1. The quality of low frequency
The deafening low frequency produced by inferior speakers is the kind of sound that is bloated, bulky, lacking in grade and toughness. Good low frequency should be clean and clear, with a clear grade, and will not speak quickly, even if various low-frequency instruments such as big and small drums Bass, bass guitar and piano bass can be easily distinguished. So don't be easily deceived by the sense of volume of low-frequency, low-quality low-frequency is not as natural and comfortable as clean sound.
2. Mid-frequency vocals
The human voice is a sound that is often heard. It is not difficult to detect whether it is good or bad. Pay attention to whether the human voice has an unusual nasal sound or the feeling of being pursed. The "box sound" of some speakers can also interfere with the midrange, making the sound in this frequency band indistinct. IF sound staining is more serious than other frequencies. Most of the audible sound frequencies or music frequencies are concentrated in the IF range, which will hinder the playback of music.
3. High-frequency flexibility
The high-frequency squeaky sound of inferior speakers is piercing to the ear, which makes people have a splitting headache. Under bad conditions, the elegant violin or alto voice can be turned into sharp noise. Similarly, different instruments in the bass will produce different textures, and good bass can be distinguished. Even better or worse, the high frequency can even distinguish the different rhythms played by two different woods of different years. The key to easy control is that good bass will not make people more tired after listening. It is smooth and classy, and it can still be heard easily at high altitudes.
4. Low volume and sound field imaging
Some speakers are more stable at low volumes, but when the volume is raised to a certain index, they will distort, or "beat edge", showing various non-recording musical signals. Specifically, if orchestral music is one of the favorite types of music, you need to pass this level. A loudspeaker that complies with the specification can sound out of the box to a certain extent, creating a clear sound field and imaging, showing the split point position and texture of different instruments.
