However, in such cases they also found the problem: every time the explosion sounds and heavy metal music are played, the regular bass will penetrate the room and cause vibration. At the same time, the originally comfortable people in the room (usually the wife and children of the user) will flee quickly because they can't stand the torture and vow to never step into the room again.
The final chapters of such "legends" always end in unpleasantness. Passionate users will slowly experience such emotional entanglements: perhaps such a "high-end" subwoofer is not as cool as it might seem. So the question is: "What does the subwoofer debug really mean?"
This question may be better to ask: “What does a subwoofer that has been successfully debugged sound like? How do you know if this subwoofer is debugged or not?†With the technology in recent years Progress, customers have raised this level to a new level. The emergence of equalizers and fine measuring equipment has pushed the home acoustic system to a new artistic level. Welcome to the home theater network shopping guide network!
Gone are the days of relying on the subjective listening of the human ear to adjust the position of the subwoofer, or to play the most familiar organ music to guess the bass frequency. We know that during the debugging process, although we will use the way of listening to the human ear, it is only used as an inspection of the live effect. Subjective listening can tell us whether the debugging is accurate, but far from using the device to be efficient, because the device can make precise measurements and analyze the problem, and finally help you solve the problem, which can't be done by subjective listening.
The primary goal of subwoofer debugging is to understand how the bass frequencies resonate in your room. These resonances will have a very special resonance effect in the room, and you will feel that the bloated bass comes from all directions, not from the sound field in front of you. This muddy, bloated, low-frequency effect distracts your attention from the precise positioning sound field formed by the front LCR. This effect often makes the subwoofer a sound source with a distinct positioning.
The performance of the subwoofer debugging depends on whether the listener can hear where the subwoofer is located. And a super bass with excellent performance is completely unseen, but at the same time all the acoustic images are perfectly presented, you will only feel the comfortable and pleasant bass flowing quietly throughout the room.
So what do you do to make the subwoofer emit such a wonderful bass? Here we give some suggestions as follows:
1) It is best to use a real-time spectrum analyzer instead of a sound pressure decibel to set the subwoofer level. It is important to know that professional tools can be more efficient and accurate.
2) The subwoofer phase needs to accurately adjust the delay time of the subwoofer;
3) The frequency response flatness of the subwoofer combines the function of the mechanical positioning and the equalizer.
Suppose you want to debug your subwoofer, you really need a lot of preparation. Because frankly, there are no other shortcuts to accurately reduce resonance. If you want to achieve the same effect by using an equalizer, you must use a high-resolution spectrum analyzer to very carefully debug each filter setting parameter, and even the most advanced automatic equalization system is difficult to achieve. effect. This requires a well-trained and experienced commissioning engineer to do this manually.
Although the debugging process is a bit more complicated, it is worth a try in order to hear the best bass. Perhaps after such debugging, the former beauty lady who has a fear of the bass may be willing to step into your home theater again, share the wonderful music with you or watch the latest blockbuster together.
