As an entry-level cook, I always worry about choosing speakers. I am a player who likes to listen to music, like hifi sound quality, and like to study various audio devices. As early as in the student days, conditions did not allow, so I could only play with some earphones and mobile playback devices. There was not enough space in the school to place a large Del speaker, so earphones and MP3 players became the main equipment for listening to music and pursuing hifi at that time. At that time, some of the equipment used to play was not very high-end. After all, it was students who bought some music equipment they liked by saving food for several months. At that time, it was mainly equipment under 1000 yuan, Including mx365 akg k314p Gauss pp AKG K450 sonyE888, AKG K601 Baya Power DT990 and other earphones, while the players are mainly innovative MUVO2 FM innovative ZM and sony XK Meibo HD300 HD200 Airy and IFP series, which have played a lot, also because of the love of audio left by the students. Although they have been working now, they still have a great pursuit of sound quality. Since they are at home now and have a certain space, they prefer speakers to listen to music, Compared with earphones and other devices, speakers have more space. It is easier to listen to music without earphones. That is why I have played several types of speakers, from hundreds to thousands. I have played with the Sannuo N35G KRK RP5 before and the T200C currently in use. Each speaker has its own characteristics. The Sannuo N35G is a good equipment for my mill training due to its low-end positioning, The KRK RP5 is somewhat similar to the acoustic engine A2+in this trial experience, with the front design of the guide hole, while the T200C has a built-in Bluetooth function. Before the trial, take a group photo of the speaker I currently have..

For acoustic engine A2+, I checked the relevant parameters before the trial experience I also have some information about Sound Engine A2+. This is a small and compact HIFI speaker positioned on the desktop. The 2.75-inch woofer makes me a little worried about whether its bass elasticity and sense of volume are insufficient. The small volume of sound quality speakers want to achieve high sound quality, and its manufacturing process and selection of original parts are more complex and exquisite than the large volume speakers. The cost will be even higher. How about the performance of the acoustic engine A2+? I will have a detailed experience on the sound quality experience in the next chapter. The small volume speakers do a good job. The BOSE M2 I heard about is good. However, the price of sound engine A2+is not half of M2. I wonder if it is worth it.

The package of Sound Engine A2+is quite large, but I didn't find the white version or the black version on the package. At first, when I saw the front, I thought my version was black. When I opened the package, the white version was good. I prefer the white M2+, because many speakers are either wood color, or black. There are fewer white speakers. Here is a small defect, The white version or black version shall be indicated on the package.

When the acoustic engine A2+is opened, the speaker is wrapped in a cloth bag. The package looks very delicate and careful, including wire materials. The accessories of acoustic engine A2+include connecting wire materials, instructions, warranty cards, etc. There are not many things, but they are quite complete.

I like the white version very much when I open the acoustic engine A2+. The white version looks more concise. The acoustic engine A2+doesn't have much decoration, just the front horn and the bottom bracket fixing hole. The sound engine A2+adopts the piano paint baking process as a whole, and the whole speaker looks very smooth. As such, it has a great sense of weight and is easy to move and move. The connection cable of acoustic engine A2+adopts transparent branching design. In terms of sound input, the audio engine A2+adopts USB decoding input and public to public audio wire input mode. What needs to be mentioned here is that the USB input mode is decoded by the internal decoder, which can improve the audio.

The back of the acoustic engine A2+adopts a full black panel. From the back panel, it can be seen that the acoustic engine A2+is divided into the main box and the sub box design. This design mainly focuses on the multimedia speakers, while the acoustic engine A2+is the multimedia speakers that locate the desktop hifi. The acoustic engine A2+not only has a male to male speaker cable and USB audio input, but also supports the lotus head that is mostly used in power amplifiers. The lotus cable is not included in the standard configuration, so it needs to be configured separately.

The bottom of the acoustic engine A2+is provided with a speaker bracket hole. It can be fixed on the speaker bracket. Users who do not want to place it on the desktop can also be fixed on the bracket. In fact, I think that as a small volume hifi desktop speaker, I will spend more time on the desktop listening to music.

The transformer of acoustic engine A2+is designed outside the loudspeaker, which is very effective for reducing the volume of loudspeaker and improving the utilization rate of audio components. The conventional speakers are better equipped with high-power Huanniu, and the effect of using external transformers for acoustic engine A2+still needs to be understood after experience.

In order to show the small size of acoustic engine A2+, I compare my t200c speaker with acoustic engine A2+. It can be found that the volume of acoustic engine A2+is much smaller than t200c. Sound engine A2+is a compact volume, positioning desktop hifi speaker, which is more suitable for desktop listening. At the same time, it is also designed to position multimedia speakers. For users who have requirements for sound quality and need small size, sound engine A2+is very good, and I also have this demand. Why? Because the t200c on my desktop is usually too crowded, I always want to use a small volume speaker to replace my large volume speaker. At the same time, I'm afraid that the sound quality cannot be replaced. This experience of Sonic Engine A2+is a good opportunity for me to understand the sound quality of a small volume hifi speaker like Sonic Engine A2+.

The sound quality has always been a very subjective impression. I am an audio enthusiast. I am simply a fan. In my college years, I have played with countless audio devices, ranging from MP3 players to desktop CD decoders. He has his own opinion on hifi.

HIFI is the abbreviation of English High Fidelity, which originally means high fidelity. In fact, it is extremely similar to the original sound. When the sound is extremely similar to the original sound, the closer the original sound effect is, the more HIFI will be. Sound Engine A2+is a small desktop HIFI speaker that seeks to restore the original sound. How can the acoustic engine A2+achieve HIFI with such a small volume? Before the experience, I always held a skeptical attitude. Through my previous experience in playing audio devices, the smaller the size of speakers, the less good the performance in terms of large dynamic and large low-frequency sense, and the smaller the speakers, the better the performance will be in terms of vocals and small music. How does A2+perform? Now let's experience the sound quality effect of Sound Engine A2+in detail through several audition songs.

Before the experience, I think it is necessary to mention that Sound Engine A2+comes with a USB decoding audio output, which plays a certain role in improving the sound quality of the speakers. After connecting to the speakers through USB and playing after decoding, the listening sense has improved to a certain extent. This is also an unusual feature of Sound Engine A2+. This decoding is more suitable for situations where the integrated sound card is not very good, It is particularly important.

The USB decoding of Sound Engine A2+is of great significance to mobile devices, including notebook tablets. Through decoding, better sound can be obtained than before. In this regard, Sound Engine A2+is indeed a speaker for desktop HIFI, especially for mobile devices. This time, I mainly experience several different devices to understand the characteristics of the next sound engine A2+on different devices. First, I experience on the desktop, and output the audio experience through the USB decoding of the sound engine A2+.

First of all, famous audition songs such as Ferry, California Hotel, etc., which are often used for audition, were used.

"Ferry" is a song often used for audition. Of course, when playing audio, I don't know why so many people always use the Ferry and the California Hotel for audition. After listening for a long time, I gradually understand that Ferry and the California Hotel are two relatively comprehensive songs, especially in mid tone, as well as sound field dynamic analysis and positioning, These two songs can be distinguished very well. There are often fans who call the mezzo soprano the world. I have to say that there is a certain truth. The mezzo soprano part is connected up and down, and it is also the audio part we hear most often. Many parts of the ferry are shown in the middle and low frequencies.

The performance of acoustic engine A2+in the ferry is relatively standard. The so-called standard is standard. The main defect is that in the prelude drums, the performance of the sense of quantity and the depth of submergence are not enough. That's what I said earlier. The disadvantage of small low-frequency units is lack of the depth of large dynamic low-frequency sense, which does not give me the strong feeling of low-frequency shock, However, I was pleasantly surprised when Cai Qin's voice just came out. In terms of the reduction of the voice and the exquisite listening ability of the voice, Shengqing A2+performed very well. On the analysis of musical instruments, Sound Engine A2+also performs very well. The sense of orientation of each musical instrument is very strong, and it can accurately position in front, so that people can feel the voice in front. The left and right musical instruments are well transmitted from all directions. The overall sound field of Sound Engine A2+is not large, which is a feeling of being very close, and also conforms to the characteristics of near-field listening. In terms of sound crispness, acoustic engine A2+is particularly eye-catching, and the strings sound crisp and pleasant. On the whole, the music of Ferry is expressed on the sound engine A2+, which does not bring a sense of dynamic low-frequency shock, but has a strong hearing tolerance. The style of Sonic Engine A2+is not suitable for the music of Ferry. So I said that the performance is regular, the quality is good, but the style is different.

The performance of "California Hotel" can be said to give full play to the overall performance of "sound holding A2+". The clear applause, crisp and charming electric guitar sound, and cheering sound of the prelude can be heard in every detail, especially in the bass performance, which is also particularly eye-catching. The bass performance of California Hotel has changed from the decadent performance in the ferry, showing a very good dive and flexibility, This also makes me wonder why the low-frequency performance of the California Hotel is so good, but the drum beat and bass of the ferry are not shocking. After repeated listening and comparison, it is found that the main reason is that the drum beat sound is received too fast in the ferry, and the sound is stopped before the sense of volume is produced. The bass of the music of the California Hotel itself is sinking quickly, It doesn't need a strong sense of volume, so it has the feeling of fist to flesh, and the bass performance is relatively good. To sum up, the performance of bass lifting A2+is that it can dive to the right place with good elasticity, but a little less sense of volume. However, the advantage of A2+in the mid frequency vocal part is very obvious. The voice of the lead singer shows the vicissitudes of life very well. In terms of transient performance, A2+can be played in and out freely without too much sloppiness. The voice is crisp and neat, which is one of the reasons for strong hearing tolerance.

There is another song that I like very much and that I never get tired of listening to. Cai Qin's Song of Zhang San, the main theme of this song is cheerful and melodious, and the style of singing A2+is just in line with this song. Listening to a cheerful and melodious song, drinking a cup of coffee, a cup of red wine with the movie, and a cup of coffee with the music, this is a kind of enjoyment, a kind of life. Among the vocals, the sound engine A2+just shows Cai Qin's cheerful and melodious vocals. The style of Xiaoqingxin Music is very consistent with the positioning of this song. Sound engine A2+performs well in terms of vocal reproduction, light accompaniment and separation of various instruments. Demonstrate a strong sense of near field listening.

In terms of sound quality, finally, let's talk about the performance of popular songs. For popular songs, we will no longer play them with foobar2000, but use a more convenient Kuwo player and the highest APE audio format to listen to popular songs. Compared with test songs, we believe that popular songs are the choice of most people The style trend of SongEngine A2+is mainly oriented to vocal music, medium and high frequency small music that can be listened to, rather than rock songs such as DJs. It likes classical types, and Singers such as Liang Jingru and Xu Song who pay attention to vocal music performance are more suitable for SongEngine A2+.

First of all, let's try this year's hot little apple of the Chopsticks Brothers. The little apple is a bit like a DJ, but the performance of the sound engine A2+is not bad. The bass is flexible, musical and dynamic. It's also very good for desktop listening.

The theme song "The Road to Ordinary", which will never be seen in the future, also performs very well on the sound engine A2+. The sound engine A2+will not give you a big surprise, but in terms of overall quality and reduction, it makes you feel that you can't find any problems. In terms of hearing tolerance, it is very good, and it can make you listen for a long time, unlike many speakers, which are very shocking at the beginning, But listening for a while will be very tiring, which is the advantage of the little fresh style.

The performance of Jay Chou's songs, Xin Xiaoqi's taste and other popular songs is also very good. The vocal reproduction is quite good, and there are many musical instruments without confusion, Sound engine A2+performs well in pop music, and it is absolutely qualified as a desktop HIFI speaker. Desktop HIFI pays attention to near-field listening. The separation of voice and instrument is very good. However, it is more appropriate to give the dynamic music to a large speaker.

The sound quality performance of SongEngine A2+didn't disappoint me. The overall performance is very consistent with the positioning of desktop HIFI. At the same time, due to its small size, easy placement, and other characteristics, it is more suitable for audio playback of mobile devices. It has its own USB decoding, and it is not too picky for the sound card of mobile devices. SongEngine A2+style is oriented towards classical voice, suitable for small music, and the positioning of fresh voice, such as Liang Jingru, Xu Song, As well as the song performance of Jay Chou and other singers, it is suitable for pop style, but not suitable for big dynamic symphony. Therefore, those who like fashion and have requirements for the size of the desktop can go to audition to experience it.

In fact, I said at the beginning that I am an audio enthusiast. In fact, compared with the past, there are few audio devices to play. Now, in most cases, I prefer a convenient, pleasant and durable music style. In the past, I used to stick to various earphones and decoders in school. As I grow older, I start to work, and I prefer a relaxed and pleasant way to listen to music, So I chose a speaker. Instead of wearing headphones, I listen to every note carefully. The 2.0 speaker is the best choice for listening to music. Many people like the 2.1 subwoofer. In fact, when you really understand music and like attraction, you will not be confused by the blockbuster bass. The best choice for listening to music is the transparency of medium and high frequencies and the balance of three frequencies, And listening music and fresh voice are the favorite of most fans.

At present, I don't have many audio equipment on hand. The T200C and Sanuo N35G speakers are my own devices. The N35G is mainly used for my own DIY speakers, that is, many people often say that the mill has been replaced. The N35G's ex factory operational amplifier is really poor, and the effect has been greatly improved after replacing the OPA2604 operational amplifier. The T200C is a little bulky. As a desktop multimedia, it is usually responsible for watching movies and listening to music. What always bothers me is that the T200C is too large, which makes the desktop a little too big to fit. In itself, I am looking for the desktop to facilitate listening, while the acoustic engine A2+is relatively small, so I want to locate the desktop HIFI, which is why I particularly want to experience.

Although the three devices differ greatly in price and positioning, this comparison is mainly about price, sound, and different positioning to understand the characteristics of these three speakers. Sound engine A2+mainly locates desktop speakers and mobile HIFI speakers, while Sannuo N35G locates entry-level multimedia speakers, T200C locates high-end multimedia speakers, and bookshelf speakers. The prices of the three speakers are from high to low, which is more than double the price difference T200C>Sound Engine A2+>Sannuo N35G.

How are the three speakers different in sound performance? Compared with the Sannuo N35G, the sound engine A2+has clearer sound, stronger permeability in middle and high frequencies, and stronger hearing tolerance. It is weaker than the Sannuo N35G in the sense of volume in low frequencies. In terms of analysis, instrument separation, instrument positioning, The acoustic engine A2+also has an absolute advantage. Among the detailed sounds, the acoustic engine A2+has more details, and can hear more details than the Sannuo N35G. However, it is inferior to the Sannuo N35G in bass depth and volume sense. After all, the N35G large bass unit is real. The acoustic engine A2+is much stronger than the N35G in medium and high frequency, and is much smaller in size. As a desktop speaker, it has a higher degree of vocal reproduction than the N35G and better overall quality. This is the embodiment of small volume HIFI.

Compared with T200C, the sound engine A2+is really weak. Although its hearing endurance is no worse than that of T200C, after all, the price of T200C is more than twice that of sound engine A2+, and the volume of T200C is several times that of sound engine A2+, which makes it better than sound engine A2+in terms of medium, high frequency and low frequency. In near-field listening, the sound engine A2+human voice has the same feeling of listening very close in front of you, The T200C is a little farther away, and the acoustic engine A2+is relatively more suitable for listening closer.

In pop music, Sound engine A2+is more suitable for classical, vocal, light music and other types of style songs, while Sannuo N35G is suitable for rock songs. In fact, as a multimedia entry speaker, it is more suitable for watching movies and other applications. The T200C, on the other hand, is more inclusive, with three frequencies having characteristics. It is equivalent to A2+in high frequency, better than A2+in medium frequency, and better than N35G in low frequency. However, it is large, as shown in the figure, and the desktop can hardly fit.

With the sound engine A2+, the desktop becomes much more empty immediately, and the small HIFI has an advantage on the desktop.

Compare the volume of T200C with that of It can be seen from the volume of acoustic engine A2+that acoustic engine A2+has considerable advantages in volume, and it is a HIFI speaker that really positions the desktop, while the T200C is more inclined to the bookshelf and needs a bracket to support it.

The simple comparison between Sound Engine A2+and N35G and T200C is mainly to reflect the difference of various positioning speakers. N35G positioning introductory multimedia is suitable for watching movies, playing games and watching videos. It is more omnivorous. The acoustic engine A2+is more suitable for listening to near-field music and HIFI. It has many advantages in vocal reproduction, detail positioning, etc. The T200C is positioned as a medium and high-end multimedia speaker, giving consideration to music and movies, but it is large and expensive. The right way to listen to music is to choose a suitable speaker. After using the acoustic engine A2+, I feel that the small size of the acoustic engine A2+is really convenient. It can be heard on the desktop. It is convenient to disassemble and assemble, and does not occupy any volume.

Speaking of audio experience, I unconsciously said a lot. I like to experience various audio devices and listen to music of different styles. The sound engine A2+itself is a small HIFI speaker, which is compact in size. As a portable HIFI speaker, it can be used for many purposes, such as connecting to tablets, mobile phones, or connecting to audio quality MP3 players and recording pens. Through the playback of sound engine A2+, It is very convenient to listen to high-quality music anytime and anywhere. Compared with ordinary speakers, Sound Engine A2+has obvious advantages in sound quality and can become the first choice for home desktop HIFI speakers.

In the experience of more than a week, I wanted to cook Sound engine A2+ The speaker, but the time is limited, so I believe that the speaker will reach a better state after meeting the service life. In terms of experience, this speaker, as a 2.0 speaker, is more suitable for listening to music, and is suitable for ordinary household desktop speakers, As a desktop HIFI speaker, Sound Engine A2+has no obvious shortcomings. It is a relatively balanced desktop HIFI speaker. However, the voice experience is more subjective. It is suggested that the online friends who are qualified should listen to it on the spot. Ear receiving is the king's way. This has always been my motto for playing audio. The experience of acoustic engine A2+is over here. After the running in period, if there is any new sense of hearing, we will continue to share it with you. thank you.
