In the past two years, more and more audio devices have been used, and ears have been raised more and more. A variety of portable Bluetooth speakers at home are small and compact, but there is still a gap between the sound quality and active speakers. Not to mention earplugs, it's okay to go out while you're out and listen to your ears at home. So I started to pay attention to the desktop 2.0 speaker. This kind of speaker doesn't need to occupy too much space while ensuring the sound quality. Before that, we gave you the sound engine B2 Bluetooth speaker related test, but this time we are not introducing the Bluetooth speaker, but another product of the Sound Engine - Audioengine A2+ Advanced Desktop Active Speaker. . Soundengine (Audioengine), a well-known American audio brand, has been established for nearly 10 years. It has a good reputation in Europe and the United States. Its multiple products have received the "What HI-FI" five-star recommendation from the audio-visual authority magazine. After many years of experience in research and development of professional audio equipment and technology accumulation, the home audio equipment also has the quality of professional-grade products, and has made achievements in the field of desktop high-quality speakers. This time the sound engine A2+ combines compactness, lightness and sound quality. It is an upgraded version of the A2 that went on sale in 2007. The details of the internal acoustic design have been optimized over the years. After a test of time, it is already mature and perfect.
The sound engine A2+ package is similar to the sound engine B2. This is also the consistent practice of many brands. It continues the family design and has a better brand visual recognition effect.
To open it, I have to say that this set of speakers is really compact, but its materials are very solid, weight is very heavy, and the weight of the left and right boxes is 1.6 kg and 1.4 kg, respectively. The box is made of hand-polished wood. The advantage of using wood as a box is that the density will be higher and the sound will be thicker than with plastic. The surface of the box adopts a costly matt paint process, the overall uniform color, looks very elegant.
Although small in size, the sound engine A2+ configuration is unambiguous. It uses a 2.75-inch Kevlar fiber woofer and a 20mm silk screen tweeter. However, this time the sound engine does not come with a box mesh cover. If you have children, you need to be careful. If the speaker is used to practice sunflower acupuncture, it is not a joke.
The acoustic engine A2+ adopts a slotted inverted hole on the front of the speaker. This shape of the inverting hole can improve the transparency and purity of the sound more than the circular hole . I used to play several sets of high-end speakers, the inverted hole is straight bar.
Turned to the back of the shocked, so compact body, but there is such a complete interface is rare. The acoustic engine A2+ has RCA and 3.5mm two input ports, but also through the USB interface external digital audio system, it also provides a set of RAC preamp output, can be connected subwoofer or additional speakers. In this way, whether it is a mobile phone, a lossless player or a power amplifier, everything can be connected.
All ports of the acoustic engine A2+ are gold-plated, and the connection between the main and auxiliary cabinets is clip line. Simply insert the speaker cable into the hole and tighten the knob to tighten it. The horn line also distinguishes the color of the knob, so you don't need to worry about connecting the wrong line.
The bundled bundles of wires are all connected like this. The sound engine A2+ has a metal cooling plate on the back of the box, which can provide a better heat dissipation effect to the internal circuit. This is also what many multimedia speakers do not have.
The bottom of the box is a non-slip mat and there is a small hole in the middle. Once you want to hang the speaker, this hole will come in handy.
When we used active speakers to connect to computers to listen to songs, the final sound quality usually depends on the quality of the computer's analog output signal, but the sound engine A2+ can transfer the most original digital signals from the sound source through the USB port, and then internally. Digital signals are converted to analog signals.
The acoustic engine A2+ can achieve this kind of digital-to-analog effect, mainly because it has a built-in USB sound card, which can directly read the original digital signal from the USB interface, and perform signal processing inside the sound box. The pure sound comes from this .
For the audition repertoire, we selected female voice works such as "Cry of Sand", cello "G-string aria", chanting "League-face ambush" and symphony "Hunting polka".
The acoustic engine A2+ is very good in bass, and it can be said to be small and big energy, and that sound can only be described by “澎湃â€. And its IF performance is also more dazzling, the general desktop monitor equipment, in order to restore the timbres to the maximum extent, are to "white boiled water" to adjust the direction, and the acoustic engine A2+ can do to ensure the sound of the true reduction On the basis of this, it is more appropriate to listen to sounds, which is inseparable from the sound of the technology accumulated by many years. At high frequencies, the performance of the Sound Engine A2+ is less dazzling than in the low-mid frequencies. However, it is still relatively bright. Especially when listening to female voice works, there is no such boring feeling of breathlessness.
It has always been thought that large speakers have great energy, but the performance of the acoustic engine A2+ makes me stand up to the small speakers. Even if you have enough space on the table like me, this figure can make such a sound. I think it is worth the money. The acoustic engine A2+ is more suitable for pop music, but if you like to sleep at night, it's good enough for low-frequency performance, it is enough to make you shake your head and shake your head. Although only 2.0 speakers, there is no special subwoofer, but the sound engine A2 in music and even movies, games, can easily navigate.
