's "Sound for You" audio evaluation, the first model rated s has finally been released - Wenjie m9.

We were confused about the scientificity and rationality of the test standards, because among the more than 20 models tested in the past, there were many traditional luxury car audio brands such as Bowers & Wilkinson, KEF, and Mark Levinson. Although the audio quality was extremely high, We were impressed, but the final rating didn't live up to their price tag.

Fortunately, the arrival of Wenjie m9 proves that the pursuit of audio design that "sounds good, looks good and is easy to use" is not just our opinion. We also look forward to more models bringing you more unforgettable music journeys.

This time, the model we tested is the 2024 pure electric version of Wenjie m9, equipped with Huawei Sound Superior series self-developed audio, with a total of 25 speakers, an output power of 2080w, and the car and machine version is harmonyos 4.0.0.105 (sp13log)

question Jie M9 is the first model to receive a basic score of 5.0 points since the test. Compared with other high-scoring models with 4.9 points, Wenjie M9 is superior in appearance.

The first thing is that each of the four doors is equipped with independent high, middle and low speakers. This configuration is unique among the current test models and can effectively ensure the consistency of listening for each passenger position.

Not only that, the surround speakers on the C-pillars on both sides also use high-mid frequency crossover, with two speakers arranged on each side, which is also the only one.

In order to bring a better audio vivid spatial audio experience, Wenjie m9 has arranged 4 sky channels on the top. They are located in the middle of the side beams on both sides of the front row, and corresponding to the upper part of the b-pillar. The

center console is equipped with a midrange and a tweeter.

The left side of the trunk is equipped with a subwoofer.

In addition, there are two headrest speakers on the main driver's side.

In the decoding test session, we first used the top three test files, which included an easter egg file with a hidden encoding format, a 7.1.4 file that exceeded the decoding specifications, and a master tape with an ultra-high sampling rate. After actual testing of

, Wenjie m9 can play the master file smoothly, and its decoding ability is evident, but the other two files cannot be played. Since this is just a stress test and does not have broad significance, the results will not be counted. During the

test, we repeatedly sampled the vehicle's main driver's seat and the "boss seat" on the right side of the second row. The ambient sound at the

test site is 44.7db. Insert the test music USB disk, play the pink noise source and sample directly in front of the steering wheel. Adjust the multimedia volume to increase the sampling volume to 70db, which is used as the test volume. (*This volume is the speaker sampling volume, which can give better performance to the speaker, but please do not use it while driving. It may affect your hearing in the long term and affect driving safety)

At the same time, we also recorded the test volume at the exterior rearview mirror. The ambient sound below is 65.0bb. (Currently not used as test data)

Let’s first look at the frequency response curve of the main driver’s seat:

In the promotional brochure of Wenjie m9, it was mentioned that this audio system can achieve an ultra-low dive of 20hz. I was skeptical about this at first. Attitude, but judging from the frequency response curve, the ultra-low frequency has reached a very high level in terms of response and intensity. The most intuitive feeling is that you can experience more "heartbeat" low frequencies.

Starting from the mid-range to the 12khz treble, Wenjie m9 shows extremely strong control. For such a large space and a relatively complex interior layout, the frequency response curve can be achieved at a sampling rate of 1/48 The nearly horizontal control is enough to show the foundation of Huawei Sound, and its speaker quality and spatial algorithm capabilities are evident.

is worth mentioning that under the same test conditions, the average decibel of this sampling reached 47.8db, which is currently the highest, which shows that its 2080w power amplifier is genuine.

Let’s take a look at the sound field positioning performance:

In terms of sound field positioning, Wenjie m9 is almost impeccable and very accurate. Whether it is horizontally or vertically, it can hit where you point. The only flaw is that due to the full The car has too many speakers, so the overall sound intensity package will be very strong, and even in places where there is no sound, there will be a slight sound.

There will be slightly more interference, especially in the lower rear part of the main driver's seat.

Finally, let’s take a look at the data sampled from the “boss seat” and compare it with the main driver’s seat:

It is no exaggeration to say that it is difficult to find out who is who in the two seats at a glance. For most models, it is difficult. The problem of high and low frequency out of sync, Wenjie m9 has achieved extremely uniformity, which is inseparable from the contribution of the multi-speaker layout.

But if you look carefully, there are slight differences between the two. For example, the subwoofer closer to the rear row makes the low frequency of the "boss seat" slightly richer, while the scattering ring of the center console gives the front row more treble support.

Let’s take a look at the sound field differences:

Driver sound field

Boss sound field

In terms of sound field positioning, the performance of the two positions can be described as “copy and paste”. This consistency once again makes us marvel at the tuning capabilities of Huawei Sound.

Here, we are also curious about the difference between the huawei sound superior series and the normal version of huawei sound. Therefore, we retrieved the previous question m7 test audio for comparison.

From the comparison, we can find that control is the strength of Huawei Sound. The two systems have almost equal control over the mids and highs, but it is obvious that the superior series has deeper penetration and the overall power of the amplifier is stronger. This is indeed in line with the requirements of the two systems. publicity.

Let’s take a look at the music ecology inside the car:

The music ecology of Wenjie m9 is extremely rich. In addition to downloading various music apps, the fully built “Huawei Music” platform is the correct way to open the Wenjie m9 audio system.

Since the Wenjie m7 test 3 months ago, "Huawei Music" has greatly improved both in quantity and quality of the music library, especially the spatial audio channel. The sound sources here all use audio vivid spatial audio technology, which can Make the most of your car's speakers.

It is worth mentioning that according to our rough statistics, the number of songs on this channel has roughly tripled in the past three months. In addition to the three fields of classical, jazz and natural sounds, a lot of pop music has also been added, which is more in line with User habits.

In terms of sound field settings, the biggest highlight of Wenjie m9 is its "adaptive" function. No matter where you sit in the car, the system will automatically adjust the output modes of all speakers, so that every seat is a "sweet spot" "Experience. The system of

is naturally inseparable from the contribution of multiple speakers, but what is more worth mentioning is that the settings of these sound fields are fully automatic, combined with multiple sensors in the car, to maximize the ease of use. Maybe it will be a trend in the future.

In terms of specific settings, Wenjie m9 can perform many micro-operations and preset many modes. However, according to our test results, unless you are a professional, please trust the engineers of Huawei Sound. They have provided Reached the best choice.

For users who like to use USB flash drives to listen to their personal collections, the Wenjie M9 interface is relatively easy to find, located in the suspension cabin at the lower part of the center console. But with Huawei Music, there is probably no use for USB drives.

The test of Wenjie m9 took two full days, and most of the time was spent on subjective testing, because it was really a kind of enjoyment. After listening to almost all the spatial audio tracks, we unanimously selected "My Motherland and Me" by the National Center for the Performing Arts Orchestra as the recommended track.

The opening applause, the majesty of the large-scale symphony, every note is intricate and deeply rooted in people's hearts. Every element of the entire track is stripped out and released again through the speakers to every corner of the car.

In fact, during the test, we also discovered a good thing, which is the privacy shield in the back row.

After this function is turned on, the back row seems to be surrounded by water, and the conversation seems to be encrypted. It is almost impossible to identify the conversation content in the back row in the front row, as if it is covered with a mosaic, effectively protecting privacy.
