The Importance of Subwoofers

                                      The Importance of Subwoofers

It is basically impossible for a pair of speakers to reproduce all these frequency bands without distortion, and the cost is very high. The more bass, the larger the volume of the speakers, the more difficult it is to adjust the sound, and the low frequency is less The cost of some speakers is also lower, and the sound is easy to make. When listening to music, most of the music does not need very low low frequency. There are bookshelf boxes, satellite boxes, etc., big and small, and there are many sizes.

Generally, people who are familiar with audio, just look at the speaker diameter and the size of the cabinet, can roughly understand how low the low frequency the pair of speakers can play, even if the low frequency dives, such as 50Hz, 60Hz for the bookshelf box, 25Hz, 30Hz for the floor box wait.

Don't be too superstitious about the parameters. Except for those top brands in the world who are very strict, the parameters marked on most cheap speakers are inaccurate and have no practical significance. In the end, you have to feel it with your ears.

If the floor-standing box is too big, it is not easy to place, and the low frequency of the bookshelf box is not enough, so some people think of adding an independent large-diameter speaker to play low-frequency sound, which can also supplement the problem of insufficient bass. Later, with more experience, I found that the main speaker can even be the size of a fist, and the subwoofer can also achieve the effect of a large speaker. Not only is the cost relatively low, but it is also easier to place and more beautiful.

Although adding a subwoofer can make up for the low frequency of the bookshelf box or satellite box, it is very difficult to achieve a good effect. Therefore, in the HIFI circle, most people do not add a subwoofer. Use bookshelf boxes for acoustic and string music, and use floor boxes for symphony music.

If the requirements are not very high, this method of adding a subwoofer is very marketable. For example, you can have a set of multimedia audio for a computer for one or two hundred. People think that it is very cost-effective to have an extra subwoofer. It is not only cheap, but also has more bass, but they do not know that the subwoofer effect of this kind of computer speakers is not right, and experienced people will buy bookshelf speakers instead.

The Importance of Subwoofers in Home Theater

It is not a big problem to listen to music without a subwoofer. The main reason is that the frequency range is limited. Except for symphony and disco music that require very low low frequency, most music bookshelf boxes are enough, as long as it is not intentional. If you want to pursue the majestic effect of symphony or disco, even if the low frequency of the speaker is less, it doesn't matter much, as long as the overall sound is good.

But the sound effects of movies are different. There are many natural sounds in movies, such as landslides, lightning and thunder, impact sounds, etc., and some exaggerated sounds, such as the sound of fists hitting, if it is real In the live scene, this kind of sound will not be too loud, and there will not be too much low frequency, but for artistic expression, the sound of fists is generally exaggerated in the later stage, so a lot of good low frequency is also required. In addition, the background music of the movie, whether it is symphony or ordinary music, requires a relatively strong low frequency to better express the atmosphere and scenes of the movie plot.

It is precisely because the low-frequency content in movie sound effects is very rich, not only requires a better low-frequency dive, but also requires a good sense of strength and speed. Some more demanding users still want to pursue the sense of shock absorption The effect is not only for the ears, but also for the body. For example, when the landslides and the ground crack, the sofa and the floor are shaking at the same time. These low-frequency effects are difficult to express even with the best floor-standing boxes, let alone ordinary bookshelf boxes. up.

Therefore, the subwoofer is very important in the home theater, not only to supplement the low frequency, but also to pursue the low frequency energy, speed, strength, etc. Real, send and receive freely without sloppy.
