Infinity has ten units. The A-pillar is the high-pitched sound in the front row, the door is the low-pitched sound, and there is a group of center units above the central control. There is a treble on the back and a bass on the bottom. There is also a subwoofer on the right side of the trunk. As a compact car, both the point and the power are enough.
I've been driving this car for several days, so let me share my feelings with you.
Functional articles
First, the sound and the car have a high degree of cooperation.
Look at the treble on the A-pillar of this car. The highlight is the position reserved for the treble of Infinity. Unlike the door panel, this treble will be closer to the horizontal position of the human ear, so the treble we get will be purer.
if there is no central design, when we listen to music, our voices will be biased towards the direction of the car door. Therefore, the center position will play a great role in the localization of sound.
The high and low bass units with separate rear doors can also take care of the rear seats.
the subwoofer is responsible for spreading low-frequency energy all over the car. I think the crossover point is still relatively low.
the sound is half in the unit and half in the tuning. The selection of image points, the grasp of balance and the handling of frequency division need not only the careful design of audio manufacturers, but also the cooperation of car manufacturers. I did see this on this Lexus 3+, which is very rare.
Second, the multimedia part is good
When you enter the multimedia homepage, what you see is a streaming media player, which can directly select the leaderboard, style, language and singer, much like QQ music and Netease cloud music that we usually use. Just say what you want to listen to directly through the car voice, and my experience music library is still very complete.
Third, the function of Clar-Fi is simple and effective
Listening to streaming music is nothing more than Mp3 and AAC. It must be in a compressed format and cannot be lossless. Clar-Fi can identify the current music format, and compensate some missing information, especially high-frequency information, through algorithms. The feeling I experience is really adaptive. The worse the sound quality, the more compensation I get, and the better the sound quality, the less compensation I get from Clar-fi. However, my suggestion is that if you really love music, don't bother. Put your favorite lossless music in a USB flash drive and the sound quality will be much better. At this time, I suggest turning off the function of Clar-Fi and enjoying the original music.
therefore, my suggestion is: first, use USB flash drive to lossless music; second, use car streaming media to open Clar-Fi to play music; second, use mobile phone Bluetooth to play music. Some cars can't hear the difference between Bluetooth and USB, but this Infinity can really hear the difference in sound quality, so a good sound source is very important for this stereo.
fourth, Logic7 widens the sound field space by surround sound
After turning on Harman Logic7 function, you will instantly feel surrounded, and the depth of sound and the width of low frequency will increase. This function makes the sound effect heard by everyone in the car more unified, so why not sacrifice a little sense of positioning to get the satisfaction of the whole car? I tested the frequency response, and the sound curve after opening Logic7 was more optimized. However, I have tried classical music, and it is really not suitable for opening the function of Logic7, because there are a lot of spatial components in classical music, and Logic7 also creates a sense of space, which is difficult to agree. On the other hand, I dare not listen to classical music in many cars, because classical music still requires high resolution and dynamics, and this set of Infinity classical music is audible.
5. It can change the positioning of sound at will through the touch screen. A more effective function is the seat optimization mode. You can choose whether the front row is better, the back row is better or the whole car is average, so if there are any important people sitting in the back row, such as parents-in-law, you may wish to take care of them.
Test article
The frequency curve data of this car can be obtained through frequency sweep test
53Hz-17.8kHz (+-8dB)
I have tested more than 2 cars one after another, and all of them use (+-)8dB as the reference standard. Because the data of (+-) 6dB and (+-)5dB obtained by many cars are terrible, they can no longer be related to our ears.
We can get (+-)5dB frequency response data for this car's stereo, which means we can improve the sound reference standard of this car
12Hz-16.8kHz(+-5dB)
What is worth mentioning is the high frequency response of this car, which can be extended from 2kHz to 18kHz. Many car stereos will drop sharply after 15kHz, and this car will also have attenuation, but it belongs to slow drop.
Of course, there are some minor problems. This car has a small peak at 1.kHz, but it is not very sharp.
there is a shelf lift below p>4Hz, which is of course to resist the noise of the engine. There are some vibrating elements below 5Hz, but I think it's okay, because there are fewer elements below 4Hz in pop music, and the human ear at 5Hz is not so sensitive. I have tested some other cars with brand stereos, and the low-frequency * * * vibration appears at 1Hz, which is more uncomfortable. Many of the chest * * * sounds of drums, Bass and male voices we hear are near this frequency, and this frequency * * * vibration has a great impact on the low-frequency clarity.
this is due to the chassis technology and the grasp of driving texture of the lectra 3+.
EQ part has three-frequency adjustment of high, medium and low
The low frequency is adjusted below 2Hz, and the shelf is lifted or attenuated. My suggestion is not to mention it again, because the low frequency of this car itself is slightly higher, unless you have a long-term engine of 3 rpm, you can mention it a little. I don't recommend health either, because after all, these upgrades are really useful for resisting engine noise and road noise.
the intermediate frequency is adjusted around 8Hz, and the bandwidth is wide. This part of the frequency curve is greatly affected by the position, so it is not recommended to move, that is, it is possible for the driver to move a little, and passengers can feel a large piece.
If the high frequency is adjusted above 5KHz, the shelf will be raised or attenuated. My suggestion is that friends who don't like too many high tones can drop it. It is not recommended to mention it, because the high frequency of this car is really natural, and even a little more will destroy its original sound system.
Experience
Taken together, Infinity car audio is characterized by high fidelity, clear sound, good high-frequency extension, sound field setting of Logic7 is effective and durable, and Clar-Fi function is effective and intelligent.
I didn't turn on the stereo for a while when I first drove this car, which is also my habit. I need to listen to the noise of the car first. Lectra 3+ Performance Suite is a compact four-wheel drive small steel gun, with an acceleration time of 5.9 seconds per 1 kilometers, superior grip, and a feeling of flying close to the ground when stepping on the accelerator. Under this positioning, there is a lot of road feeling, and road noise will also be introduced into the car. When the sports mode or track mode is turned on, the engine speed will immediately increase to 3 rpm, and the restlessness will follow, which is exactly the fun of this car.
at first, I was worried about the control ability of the stereo, but in fact Infinity didn't use any tricks, just super high fidelity and some low-frequency supplements. But it is precisely this that ensures the sound quality and complements the performance of Lectra 3+, so this is not the unilateral success of Infinity and Lectra, but the combined strength and chemical effect. Of course, the most important point is that Infinity and Lectra are doing well.
The brand stereos of some cars I tested before were only equipped on the top models, and the Lexus was better. There are three models and two models of Lexus 3 and Lexus 3+ respectively equipped with this set of stereos, so all the five middle and high models are equipped. Friends who like Lexus may wish to pay attention to it.
this combination of good car and good voice is not bad!
