Shengqing is a well-known PC-HiFi manufacturer, with rich experience in the production of professional audio equipment and technical accumulation, has developed and manufactured professional audio equipment and related electronic products for Harman Kardon, Gibson, Apple and other companies, and many of its products have won the authoritative magazine What HI-FI? Five-star recommendation, its household products also enjoy a good reputation in the industry.
 
As a kind of computer peripherals, computer speakers have only been popularized in just a few decades, and there are not many brands specializing in the production of computer speakers, and more products come from the new product lines of traditional HiFi brands. Although Shengqing has not been established for a long time, its reputation in the HiFi field is far less than that of Dynaudio, Tianlang (TANNOY) and other top brands, but these brands have focused on the larger volume of bookshelf speakers and home audio and video fields, there are not many products in computer speakers, separate design for desktop scenes, insufficient adaptation and debugging of computer audio sources, and a greater gap in functionality and ease of use. Therefore, the products of traditional audio brands often appear to be high or low in the field of computer speakers.
 
Shengqing is looking at the gap in the market, relying on the original technical strength in the field of computer speakers quickly made a name, and the ease of use and practicality of its products are the key to success. Most of the studio monitors are active speakers, that is, there are power supply and power amplifier modules in each cabinet, and when used, it is necessary to connect the power supply and signal transmission lines separately for each cabinet, and it is also necessary to distinguish the left and right channels, which is more cumbersome to operate. The sound engine integrates the power supply and power amplifier in the cabinet on the same side, and adds Bluetooth input, optical input and other interfaces for desktop and mobile terminals, bringing high-quality monitors into the field of computer audio.
 
The main feature of the sound engine is that most of its models of speakers are made of wood, with good resonance, and the A/B class amplifier is also selected, with outstanding output efficiency, bidding farewell to the inherent cheapness of digital amplifiers. The appearance is a more traditional wooden box type, the shape is ordinary but the details, workmanship and texture are better, the grain of solid wood, exposed screws, and the black speaker grille, imitating the shape of the old HiFi speaker, which is very classic.
 
In the product line, the initials of the sound engine speaker represent different types, A stands for the mid-range series, B is an integrated speaker, and HD is the HIFI series with high sound quality.
 
Among them, A2 is the most popular and best-known model of Soundengine, and has been selected as one of the "Best Computer Speakers" by The Wirecutter, CNET, PCMag and many other technology evaluation media. Its size is not large, the appearance is simple, the built-in USB decoding function can transmit the original digital signal from the computer, to ensure the audio quality, but also inherit the sound engine has always been warm timbre, the high frequency is delicate and not harsh, the middle frequency is mellow, the low frequency is strong and powerful, not inferior to the subwoofer, and the noise floor is very small, the overall tuning is more modern, more suitable for pop music.
 
The HD3 is the most compact model in the HiFi series, with a volume of only 3 inches, making it the ideal choice for compact computer desktops. HD6 of the same series is not suitable for desktop use due to its large size. In terms of sound quality, HD3 is better than A2, the three frequencies are more balanced, and most pop music has a good sound performance, and it also supports low-frequency adjustment, which is brighter and more prominent when the mid and high frequencies are turned on, and the vocals are prominent, and the desktop resonance is also reduced.
