This is the first step for buying speakers. You can hold the speaker with your hand to take a weight. Generally speaking, the heavier the weight of the speakers of the same grade, the better the quality. This method can be widely used to buy other audio products. The heavier the weight, indicating that the various materials of the speaker are authentic and there is no cutting material. Imagine that the speaker material is from the wood used to the speaker, the amplifier board, and the power supply. Do you think it might be able to post the music that can be sent out?  
 
2. Look at the appearance  
This is also an important step. First, you can see if the overall shape of the box is satisfied, and then take a closer look at the sticker layer of the speaker. There are obvious phenomena of foaming, scratching, and roughness. It is tight and neat, and you can remove the dustproof gauze on the front panel to carefully check the materials, materials, specifications of the high bass speakers and specifications from the instructions. Firm and tight and so on. Finally, you can see if the tight silk on the speaker is used in the inner hexagonal filament. This is a detail. Generally, the low -grade or counterfeit and shoddy products mostly use ordinary self -attack silk.  
 
3. Understand performance indicators  
First of all, pick a more famous speaker in the market. We are free to talk about the miscellaneous cards, because the performance indicators given in the manual must be all false, and it is not credible at all. Although the performance index data given in a brand speaker instructions, although we ca n’t fully believe it, some Dongdong cannot be completely unbelievable. It is still necessary to reference for the time when you buy. In addition to understanding the weight of the speaker, the size of the appearance, and whether the accessories are approximately equivalent to the nominal, you can also understand the nominal power, impedance, frequency ringing, distortion, dynamic range, etc. of the speaker. Exaggerate its words, and you should also understand whether the horn is an anti -magnetic speaker and so on.  
 
4. Listening is real  
When choosing a speaker, you can choose a few brands or different grades of brand speakers at the same time to audition. Because the sound of generally selling speakers is noisy, everyone has to raise ears. Of course, it is best to go to the speakers or agency stores in the audition room to buy, which can generally provide you with more comprehensive services, and its speaker quality is generally more authentic than some miscellaneous stores. In most where there is no such environmental condition, everyone can bring a music disc that they often listen to the audio audition. Which speakers are better, and they can generally do it in their hearts. Of course, if it is really countless in your heart, you can also go directly to the agency shop to pick the famous reputation in the market.
