How to buy speakers
As the terminal equipment of audio frequency, the speaker, like a human voice, determines the quality of a set of audio to a large extent. To make an analogy: It is hard to imagine a person who is as strong as a cow but has a congenital inadequate voice and a lack of pentatonic sound can sing a beautiful song? Therefore, it is no exaggeration to say: Choosing a good pair of speakers is the key to the success of a set of speakers, not to be sloppy.
According to the British "Fever Book": A long-established British brand evergreen tree phonology Rogersls 3/5 was launched in the 1960s and sold for nearly 40 years. Its pure and elegant sound is still used by many senior Hi-Fis. Audiophiles regard it as a hot seller. In today's highly developed audio technology, it is really puzzling. So you must not underestimate the speaker's construction, don't think that the speaker is just a few speakers and a few Hi-Fi or Hi-END boxes.
The knowledge of the speakers is too big to write, and there are different opinions from each family. Just like the dispute between Chinese medicine and Western medicine in the medical field, or the treatment of some intractable diseases: the one who can explain it can not cure the disease, and the one who can cure the disease can't understand it. However, for consumers, we only need to learn how to identify and select. So is there a popular and easy way to let most inexperienced consumers learn to judge the soundness of a pair of speakers not by expensive price or luck, but by listening to the "six points" of the speakers that are summarized below for you Bad? If you want to know the "six points", let's listen to the decomposition next time.
1. Preliminary understanding of speakers before audition
For the initial understanding of a pair of speakers, the steps of "viewing, weighing, knocking, and acknowledgment" can be used to identify: firstly observe the craftsmanship, secondly weigh the weight, thirdly knock on the cabinet, and four recognize the nameplate.
A look at the craftsmanship: The craftsmanship 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, and many world-famous supreme speakers with sky-high prices, including Chario from Italy Li), Guarneri Homage (名琴), etc. However, this kind of good box will never be as popular as the "Rejoice" shampoo that can be seen everywhere because of environmental protection, lack of resources, difficult processing techniques, and long time. The price is definitely not Law is low. Therefore, the common speakers are decorated with a thin layer of wood veneer on the surface of MDF medium density fiberboard: speakers with real wood veneer and exquisite exterior decoration, especially such as rosewood, bird's eye, rosewood, walnut, nannan, red oak And other rare veneers, the natural wood grain visual effect is excellent, and the hand feels smooth and comfortable. Especially the piano lacquer with symmetrical butterfly pattern real wood veneer is coated and polished in multiple layers, most of them can be regarded as high-end quality speakers, and there are very few counterfeit products. Boxes made of PVC (Sapele) plastic are of the general market. Although they are exquisite in workmanship, they can only be considered as low- and medium-grade goods. Although the boxes decorated with this paper veneer look extremely, you should pay more attention to whether the leather joints on the back of the box body and the digging process of the speaker installation position are accurate. Counterfeit and inferior products generally don't pay attention to these details, so you can make a correct judgment with a little care.
The second is to weigh: good speakers are mostly made of high-quality MDF particle boards of 18-25mm, and high-end flagship speakers are made of super-heavy solid wood such as red sandalwood and yellow grapefruit or multi-layer composite plywood, so the weight is very amazing. The net weight of a pair of speakers is usually fifty or sixty kilograms. Most of the mid-to-low-end and large-scale goods use soft-textured particleboard, and the counterfeit and inferior products use inferior paper rubber sheets, so the weight is generally lighter. There is often a saying in the audio industry that "experts look at quality and laymen weigh weight". Heavy speakers are definitely better than light ones. But be wary of unscrupulous businesses pouring sand and gravel cement at the bottom of the sound body to increase the weight to deceive consumers.
The third is to knock on the box body: use the knuckles to knock on the top, bottom, left and right front and rear baffles of the box body. All sides of the box body emit a solid and slight crisp sound. It feels that the texture of the plate is hard and thick, and there are multiple reinforcement ribs inside. The box structure Reasonable and sturdy, with a variety of sound insulation and anti-standing wave measures and other effects. This kind of cabinet is costly and difficult to process, so there are few counterfeit and inferior products. If you hit the box with the knuckles to make a "puff, puff" empty 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 reinforcing ribs to maintain the interior, which leads to the formation of a large number of diffuse reflections and standing waves in the box. Buying this kind of speakers will never get a good playback effect.
The fourth is to recognize the nameplate: really good speakers have a well-made gold-plated or chrome-plated nameplate mark, and the nameplate generally has a distinctive trademark, company, name, place of origin, and corresponding indicators. The imported boxes are in English such as: Made in xxx or Manufacture and corresponding trademarks, speaker indicators, etc. If there is only Design... (XX design) or vaguely marked with only one country name, even apart from a few basic indicators that are simple and extremely imprecise, neither the origin nor the manufacturer can be seen, and there is no trademark or registration mark. . Most of these Sanwu products are suspected of being counterfeit or inferior. Brand-name speakers attach great importance to brand image and corporate reputation, so the nameplate marks are very standardized and exquisite, and various indicators, corporate names, and origins are all available. Some nameplates are even made of thin metal plated with 24K real gold, and the fonts on them have a sense of unevenness. The product not only has the factory date, production serial number, and even the matching serial number and the ID card in the box. For this kind of speakers, as long as the price is reasonable, they can generally be used with confidence.
