I believe that consumers choose to modify car audio systems for a better listening experience, but there are some car owners who are not satisfied with the effect after modifying the audio system. For example, it sounds okay in the driver's seat, but the passenger seat feels uncomfortable and only feels a sound on the right side, overall the listening experience is not good.
The car owner is pursuing an atmospheric sound effect, which requires a skilled tuning technician who is good at tuning, and can also be matched with other speakers on the rear door. The current configuration is quite messy. The car mainly compares the sound effect with the original car, but those are all designed by hundreds of designers for a single car. Its design and tuning are not something we can find in the market. Even if the same equipment is moved to different cars, the effect will be completely different. To achieve the desired audio effect for car owners, it is necessary to have a professional sound engineer to produce the sound you want. And the matching of equipment needs to be changed according to the situation.
The specific solution is:
1. The downloaded popular songs WAV and FLAC are ultimately compressed and cannot match the sound quality of CDs.
2. The processor h800+c800 can set several curves, which can be adjusted and set according to your downloaded music listening experience, so that you can switch.
3. Suggest actively adjusting the frequency divider to be more detailed.
Changing the subwoofer makes the front row sound comfortable, but the back row feels annoyed. What should I do?
The whole car's front and rear doors were equipped with a set of speakers, and after adding a DSP amplifier, I felt that the bass was not enough. I also added a 12 inch bass box, but found that it took up too much space. Later, I found that several spare tire subwoofers were good, and I tried listening to them one by one and chose the Aiwei spare tire subwoofer. It can be considered as one of the several active spare tire subwoofers that I have heard with better inner sound quality! After more than a week of debugging (in different environments) after installation, a satisfactory solution was finally developed. Sitting in the front row, listening to the bass was done by blocking it from the front, but the back row couldn't accommodate people. The noise in the back row was annoying. Later, the bass volume was turned down and the back row stopped making noise, but the front row couldn't hear it! I tried to start from the frequency again and cut the frequency to 35Hz on the DSP. The back row still feels noisy. The previous 12 inch bass can be adjusted to the front row to listen to heavy bass, while the back row sounds light but not as deep as the front row. However, the seats in the back row can accommodate people, which can be annoying.
May I ask which expert can help answer what the reason is? Is it due to equipment issues or is it because the frequency of the DSP's bass is not adjusted correctly! I set the front door on the DSP to full frequency high cut 50 Hz, the rear door speaker to high cut 150 Hz, and the subwoofer started to set it to 70 Hz. Later, when I found it noisy, I switched it to 35 Hz with a slope of 12dB. The front volume was -3dB, and the rear volume was -15dB. The subwoofer volume was turned on.
Su30-2: The ideal performance of subwoofer is low, quiet, and the overall sound is mellow. Your system has added a DSP, which may be a high level connection, greatly reducing the signal source, which is also one of the reasons for the noisy sound. Is your 35Hz cutoff frequency an upper cutoff frequency or a lower cutoff frequency when the conventional subwoofer range is between 20 and 120? Generally, in order to prevent low-frequency noise, frequencies below 35Hz may be cut off to obtain a clean ultra-low. The uplink cutoff frequency is generally between 63-80 depending on the specific situation. Due to the fact that the sound pressure difference is related to distance and space, it is normal for the rear seats to have a slightly higher bass sensation. BMW does the best in this regard, even if its performance is not very good, its bass is the most evenly distributed in space.
Does the phase meter test the front and rear door speakers with the same phase, but the treble phase is different?
The front door speaker is from Morramas Dance, and the frequency divider is also wired according to the instructions. The rear door is a coaxial speaker, and now only the tweeter is in the reverse direction, while the others are all in the forward direction.
Haozi: Mashiwu wired the frequency divider, and during phase testing, it was normal for the two tweeters to reverse phase. This is how the speaker was designed for the frequency divider, so you don't have to worry.
As for your little cannon question, first of all, what type of songs do you listen to? Forget DJ and big news. The ultra-thin bass of the seat cannot achieve ultra-low frequencies and sound pressure below 40Hz due to space design issues. If it is considered as compensation for low-frequency volume and intensity, listening to ordinary songs is similar. As for loose, not sturdy, and lacking intensity, this is related to debugging issues.
Firstly, turn off the ultra-thin bass to see if the 6.5 inch mid bass of Mars Dance has any strength or volume. If so, adjust the crossover point, level, and phase of the ultra-thin bass.
Secondly, if the bass in Mars dance lacks strength and volume, it can be very troublesome. No matter how thin the bass is adjusted, it cannot produce good bass effects. Because we need to understand the frequency response structure of a piece of music, the fundamental frequency of a bass drum resonates downwards from 200Hz. The effectiveness of a bass drum depends not only on the bass unit, but also on the performance of the medium and low frequencies, which complement each other.
Huaihua Dejun: Whether treble should be reversed depends on the crossover network. Common second-order division requires high pitch reverse. At this point, using a phase meter for testing, the treble is inverted, but the actual sound reception is normal! Because there is a 180 degree phase difference in second-order frequency division, the inversion of the treble just makes up for this difference. A deeper exploration reveals that the difference between high pitched and mid to low pitched is not just between 0 and 180 degrees Different frequency division points? The slope and distance difference will all affect this phase. All phase differences serve a more balanced and natural connection.
