If you want to buy a good audio system, there are many factors to consider, such as the listening environment (computer desktop, living room); Is the function a home theater or playing pure music; If it's music, what type of music should I listen to (classical, modern, piano, symphony, pop, rock, etc.); Budget scope; Requirements for the appearance style of speakers; It's really not easy to choose a satisfactory set of speakers for what kind of signal source, etc.
If only considering sound quality, how to choose speakers with good sound quality? Firstly, the sound quality is not as good as Zui, only better, what suits you is a good sound quality speaker. Generally speaking, 'high fidelity' is a good sound quality. The key is to choose a speaker. The basic point of Zui is to choose a large caliber subwoofer as much as possible. If you want to listen, you can listen to a high pitched speaker.
Due to the three principles of true reproduction of sound:
The speaker has a wide frequency range and is flat. It not only refers to the axial frequency range in the traditional sense, but also includes a frequency range where the sound power is uniform within a certain radiation angle, indicating that the speaker system has good directionality.
Dynamic range (the range of sound from the most subtle to the most vivid), all modern speakers compress the recovery of dynamic range rather than reproducing it completely realistically. Maximizing the dynamic range as much as possible is an important indicator for measuring high fidelity speakers.
The sound quality is natural and realistic, and the lower the distortion, the better, especially under high noise and power.
These three aspects are directly related to the performance of sound, and a properly designed speaker system, regardless of size, does not have a significant difference between the mid to high frequency bands. The difference is mainly in the low frequency range, and what is not easy to do well is also the low frequency extension. A good low frequency is directly proportional to the volume of air that can be exchanged per second in a speaker system, known as volumetric velocity, which drives more air per unit time to achieve better low frequencies. This is the principle of physical acoustics. Large diameter speakers have a large effective vibration radiation area, making it easy to drive large volumes of air and reproduce low frequencies. Therefore, the most reliable bass method is to choose a large diameter bass speaker system as much as possible. (It is also possible to obtain the same vibration area as a large-diameter speaker by working in series and parallel with several small-diameter subwoofers, such as two 8-inch subwoofers with a vibration area equivalent to 11.3 inches of bass.)
Of course, a large aperture speaker system does not necessarily mean that its sound is good. The low frequency of a large aperture speaker system is difficult to design well. If the bass design is not good, the control is poor, and it is cloudy. Therefore, the correct design of a large aperture speaker system lays a solid foundation for the system's good sound quality. Usually, large caliber subwoofers with good sound quality are very expensive, and experts often say that 'bass is very expensive'.
But it can be certain that a small diameter speaker will have poor bass because it cannot exchange a large amount of air in a short period of time. To exchange a reasonable and maximum volume of air, a relatively long stroke is required, and most long stroke small diameter speakers often have various distortions. Many small speakers, by filtering out bass, make hearing cleaner, and the mid-range sound quality may be better, but they cannot have huge bass, especially the extension and dynamics of low frequencies.
In addition to large caliber subwoofers, good low-frequency playback also requires a large box. Why? For example, a rigid closed small box, the air inside is equivalent to an air cushion, it has a reactive force, blowing or sucking, cannot suck, the smaller the box, the more difficult it is, so to exchange a larger volume of air, a larger box is needed to cooperate with it. Therefore, the enclosure volume of professional music monitoring speakers ranges from 50 liters to 150 liters, and the diameter of a single subwoofer exceeds 10 inches.
Speaker, if the speaker is not large and the box is not large, do not expect to produce particularly good bass. It may be better than a subwoofer of the same caliber, but it is not on the same level as a large subwoofer. Without good bass and low frequencies, the probability of the entire speaker having good sound quality is also very small.
Of course, good sound quality is also related to the material quality of the speaker and the frequency separation of the speaker system. Different quality standards are reasonable for both manufacturers and enthusiasts, and can be discussed in the future. One thing is certain: a properly designed multi-channel crossover speaker system often produces better sound.
In addition, small aperture speakers are also good. There are many types of small aperture speakers, some are particularly suitable for playing language, some are suitable for playing near-field music, and some are suitable for playing specific content. Depending on the type and purpose, it may also be a suitable and good box. For example, the UK LS3/5A small monitoring speaker and the BBC designated monitoring speaker are representatives of the UK sound and are very good at language monitoring. Its five inch subwoofer measures a frequency of 70Hz-20Hz+4dB, with a resonant frequency of 40Hz and a Q value of 1.2. It is designed for compactness and convenience, sacrificing low frequency and efficiency. It has a low bass volume and low sensitivity, but it is a very good language monitoring speaker, especially suitable for broadcasting near-field monitoring.
