A look at the craft: A look at the craft is to judge the quality from the first impression of the appearance of the speaker: the speakers made of natural logs are of course the best, and there are many world-famous supreme speakers, including Italy's Chario and Guarneri.
Pay tribute, etc. But such a good box will never be as popular as the ubiquitous "Rejoice" shampoo because of environmental protection, lack of resources, technical difficulty and long time, and the price will certainly not be low.
Therefore, the common speakers are decorated with a thin layer of wood veneer on the surface of MDF medium density fiberboard: solid wood veneer, beautifully decorated speakers, especially rare wood veneers such as rosewood, sparrow eye, pear wood, walnut, Zhennan and red oak, which have 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 can only be regarded as low-grade goods at best.
However, although the box decorated with this kind of paper veneer looks extreme, it is more important to pay attention to whether the sewing behind the box and the digging process of the horn installation position are accurate.
Fake and shoddy products generally don't pay attention to these details, and they can be judged correctly with a little care.
Second, weighing: Good speakers mostly use 18 ~ 25mm high-quality MDF particle board, while high-end flagship speakers use overweight solid wood such as rosewood 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.
The third is to knock on the box: knock on the front, back, left and right baffles of the box with your knuckles, and all sides of the box will be heavy and slightly brittle. It feels that the plate is hard and thick, supported by many reinforcing ribs inside, the box structure is reasonable and firm, and various sound insulation and standing wave prevention measures are adopted.
This kind of box is expensive and difficult, 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 is no sound absorption material or reinforcement 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.
The fourth is to identify the nameplate: really good speakers have quick and excellent gold-plated or chrome-plated nameplate signs, and nameplates are generally engraved with distinctive trademarks, companies, names, places of origin and corresponding indicators.
Imported boxes are in English, such as Made.
exist
Xxx or manufacturer and corresponding trademarks, speaker indicators, etc.
If there is only Designin(XX design) or only a country name is vaguely marked, even except for 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-name speakers attach great importance to brand image and corporate visibility, so the attached nameplate logo is very standardized and exquisite, with all indicators, corporate names and places of origin available.
Some nameplates are even thin metal plated with 24K real gold, and the fonts on them are still uneven.
The product not only has the factory date, production serial number, but also the matching serial number and packaging box.
For this kind of speakers, as long as the price is reasonable, you can generally choose with confidence.
