Sound quality factors for speakers

Any speaker has its strengths and weaknesses, in a limited budget, low-cost speakers easy to attract the eye, but it is not easy to get quality effect, but for any price level and the level of speakers, are required to have a certain reference standards or direction, simply to say that we can test the quality of the speakers from four aspects:
1. test
The low frequency produced by the inferior speakers can be a hearing loss, but it is a loose, thick, thick, lack of sense of hierarchy and strong sense of. Good low frequency should be bright, clean, structured, not dragging its feet, even all low frequency musical instruments such as the size of the drums, bass guitar and Piano bass can easily distinguish. So do not easily deceived by the low frequency quantity feeling inferior, low voice as clean natural comfortable.
2. test if the voice did vocals are most commonly heard voice, the pros and cons, actually not difficult to perceive that pay attention to voice is unusual nasal or sipping a vocal mouth feeling. Some speakers of the "box" will also greatly interfere with the if, so that the voice of the frequency of the band. If it is more serious than the other frequency sounds, most of the audio frequency, or the frequency of the music is concentrated in the intermediate frequency range, which is a barrier to the music.
3. testing high frequency flexible sense < br / > inferior tweeter is shrieked in ear, listen to head a splitting headache and in extreme cases the elegant violin or soprano bel into sharp noise. Similarly, the high pitch of the different instruments to produce a different texture, a good pitch is able to distinguish. The high frequency and the quality of the first level can be a very good one. Most likely to grasp the key is good treble is not a more listen to more tired, is smooth and level, high to the highest point is still easy to hear.
4. test of the high volume and sound field junction like
some speakers in the bass performance is stable, but the volume is raised to a certain index will be distorted, or "beat", there are a variety of non recording music signal. In particular, if the string is one of the favorite music, you must pass this pass. Conform to the standard of the speaker in a certain extent do voice box, creating a clear sound field and the like, showing different instruments of the equinoxes position and texture, there are plenty of diffusion even growth, width and height but the degree of spatial audio. < br / > high-quality speaker broadcast voice can appear plump musical sense and sense of air, and note the bounce, vocal and instrumental sound not entangled, showing whole carefully ordered the audio and video. Listen to the ear is not tired for a long time
