only has the date of manufacture and production serial number, but also has the matching serial number and the ID card attached to the packaging box. For this kind of speakers, as long as the quotation is reasonable, you can generally choose with confidence.
Judging the advantages and disadvantages of speakers from technical indicators
Flexibility: The most important indicator of the speaker largely determines what kind of power amplifier the box should be equipped with and how much power is needed to drive it. The flexibility of most audio-visual home speakers is between 86-92dB. For the same power amplifier, at the same volume (for example, adjust the volume to 10), the higher the flexibility and the higher the sound, the lower the power requirements and requirements for the power amplifier. This is what people often say: speakers are easier to push. The elasticity of professional speakers used in many commercial OK halls is more than 100dB, so it is no wonder that many people think that singing karaoke in OK halls is very pleasant and you can get a lot of volume without blowing off dust. Don't think that the higher the elasticity, the better. Speakers with flexibility exceeding 92dB are all thin metal pots and PP pots, which will destroy the control of speakers, resulting in thin, beautiful, exaggerated and tough sound quality, and lack of many musical details and charm. Not suitable for high-fidelity listening. And many famous mouths with rich and soft voices and full of music are usually less flexible. For example, the flexibility of top speakers such as Emperor ATC, Italian piano and Li Zhuo is only 82dB. This kind of speaker is often extremely difficult to serve, and it needs a giant power amplifier with a large output current to make it work in an ideal linear region, and the price will never be small in the frequency range: for example, the frequency range of the domestic boutique Xindeke Compass No.1 bookcase is 60Hz ~ 20 kHz 2.5 dB, and 60Hz represents the extension value of the speaker in the low frequency direction. The lower this number is, the better the low-frequency response of the speaker is: 20KHz represents the high-frequency spread that the speaker can achieve. The higher the number, the better the audio characteristics. The suffix +/- 2.5dB indicates the distortion of the above frequency range, and the smaller the distortion, the flatter the frequency response curve will be. The distortion of some speaker labels is 3dB, and its frequency range should be wider. Some speakers do not indicate this indicator, and the frequency expansion range will become very wide. For example, if the distortion of the compass box 1 is not indicated as plus or minus 2.5 dB, the frequency range can be marked as 40 Hz ~ 23 kHz. It should be pointed out that it is meaningless not to mark the frequency range of distortion. If manufacturers knowingly commit crimes, they can only suspect that they have ulterior motives and deliberately deceive consumers. At the same time, it also shows that the speaker indicators are not standardized, manufacturers lack confidence in their products, and it is difficult for people to buy with confidence. Carrying power: the reference index of the loudspeaker, expressed in watts. This index does not indicate the quality of speakers, but only provides a reference for the selection of power amplifiers. For example, the bearing power of a pair of speakers is marked as 10 ~ 200W, which means that the power amplifier needed to drive the speakers must have at least 10~200W output power, but it is forbidden to use a power amplifier larger than 200W for full power output. Otherwise, there may be concerns about burning boxes. Generally speaking, home speakers will never be pushed, only the problem of pushing well and pushing badly. The carrying power below 200 watts is much more than that of ordinary families, and it is not deliberately pursued too high. Impedance value: generally, the nominal value is 8 Ω, and the impedance value of most dual-frequency bookcases is 8 Ω. There are also multi-unit multi-frequency floor speakers with 6 Ω and 4 Ω. The smaller the impedance value, the greater the current to be driven and the higher the power amplifier required. In my opinion, it's best to choose a home speaker with a good 8 Ω impedance and a power amplifier.
? A good speaker should have obvious personality: American speakers pay attention to great power and great motivation. The wild and uninhibited character of the cowboy in the west and the infiltration of Hollywood culture and art, the speaker was produced in the west. It often shows a free and easy, rough and generous timbre personality. The timbre is bright and beautiful, the sound is clean and neat, and it can be opened and closed freely. In the bold and straightforward, there is a kind of confidence and confidence. The surplus of each index is very large, especially suitable for rock, jazz and heavy metal percussion, professional OK hall and other occasions. However, in violin solos and classical strings, the music is a little light. The speakers produced in the eastern part of the United States are more influenced by British and European civilizations because of geographical and environmental factors. In addition, the famous Philadelphia Symphony Orchestra advocates classical symphonies and influences regional culture with a large number of performances every year. Therefore, speakers produced in the eastern region, such as INFINITY and WestlakeAudio, have both soft and delicate styles and broad and bright styles. No matter from the analytical power, sense of speed, sound stage positioning and fragrance, it is obviously different from western speakers, and it is very popular in Europe and the Far East.
British sound box: It has typical European royal blood, soft and sweet timbre, dignified and elegant shape, flashy but not gorgeous, making British sound gentle, sweet, delicate, steady and gentle. It occupies a very high position in the field of family HI-FI and even Hi-END, and is most suitable for the performance of classical strings and the reproduction of human voices. Unfortunately, it is not effective in expressing large dynamic explosion scenes and low frequency sense.
German speaker: It fully embodies the meticulous, rigorous and self-disciplined professionalism of the German people. The timbre is natural, neutral and peaceful, clean and refreshing. Especially in the industry, it is famous for its exquisite workmanship, which is amazing. But strictly speaking, the timbre of German box is slightly tough in Leng Yan, which is more suitable for the playback of pop music.
Other European voices, such as France, Denmark, Italy, Sweden and Norway, are full of wit and romance in France, artistic flavor of the Italian Renaissance, liveliness and cheerfulness in Northern Europe and extremely exquisite traditional handicrafts: the timbre is pure and natural, with a slight exaggeration in the middle and high frequencies, but it is very musical. And good compatibility, it is the best choice for family HI-FI/AV. Domestic speakers: a few domestic products have formed their own style prototypes, but they can only be described as similar to a well-known brand in a certain country. Hivi, for example, is quite similar to American accent, while Ares series and classic series Xindeke are more reminiscent of British accent (although the explosion point and speed may be slightly stronger than authentic British accent). However, the small whirlwind and Jin Lang are more or less contaminated with European customs: only the bookcase "Canghai Longtong" carefully brewed by Mr. Zhang Bailiang has a unique flavor, with mild and neutral color, exquisite elegance, gentle and unrestrained appearance, and the traditional China soil paint is antique and natural, which really makes people feel a little "China sound". It is believed that based on the 5,000-year history of Chinese civilization, the ancient rhyme of the flat bell and Gong Yanxiong's muddy music from Xia, Shang and Tang Dynasties, as well as the unique implication, connotation and colorful feelings of China people, as well as the traditional cultural essence of Confucianism, Buddhism and Taoism, such as "moderation", "combining two into one" and "inaction", it is believed that in the near future, there will be a world-recognized "China Sound" application.
A good speaker should be very durable. When you turn on the stereo to enjoy music, you still feel that the timbre is good at first, and the sound is strong enough, especially the middle and high frequencies are bright and moving, and the low frequencies are also satisfactory. But after listening for a while, I felt uncomfortable. I was so tired that I had to turn off my cell phone and go. This kind of "tired" speaker can't keep the guests, because it makes people feel "noisy" and annoying. A "noisy" speaker means that the box is distorted and uncomfortable to listen to. Certainly not a good speaker. Listening to a good speaker with excellent quality is like tasting the daughter red of an old flower carving buried underground for 30 years. It feels sweet, refreshing and has a long aftertaste. That kind of "sweet" and "warm" music charm will make you forget time, space and even your own existence and indulge in the ocean of music. No matter how long you listen to it, you will never get bored. A good speaker has extremely low distortion. So no matter the volume, it will make you sound very pleasant. Even if the volume is turned up to the maximum power, the speaker will burst into earth-shattering sound. The low frequency will roll like thunder in midsummer, which will only make you feel realistic and even horrible, but it will never let you escape. Generally speaking, speakers with thin voice, hard timbre and fast speech are not very pleasant to listen to. We can be sure that it is caused by the thin speaker, poor sound absorption, simplified frequency divider and low grade speaker. Nature is not a good speaker. A good speaker is very resistant to listening, it can not only retain guests, but also the longer you listen, the more cooked you cook, the better your timbre will be.
A good speaker can hear the smallest information in the music background. A high-resolution box can contain a huge amount of music information, especially the information in the music background. So that people can hear more music details, harmonious aftertaste and multi-angle, multi-directional, diversified and multi-level music sound field through the theme unit. Listening to the first song "Forgotten Time" of Cai Qin (film number DJCD-96 108) recorded by Dianjiang, Taiwan Province, the first few words are cantata: "Who is knocking at my window and who is plucking the strings, then the forgotten time gradually lifts my heart ..." When a good speaker performs this passage, this song is a cantata. High-resolution speakers can even let you hear the subtle sound of the band flipping the score and the sound of the player's footsteps sliding gently on the ground during the performance. A good speaker can faithfully reflect and reproduce all kinds of signal sources recorded on the CD, can explode into colorful colors, can be slender enough to tremble in the air and can be invisible. So before choosing a speaker, prepare a CD with a lot of music information you are familiar with on weekdays. For example, Taiwan Province UFO Record Company recorded Zhu Zheqin's "Yang Jinma" (film number YT-84), which is a test disc with an amazing amount of music information. After listening to this disc, you can tell the destroyer Xuefeng whistling in the background by Zhu Zheqin's clear singing. The Himalayas pushed Chai Fei away and started a day's work through the creaking new snow in the morning. You can even hear several paintings of Beifeng Valley in Tibet very clearly. It is impossible for a speaker with poor resolution to provide such a rich music feast. Of course, when listening to the resolution of the speaker, you should be careful to use particularly explosive signal sources, such as artificial electronic synthesis blockbusters, strong shock of heavy metal rock music, percussion music and so on. The huge loudness will cover up the inherent shortcomings of many devices.
A good speaker can let you hear the accurate audio-visual positioning, that is, the pronunciation position of each instrument when playing. For example, in a large-scale symphony concert, speakers with audio-visual positioning will make you feel the orchestra display as shown in the following figure: the first violin and the second violin group are generally located on the left side of the stage, the piano and harp are behind the left side, the cello array is generally on the right side of the stage, and the double bass array is closely followed. In the center of the stage are viola array, flute, oboe, horn, bassoon, trombone, trumpet, percussion and timpani. A good speaker can accurately reproduce the sound field positioning with distinct layers. Under the guidance of experts, you can hear the sounds of various musical instruments coming from different positions in front of you, such as front, back, left and right, not just the mixed melody of various sounds from two speakers. Better speakers, auditioned in a professional audition room with strict acoustics and moderate size, you can even feel the unique sense of space and scene at the concert! Of course, as far as ordinary consumers are concerned, it is impossible to have such a good professional listening room for you. You can only choose speakers in the harsh acoustic environment randomly released by the audio shop. You can bring a few CDs that know the placement of musical instruments in advance, such as Yin Chengzong's piano concerto "Yellow River" played by Czech Radio Symphony Orchestra and conducted by Adrian Lipper: from the stage point of view, the piano is placed in front of the stage to the left, the cello is on the right, the double bass is on the right, the horn is in the middle, and the violin group is on the left. If you sit in front of the speaker and play back the recording, you should also be able to feel the sound field positioning effect very close to the on-site courtyard. That is to say, the sound of the piano is absolutely on the left in the middle. A good speaker should be able to hear that when the piano is solo, the treble is on the left and the bass is in the middle. At the same time, you will feel Yin Chengzong's hands jumping back and forth in the left and right position of the piano, which will produce a wonderful audio-visual movement. A poor speaker may hear the piano sound on both sides of the speaker at the same time, or the double bass that should belong to the right speaker will ring in the middle or on the left, causing sound field confusion. This kind of professional speaker is called poor phase characteristics or phase disorder. For another example, when listening to a CD vocal disc, both the left and right speakers emit human voices, but it feels like the singer is standing in the middle of the speakers and singing. This phenomenon is called spatial sound source image. A good speaker, such a sound source image can be felt by almost everyone. The best speakers can make you feel that this person is singing not far from you when you close your eyes, and even let you feel the height of the characters and the size of the singing mouth. This is also called "positioning".
