How to synthetically evaluate the sound quality of loudspeakers?
Different styles and models of loudspeakers have their own advantages and disadvantages, and the prices vary greatly. Take the high-pitched loudspeaker as an example. Whatever price and level of the high-pitched loudspeaker is chosen, the sound quality can be used as the criterion to make the right purchase choice. We can make a comprehensive evaluation of the sound quality from the following aspects.
1. Testing the quality of low frequency
The low frequencies produced by inferior tweeters can be deafening, but they are totally bloated and thicker, lacking the sense of hierarchy and firmness. The low frequency of a good loudspeaker
should be clean and clear, with distinct layers, without mud and water, and without any loss of soul. Even the bass of various low frequency instruments such as drums, bass guitars and pianos can be easily distinguished. So don't be easily deceived by the low-frequency sense of measurement, inferior low-frequency is not as comfortable as clean sound.
2. Testing IF voices
Voices are the most frequently heard voices. It's not difficult to detect their merits and demerits. Pay attention to whether they have unusual nasal sounds or the feeling of being muzzled. The "box sound" of some high-pitched speakers can also interfere with the IF greatly, making the sound of this frequency band blurred. Intermediate frequency tone dyeing is more serious than other frequency tone dyeing, because most of the audible voice rate, or frequency is concentrated in the intermediate frequency range. This is an obstacle to replay almost all kinds of music.
3. Testing flexibility at high frequencies
Poor high frequencies are shrill, cracking headaches. In extreme cases, the sound of violin or soprano becomes the sharp noise of brakes. Similarly, different instrumental music in the treble produces different textures, and the treble of a good loudspeaker can be distinguished. The superior level of high frequency can even distinguish two different rhymes played by different wood in different years. The easiest thing to master is that the high pitch of a good speaker is not audible and daunting, the pore is erected, and it will not make people listen more and more tired. It is still easy to hear at the top but will not produce muted sound.
