I use hivi's box in the incomplete manual of notes for purchasing speakers. According to my own experience and the experience of watching others buy boxes, I would like to sum up two sentences here, which are not good enough to make the experts laugh. First of all, price is not the only criterion for purchasing high-quality speakers. What matters is the sound quality of the speaker. Although some speakers are not luxurious in appearance, the sound quality can achieve the same moving effect. What do you need a speaker for, listening to music? DVD？ Still playing CS? It is recommended to use 2. for those who listen to music, 4.1 or 2.1 for those who are difficult to locate games and 5.1 or 7.1 for watching DVDs. Of course, 2.1 can still be considered for lack of funds. You don't have to choose a wooden box speaker. Using wooden boxes is a symbol of high materials. Most speakers in hivi use wooden boxes, but not everyone can afford hivi, and not everyone likes hivi. Many innovative boxes are made of plastic boxes, which also achieve good results. It depends on what materials the boxes should be, but on the density of materials and the ability of anti-seismic. (Some speakers use the vibration of the box to form a unique sound dyeing to beautify the timbre.) This can be felt by hand at a high volume. You don't have to choose a high-power speaker. At present, some speakers in the market flaunt how high their power is. What power is as high as 4W and the frequency response range is from 2Hz to 2KHz? Don't buy speakers from those manufacturers, because these data are deceptive. (4W refers to peak power, which is meaningless, and 2Hz to 2KHz is simply nonsense.) There are more than enough speakers with rated power of 5W for a room of 2 square meters. A manufacturer who even falsifies the data cannot guarantee that the speakers will not be falsified. A speaker with a large caliber does not necessarily produce a good bass. Good bass has many factors, including strength, convergence speed, elasticity, diving and so on, and these factors are closely related to the material and design of the box. A big speaker can't explain anything. You don't have to choose a bulky speaker. Perhaps for the sake of style, when buying speakers, I like to choose the big ones. In fact, size is not the key, the key depends on weight. Imagine, in order to ensure sufficient sensitivity and excellent dynamic effect of the speaker unit, the super-thick density board to increase the strength of the box, the heavy metal radiator to strengthen the heat dissipation of the high-power amplifier, and the large transformer to realize strong power supply are all factors that increase the component. Therefore, whether it is large or small, it needs to have a certain weight. Those speakers with empty bellies and unstable foundations must not be carried home. (The innovative transformer is external, and the subwoofer may be light in weight, which is an exception.) In addition, it is also very important whether the speaker is antimagnetic, especially the satellite box must be antimagnetic, otherwise the display will be in trouble. Some friends say that the speaker will ring when the mobile phone comes to information, but this problem is not very serious, and it is not the key to measure the quality of the speaker. Because different power amplifier modules are used, whether the speaker will ring when the information comes is decided by the power amplifier module. Other data (sensitivity, distortion, signal-to-noise ratio, impedance, etc.) are meaningless. The key to a speaker is to look at the sound, not the data, not to mention the data will be falsified. If you choose a speaker and are ready to buy it, you should also pay attention to the following questions: remember to look at the seal when unpacking. The box seal of hivi Multimedia is a kind of tape that looks like long fibers. If you find transparent tape, you should be careful. In addition, the seal can't be affixed with two strips, so there must be something wrong. Some merchants open the bottom of the carton to hide their eyes and ears, and check the best bottom if conditions permit. Unpacking inspection: 1. Whether there are paint scratches on the box. Whether the accessories (foot pad, bracket, wire control, remote control, wire rod and converter, etc.) are complete, and there are obvious traces of human use (fingerprints on piano paint, dust on grooves) must not be taken, because it may be returned goods. 2。 2.1 Whether the wire control with wire control is normal or not, the main problem is that the left and right voices are not the same, and whether there is a sizzling sound when the volume knob rotates. 3。 2. The potentiometer (treble, bass, volume) is adjusted in a consistent way, and there is no sudden tightness and looseness. The potentiometer in hivi may be unsmooth, and the volume is adjusted step by step, so there will be no big and small, and there should be no noise. 4。 5.1 adjustment should also pay attention to whether the volume of each speaker is the same under the condition that the adjustment buttons are the same. 5。 If there is a dust cover, it is best to take it off. There is no problem on the surface of the unit. 6。 Turn on the sound, all units pronounce normally, and there is no obvious distortion. 4.1 5.1 Users had better check whether the surround effect is normal. It is best to ask for an invoice, and you can fill in the details of the warranty card. If there is a service conflict in the future, you can find 315 with the invoice. There are activities to give away disc gifts, understand clearly, and the watch was taken by JS. The paper box is relatively large, so it's best to carry it by two people, and then call TAXI, so don't crowd the bus.
