There are many domestic first-class speakers: Yindi, Nanjing, Feile, Hivi, Solway, and the speakers sold in the electronics market can all make speakers with very good sound (including the cheapest speakers).
It is worth mentioning the newly emerged domestic "Soway" coaxial speaker. This speaker has the best sound image positioning because it combines low, mid and high frequencies in one speaker (British brand Tian The sound phase distortion of the Lang speaker is very low, and its performance is better than that of ordinary non-coaxial speakers. The stereo and surround sound effects of speakers made of coaxial speakers are far better than other speakers.
The main reason for the good sound quality of the speakers is the good bass. It is generally easy to make the midrange and treble very well, but the bass is the most difficult to make a subwoofer below 40HZ.
The key to a speaker is that the size of the speaker should be large enough, the thickness of the board should be good, the internal structure should be careful, and the crossover is also very important. If the speaker is well made, any brand of speaker can be installed on it. Excellent sound performance (you need to use several speakers for repeated comparison and debugging, and you can also use several brands of speakers at the same price to compare the effects).
