There are a lot of domestic first-class speakers: Yindi, South Whale, Feile, Huivei, Suowei, electronic market speakers can be made to sound very good speakers (including the cheapest speakers).
It is worth mentioning the emergence of new domestic "Solvay" coaxial speakers, this speaker has the best sound and image positioning, because it is a collection of low-midrange and high-tone in a speaker (the British brand-name Tianlang speakers is this structure) sound phase distortion is very low, better than the general non-coaxial speakers, coaxial speakers to make the speaker, stereo and surround sound effect is far from being a good idea, and the speaker can be made in the same way. Stereo and surround sound effect is far superior to other speakers.
Sound quality of the speaker is good, mainly bass to be good, midrange and treble are generally easy to do very well, only the bass is the most difficult to make the subwoofer below 40HZ.
The key to the speaker is the size of the speaker to be large enough, the thickness of the plate to be good, the internal structure also has to pay attention to, the crossover is also very important, if the speaker does a good job, what brand of speakers installed on the excellent sound performance (need to be repeated with a few speakers to compare and contrast, debugging, but also with the same price of a few brand speakers to compare the effect).
