Has anyone ever bought a stereo that falls in love with HIFI? Tell me about it.

The cost performance is not bad. Be sure to look at it comprehensively when choosing the sound. Some people will pay more attention to the parameters of sound. Although sound parameters are very important for choosing a sound, they are not all. Although the parameters of different speakers are the same, the sound quality effect is quite different. The key point is to know how to look at the speaker material, speaker structure and frequency division number.

For example, high-pitched units can usually be divided into hard top and soft top. The hard top is made of aluminum alloy, titanium alloy and other light metals, cast or pressed with ultra-thin alloy, and then the surface is chemically treated. Its timbre is bright and thorough, with high resolution. Soft top is generally made of silk soft film, with delicate and soft tone and strong expressive force. For example, if the bass unit has a paper tray, it has the advantages of rigid-flexible combination, high internal damping and easy mixing with other materials. The timbre is naturally thick and the bass is full. The bullet-proof cloth basin (woven basin), because of its light weight and strong rigidity, can produce wider frequency response and lower distortion, can bear more power, has warm and natural sound, deep intermediate frequency, sharp low frequency and good transient response, and has excellent effect in playing large-scale dynamic music. The disadvantages are complex manufacturing process, high cost and poor performance when playing light music. And these are not visible from the parameters. Speakers like Opera don't have many features in parameters, but its coaxial unit positioning and resolution are better, and it is a quad-band speaker with better consistency in the whole frequency band. In addition, there is an 8-inch bass unit and a * * speaker, which makes the sense of low frequency more sufficient. When choosing a speaker, you must look at it comprehensively, not just one aspect, hoping to help you!
