With the continuous development of the smart home industry, more and more smart audio devices are emerging, but whether it is smart Bluetooth speakers or smart wifi audio, if you want to pursue good sound quality, then you still have to choose the traditional Active sound can meet our needs. What is brought to us today is a bookshelf speaker produced by American high-end audio brand Audioengine: Audioengine A5+, which is an upgraded model of the A5 released in 2006. The details of the internal acoustic design have been for many years. To continue to optimize, has been very mature and perfect, after the test of time.
Sound Engine is a mid-to-high-end brand from the United States. Before the brand was established, the team mainly produced professional monitor studio custom monitor audio equipment, which was later transformed into production of home-use indoor audio products. Because it is a U.S. brand, the sound engine A5+ package is entirely in English.
The packaging of A5+ is still very strict. There are thick foam on the upper and lower ends of the box, and the speaker is fixed very firmly, which can play a good role in protection during transportation.
Speakers are placed in two velvet bags, accessories are still very rich, with speaker cable, power cord, 3.5mm jack connector, RCA cable, remote control and instructions, the instructions are all introduced in English, and there is no Mixed use of multiple languages, this can actually consider the introduction of multilingual instructions.
The acoustic engine A5+ has high light white, satin black, and carbonized solid bamboo. The A5+N version is a special version of the carbonized solid bamboo. It looks more textured and more suitable for home placement. Caramel-colored cabinets are not colored by color but are naturally formed by a special baking process.
The solid bamboo special edition sound engine A5+ workmanship is still very meticulous, it is different from A5+W, A5+B MDF material, is compressed by bamboo mixed resin, bamboo's natural density unique to it than MDF material's Speaker sound more pleasant.
The acoustic engine A5+ speaker consists of a pair of 5-inch woofer 2.0 speakers, the package contains a package weight of 14kg, because all the circuit modules are all integrated in the main speaker, so the main speaker is heavier than the secondary speaker, the speaker's head is also considered Larger, so you want to achieve the desired effect, when the two speakers are placed still need to pull a certain distance.
The woofer of the speaker is selected from Kevlar material. Kevlar is used to make the body armor material. The strength is very high and the weight is very light. This feature is very suitable for the manufacture of speakers, with a large frequency response range and low distortion. Listening to a warm and mellow midrange frequency, deep and deep low frequency, strong and powerful, can well take into account the sense of speed and hearing in the low-frequency. Because the outermost layer is not designed with a speaker enclosure, it can be seen that the diaphragm vibrates with the rhythm of the music when playing music, especially when playing strong rhythm style music such as Hip-Hop.
The tweeter of the speaker uses a 20mm silk dome tweeter, which is soft and delicate, and has good extensibility. However, due to the bare design, care must be taken to protect it. The tweeter's enclosure has an acoustic guide horn design that allows the sound waves to focus on the listening golden area, allowing the user to achieve better knot definition and sound field openness. However, because there is no speaker enclosure design, it usually needs careful protection.
There are two round plastic designs in the lower left corner of the A5+ main speaker's front panel. The left is the speaker's power indicator. The right is the speaker's infrared receiver. You can use the remote control to perform volume addition and subtraction, mute, and sleep modes on the speakers. Settings.
Sound volume engine A5 + speaker volume knob is infinite digital adjustment, can be arbitrary rotation, unlike ordinary potentiometer design, to avoid the general volume potentiometer after a long time use mechanical aging noise. And this volume knob also has an automatic memory volume function, press to switch to silent mode.
The bottom of the speaker has a layer of sponge pad, which is not very thick, which can effectively reduce the resonance effect when the large speaker is at a loud volume; there is a fixing hole at the bottom middle position that can be used with the audio frame.
A5+ speaker port settings are relatively rich, have been placed on the back of the main speakers, not only eliminating the trouble with the formation of music systems, but also make wiring and connecting other equipment becomes simple. Most of the back area of ​​the main speaker is occupied by thick heat sinks, which ensures good heat dissipation.
The acoustic engine A5+ speaker adopts slotted inverted hole design, which is different from the circular inverter hole design of most loudspeakers. Slot-type inverter tube can effectively eliminate airflow noise, and it also helps the speaker release mid-low frequency. Energy further enhances the transparency and purity of the sound.
The acoustic engine A5+ speaker has a 3.5mm input interface, a USB interface, but this USB port does not have a read function, just a power supply interface, can be a portable player or to charge the phone. There is also a set of RCA input and output ports so that you can connect to two audio sources. You can use the RCA output port to add subwoofers to your speakers for a better music experience. Below the port there are two metal cylindrical connectors. This is the connection to the sub speaker output port, and all the ports are gold-plated, which improves the anti-interference and avoids the attenuation and distortion of the audio signal for a long time.
The bottom of the main speaker is the speaker's key and power socket. The red key below the key is the voltage switch. It supports 110V and 220V voltage specifications. The BNM version has been preset to 220V before use. Do not toggle. Below the voltage switch is the speaker's fuse interface. When the speaker is likely to be damaged, the fuse will blow off. At this time, the user can replace one of them, to avoid damage and maintenance of the speaker.
The back of the A5+ subwoofer is very simple in design, with only two metal posts that can be powered by connecting to the main speakers.
The sound engine A5+ speaker connection is still very simple, although the A5+ can be directly connected to the audio playback device directly through the 3.5mm input interface, but for a better music experience, it is recommended to use the RCA input port to perform conditions. connection. After connecting the power supply and the input interface, finally connecting the main and sub speakers through the speaker cable can start our music tour.
The first is through the 3.5mm output interface and mobile phone to connect after the music playback experience, although this connection can not make the speaker to play the best results, but wins in convenience. The test tracks selected here are Kenny G's “The Essential Kenny Gâ€, “The California Inn†by the Eagles, the pure music “Butterfly Lovers†and “Crying the Sandsâ€. All of them are in lossless format. Of course, because I’m not What are the music fanatics, so here is just to talk about personal feelings, for reference only. Although through the 3.5mm output port connection, but the sound engine A5 + speaker in the tri-band performance is still relatively balanced, just beginning the sound of the speaker is generally warm, beautiful sound high-pitched, Alto clean alcohol, bass is not particularly heavy, enough Degree, relative to this price, is still very good.
The sound engine A5+ speakers are quite large, and they are slightly crowded on a smaller computer table. After connecting the speakers and the computer, listen to the above songs, because the decoder is not used, so the effect is not significantly improved. As the sound increases, there will be a significant sense of vibration on the table. For the effect of sound quality, it is recommended to use the speaker frame or conditional.
In addition to being used as a computer speaker, the acoustic engine A5+ speaker connects it to a TV in the home. The effect of using it as a TV desktop speaker is also very good. Whether it is listening to music or watching movies, it can bring us The more shocking feeling, especially the bamboo special edition, is easier to integrate into different home environments.
The acoustic engine A5+ speaker is a classic bookshelf speaker produced by the American sound engine. It gives me an overall feeling of satisfaction, especially the sound engine A5+N solid bamboo special edition in my hands, in terms of design and workmanship. Still worthy of recognition, using a special bamboo material can bring better sound quality than wood and plastic materials. Of course, because I am not a professional musician, and there are many subjective factors for the sound quality evaluation of speakers, but relative to this price, acoustic engine A5+ speakers is indeed a very good choice.
