How to buy speakers

As a terminal device for audio frequency, the speaker sounds like a human voice, which largely determines the quality of a set of sound. To draw an analogy: It is hard to imagine a person as strong as a cow but with a congenitally inadequate voice and incomplete pentatonic singing a beautiful song? It is therefore no exaggeration to say: Choosing a good pair of speakers is the key to the success of a set of sounds.

However, looking at the current audio market, there are hundreds of finished speaker brands, including many well-known international brands: such as American BOSE, JBL, INFINITY, Westlake Audio, and PolkAudio. (Sound): ATC (Ace), B & W, Tannoy, MonitorAudio, KEF, HARBETH (Dawn) in Denmark: DYNAUD10 (Danner), DALI (Dan) Nigeria), Jamo (Junbao): German Heco (German high), Mili (Maagnat), ELAC (intentional force); French Dream Voice (VIS10NACOUSTIQUE), JMLab (Jinlang): domestic boutique has a beautiful voice The God of War series, Jin Lang, Hivi, New Dirk, Gospel, Little Cyclone, etc., are numerous and numerous. The quality is uneven and the price is very different. Even for speakers of the same brand and series, the sound quality is often a little higher, and the price will rise several times. This is because since humans invented the electronic audio engineering, the only speaker has been the slowest progress and the weakest technology.

According to the British "Fever Book": A well-known British long-term Evergreen tree Rogersls 3/5 has been launched since the 1960s and sold well for nearly 40 years. Its pure and elegant tone is still a lot of senior Hi-Fi. Enthusiasts are regarded as hot and sought-after goods. Today, with the high development of audio technology, it is really puzzling. So don't underestimate the creation of speakers, don't think that speakers are just a few speakers and several Hi-Fi or Hi-END boxes.

The knowledge of the speaker is too big to be written, and there are many opinions about it. Just like the dispute between Chinese medicine and Western medicine in the medical field, or if it is to cure some incurable diseases: if you can't cure the disease clearly, you can't understand it if you cure it well. However, for consumers, we only need to learn how to identify and select. So is there a simple and convenient way to let most inexperienced consumers learn not to judge the goodness of a pair of speakers by relying on the "six points" of the speakers summarized below for you without relying on expensive prices and luck? Bad? Want to know the "six points" and listen to the next decomposition.

1. Preliminary understanding of the speakers before the audition

The initial understanding of a pair of speakers can be identified by the steps of "viewing, tapping, knocking, and identifying": that is, one view of the process, two pounding weights, three knocking on the cabinet, and four identification plates.

A view of the process: The view of the process is to judge the quality and quality from the first appearance of the speaker: the speakers made of natural logs are of course the best. Many world-class premium speakers of high price, including Chario (Zhuo in Italy) Li), Guarneri Homage (Mingqin), etc. However, due to environmental protection, lack of resources, difficult processing technology, long time and other factors, such good boxes will never be popularized as "rejoice" shampoo everywhere, the price is certainly not Law is low. Therefore, the common speakers are decorated with a thin layer of wood skin on the surface of MDF medium density fiberboard: speakers with real wood veneer exterior decoration, especially such as rosewood, bird's eye, pear, walnut, zhennan, red oak Such rare wood veneer, its natural wood grain visual effect is excellent, feel smooth and comfortable. Especially those who polish the piano lacquer with multiple layers of symmetrical butterfly patterned real wood veneer can be regarded as middle-to-high-end boutique speakers, with very few counterfeit products. Boxes made of PVC (Sapele) plastic are skinny goods. Although the workmanship is fine, it is best to count only the low-end goods. Although the box decorated with this patterned paper veneer seems to be extreme, pay more attention to whether the veneer seam behind the box body and the digging process of the installation position of the speaker are accurate. Counterfeit and shoddy products generally do not pay attention to these details, so you can judge correctly with a little care.

The second is the weight: the good speakers are mostly built with high-quality MDF particle boards of 18 to 25mm, and the high-end flagship speakers are built with overweight solid wood or multilayer composite plywood such as rosewood and yellow pomelo, so the weight is very amazing. Often the net weight of a pair of speakers is 50 to 60 kilograms. Most of the low-end and high-end goods use fluffy particleboard, and counterfeit and shoddy products use low-quality paper glueboard, so the weight is generally lighter. There is a saying in the audio industry that "professionals look at quality and layman weighs weight." Heavy speakers are definitely better than light speakers. However, it is necessary to be alert to unhealthy merchants pouring sand stone cement on the bottom of the sound body to gain weight to deceive consumers.

The third is knocking on the box: tapping the top, bottom, left, right, and front baffles of the box with the knuckles, all sides of the box make a solid and slight brittle sound, the texture of the board is hard and thick, there are multiple ribs inside, the box structure Reasonable and strong, with various effects such as sound insulation and standing wave prevention measures. This kind of box has high processing cost and great difficulty, so there are few fake and shoddy products. If the box is tapped with a knuckle to make a "pop, poo" sound, it means that the plate is too thin, the quality of the material is too poor, and the structure is unreasonable. And there is no sound absorbing material or ribs inside, which leads to a lot of diffuse reflection and standing wave formation in the box. If you buy this kind of speaker, you can never get a good replay effect.

The fourth is to recognize the nameplate: the really good speakers are quickly and well-made gold-plated or chrome-plated nameplate marks, there are generally distinctive trademarks, companies, names, places of origin, and corresponding indicators on the nameplate. The import box has English such as: Made in xxx or Manufacture and corresponding trademarks, speaker indicators, etc. If there is only Designin ...... (XX design) or ambiguity, only one country name is marked, even the simple and extremely rigorous basic indicators can neither see the origin, nor the manufacturer, and the trademark is not registered. . Most of these three non-products are counterfeit and inferior. Famous brand speakers attach great importance to the brand image and corporate visibility, so the nameplate markings attached are very standardized and exquisite, and all indicators and company names and places of origin are available. Some nameplates are even made of thin metal plated with 24K real gold, and the fonts on them have a bumpy feel. The product not only has a factory date, a production serial number, but also a paired serial number and an ID card. For this type of speaker, as long as the price is reasonable, you can generally choose it with confidence.
