With the continuous development of the smart home industry, more and more smart audio devices are emerging. However, whether it is smart Bluetooth speakers or smart wifi audio, if you want to pursue good audio quality, you should choose traditional active audio to meet our needs. Today, we bring you a bookcase speaker: Audioengine A5+, which is produced by Audioengine, a medium and high-end audio brand in the United States. It is an upgraded model of A5 launched in 2006. The details of internal acoustic design have been continuously optimized over the years, and it has been very mature and perfect, which has passed the test of time.

appearance:

Sound Engine is a medium and high-end brand from the United States. Before the establishment of the brand, the team mainly produced customized monitoring audio equipment for professional recording studios, and later transformed to produce household indoor audio products. Because it is an American brand, the packaging of Songqing A5+is all in English.

The A5+is packed tightly. There is thick foam at both ends of the box. The speaker is firmly fixed, which can protect it during transportation.

The speaker is placed in two flannelette bags, and the accessories are very rich. It has speaker connection cable, power cable, 3.5mm jack connection cable, RCA connection cable, remote controller and instructions. The instructions are all introduced in English, not in multiple languages. In fact, it can be considered to add instructions in multiple languages.

Sound Engine A5+has three color options: high gloss white, satin black and carbonized solid bamboo. The A5+N version in my hand is a special version of carbonized solid bamboo, which looks more textured and is more suitable for home placement. The caramel color of the box is naturally formed through special baking process rather than dyeing.

The sound engine A5+of the special version of solid bamboo is very meticulous. It is different from the medium density board materials of A5+W and A5+B, and is made by pressing bamboo mixed resin. The unique natural density of bamboo makes it more pleasant than the sound quality of MDF speakers.

The sound engine A5+speakers are composed of a pair of 2.0 speakers with 5-inch woofers. The package weight of the speakers is 14kg. Since all the circuit modules are integrated in the main speakers, the main speakers are heavier than the sub speakers, and the speakers are also relatively large. Therefore, to achieve the desired effect, the two speakers need to be placed at a certain distance.

The bass unit of the speaker is made of Kevlar material. Kevlar is used to make bulletproof clothes. It has high strength and light weight. This feature is very suitable for making speakers. It has a wide frequency response range, low distortion, warm and mellow mid frequency, deep and thick low-frequency, strong and powerful, and can give good consideration to the speed and hearing endurance of mid and low-frequency. Because the outer layer is not designed with a speaker cover, you can see that the diaphragm vibrates with the music rhythm when playing music, especially when playing Hip Hop and other strong rhythm music.

The tweeter unit of the speaker adopts 20mm silk film dome tweeter, which has soft and delicate hearing and good extensibility. However, due to the bare design, it should be carefully protected at ordinary times. The cover of the tweeter is designed with an acoustic guided wave horn, so that the sound waves can be concentrated in the golden area for listening, which can enable users to obtain better junction clarity and sound field width. However, since there is no speaker cover design, it needs to be carefully protected at ordinary times.

There are two circular plastic designs on the lower left corner of the front panel of the A5+main speaker. On the left is the power indicator of the speaker, and on the right is the infrared receiver of the speaker. You can set the volume up and down, mute and sleep modes of the speaker through the remote control.

The volume knob of the sound engine A5+speaker is a stepless digital adjustment, which can be freely rotated from left to right. Different from the design of ordinary potentiometer, it avoids the noise caused by mechanical aging of ordinary volume potentiometer after a long time of use. This volume knob also has the function of automatically memorizing the volume. Press it to switch to the mute mode.

There is a sponge rubber pad at the bottom of the speaker, which is not very thick, and can effectively reduce the resonance effect when the speaker is loud; There is a fixing hole in the middle of the bottom, which can be used with the sound rack.

The port settings of A5+speakers are relatively rich, and they are concentrated on the back of the main speaker, which not only saves the trouble of matching and building a music system, but also makes wiring and connecting other devices simple. Most of the back area of the main speaker is occupied by thick heat sink, which can ensure good heat dissipation effect.

The sound engine A5+speakers adopt the slit phase inversion hole design, which is different from the circular phase inversion hole design of most speakers. The slit phase inversion tube can effectively eliminate the wind noise of air flow, more conducive to the release of low-frequency energy from the speakers, and further improve the sound permeability and purity.

The sound engine A5+speaker has one 3.5mm input interface and one USB interface, but this USB interface does not have the reading function, it is just a power supply interface, which can be used to charge portable players or mobile phones. In addition, there is a set of RCA input and output ports, so that two sound sources can be connected. You can add a subwoofer to the speaker through the RCA output port to get a better music experience. There are two metal cylindrical interfaces below the port, which are connected to the output port of the subwoofer. All the ports are gold-plated to improve the anti-interference and avoid the attenuation and distortion of the audio signal caused by long-term use.

Below the main speaker is the switch key and power socket of the speaker. The red key below the switch key is the voltage switch, which supports 110V and 220V voltage specifications. The Bank of China version has been preset to 220V since it left the factory. Please do not touch it randomly during daily use. Below the voltage switch is the fuse interface of the speaker. When the speaker may be damaged, the fuse will blow itself. At this time, the user can replace one by himself to avoid damage and maintenance of the speaker.

The back design of the A5+subwoofer is very simple. There are only two metal terminals, which can be connected to the main speaker for power supply.

Experience:

The connection of the sound engine A5+speaker is still very simple. Although the A5+can quickly connect with the audio playback device through the 3.5mm input interface, it is recommended to use the RCA input interface if possible to obtain a better music experience. After connecting the power supply and input interface, finally connect the main speakers and the auxiliary speakers through the speaker cable, and we can start our music journey.

The first is the music playing experience after connecting with the mobile phone through the 3.5mm output interface. Although this connection method can not give the best effect to the speaker, it is better than convenience. The test tracks selected here are Kenny G's The Essential Kenny G, Hawks' Hotel California, pure music Butterfly Lovers and Crying Sand, all in lossless format. Of course, since I am not a music enthusiast, I just want to talk about my personal feelings here for reference. Although it is connected through a 3.5mm output port, the sound engine A5+speakers are relatively balanced in terms of tri band performance. At the beginning, the sound of the speakers is generally warm, beautiful and pleasant in treble, clean and mellow in midrange, and not particularly heavy in bass, which is good enough for this price.

The sound engine A5+speaker is relatively large, and it will appear slightly crowded on a smaller computer desk. After connecting the speaker to the computer, try to listen to the above songs again. Because no decoder is used, the effect has not improved significantly. With the increase of the sound, there will be a clear sense of vibration on the table, which will affect the sound quality. It is recommended to equip a speaker rack if conditions permit.

In addition to being used as a computer speaker, the Sound Engine A5+speaker can also be connected to the TV at home. The effect of using it as a TV desktop speaker is also very good. Whether listening to songs or watching movies, it can bring us a more shocking feeling. Especially this bamboo special version is easier to integrate into various home environments.

Conclusion:

As a classic bookcase speaker produced by Sound Engine, Sound Engine A5+speakers give me a very satisfied overall feeling, especially the special version of Sound Engine A5+N solid bamboo in my hands, which is still worth affirming in terms of appearance design and workmanship. The use of special bamboo materials can bring better sound quality than wood and plastic materials. Of course, I am not a professional musician, and there are many subjective factors in judging the sound quality of speakers. However, compared with this price, Sound Engine A5+speakers are really a good choice.
