So, what are the main differences between HiFi speakers, AV speakers, and monitor speakers? Below I will analyze the characteristics of each of them for you.
1, clear and turbid
The sound of HiFi speakers is clear, paying attention to the taste of music, focusing on the tranquility of the background and highlighting the music. Therefore, it feels like the flow of clear water through the heart, like a stream and a lake; the sound of an AV speaker is atmospheric, paying attention to the portrayal of the picture, paying attention to The creation of the scene, so it feels like a feeling of turmoil, like a river and the sea.
2, details and momentum
HiFi speakers pay attention to music details. Because I use HiFi speakers to listen to music, I often enjoy tea, feel the music in detail, mix with the singer and the instrument, the better the speaker, the performance. The deeper the characteristics, skills and character of the person, such as the author does not like Mutter, because her violin string feels too much, too feminine, on the contrary, the performance of Head & Shoulders is just right. Although some HiFi speakers perform well in music, they are still worse than AV speakers. The details will definitely affect the momentum; AV speakers focus on the creation of character dialogue and big scenes, because I am using AV speakers. When I was in the movie, I often felt with my family that I felt the grandeur of the scene and the dialogue. It was just a scene. HiFi speakers are not as good as AV speakers. In addition, when watching movies, the main attention is on the screen, which is naturally ignored. The details of the sound, the role of the AV speaker is to use the grand sound effect to set off the picture, naturally neglect the details, this is the difference between HiFi speakers and AV speakers, which is the idea of ​​these two speakers in the design different.
3, sound field
The sound effect created by the HiFi speaker is on the front side and deep in the depth. I saw a lot of photos in the forum: the speaker is parallel to the display, and the back is only against the wall. I don’t know, the sound field is flat, there is no depth, the natural character The position of the instrument is poor, and there will be a feeling of getting out of the box. My two pairs of speakers, one pair on both sides of the computer, the other pair is in front of the computer desk, about 50CM away from the computer screen, and the sound field falls on the computer screen. In order to reflect the layering of the characters and the bands, friends who have already got the bookshelf on the bookshelf may wish to try: move the box half a meter away, listen to the sound around 1.5-2M from the box, see what it feels, if you hear Still flat, then your speakers or offensive and defensive is not enough.
The sound effect of the AV speaker is surround, and its front sound field is not deep, so it can be seen that the front position of the AV speaker is parallel to the display. This kind of speaker's image is not as good as the HiFi speaker, because it can create a grand scene. In order to make up, the center speaker is added to highlight the sound field of the character and make up for the lack of the intermediate image. In order to increase the sound field momentum, the subwoofer is usually configured, so the difference in the sound field is the biggest difference between the two speakers.
Monitor speakers generally refer to all speakers used to monitor recording at any stage of recording and post-recording. Strictly speaking, the monitor speakers should be widely recognized in application and monitor recordings and made a series of improvements to the special requirements of recording broadcast engineers. It must achieve the following basic characteristics:
1. Expand the belt exhibition. For large monitors, the minimum acceptable is 40-16KHZ (+-3db). The small monitor speakers are only flat in the passband, but allow the low frequency limit to be slightly increased.
2. Uniform response in the frontal corner. The bandwidth described in the first item should be within the +-30 degree horizontal beamwidth and the +-15 degree vertical beamwidth, both of which are uniform with respect to the forward axis.
3. Controllable power response. The DI value of the system in the range of 250HZ-8KHZ should be such that the deviation does not exceed +-3db.
4. The correct time domain response. The system group delay should meet the Blauert&Law standard.
5. The correct stereo image. If the monitor speakers do not have a horizontally symmetrical mirror, separate left and right speakers can be used to achieve a symmetrical listening geometry.
6. Good impedance characteristics. The DC resistance of the system should be no less than 80% of the rated impedance and the phase should not exceed +-60 degrees.
7. The sound level has a lower distortion during normal operation. The system should be able to control the sound source to have low audible distortion.
Therefore, it is very difficult to achieve the above requirements. Those comrades who open their mouths to monitor the speakers should not talk about the monitor speakers. In most cases, the sound of these monitors is not very good, and these speakers are very environmentally demanding, and some require embedding in the wall to meet the requirements. The sounds played by these speakers are usually straightforward and not aesthetic. Don't assume that you can simulate the scene with an expensive monitor speaker system. What people hear in the concert hall is the sound with longer reverberation, and what is heard in the monitor is the sound with less reverberation. Only the recording engineer knows how to adjust the recording and PA parameters with the sound heard from the monitor speakers. For our ordinary audiophiles, the tools used by this recording engineer are too expensive and the application is wrong. So don't think that if you bring the monitor word, you can use it as a senior home speaker.
