In recent years, Huiwei has been constantly innovating its audio and video products. While vigorously developing cutting-edge technologies such as multimedia and wireless audio and video, it has also considered the process technology and tuning ideas previously put into high-end models, trying to put them into entry-level and advanced models. In this way, we can not only create new works that are far more cost-effective than competing products at the same price, but also capture more video players, so that everyone can enjoy audio products with excellent audio quality.

D300 This is just one example. From the perspective of product positioning, it may just be an advanced product with a slightly larger size suitable for living room cinema; However, in fact, it is equipped with a magnetic belt tweeter such as Huiwei Baby, and it is still sold in high-end floor mounted loudspeaker box Acoustic panel technology. Under the light of the high-end model, if the D300 can achieve the leap in sound quality as expected, let's see.

Decentralize mature acoustic technology

Generally, video players think that the sound quality of a speaker depends on what unit it uses; But in fact, from the box to the environmental acoustics, these external factors are affecting the actual sound effect of the speaker. Both speaker units and finished audio products have Huiwei Audio. While continuously optimizing speaker unit technology, the speaker unit sound generation and space reflection of the box are also taken into consideration. Just go to the official website of Huiwei to learn about the flagship floor mounted speaker M808. From the front panel of the box to the composition of the unit structure, it highlights the acoustic technology that Huiwei has accumulated for many years.

Time has changed, and now Huiwei Audio focuses part of its research and development on the field of multimedia active audio, and the consumer group of the whole market is becoming younger, so "the first XX for young people" gets its name. For young people who have not yet come into contact with audiophiles, it is not too much to say that creating entry-level and advanced active speakers with sound quality and technical content is the burden of Huiwei Audio.

Having said so much, the main reason is that the protagonist D300 Bluetooth wireless active speaker uses many elements of Huiwei's high-end products. Just like its box surface, the black matte decorative panel is the same type of M808; And the side of the box is also an irregular surface design determined after rigorous calculation and measurement. The purpose of this is to reduce the impact of edge diffraction on sound when sound waves are reflected from the wall to the box, rather than simply paying homage to high-end products.

Learned loudspeaker unit

In addition to the front panel, the constant magnetic field belt tweeter selected by the D300 is also very knowledgeable. This kind of unit has the advantages of higher frequency response and extensibility than the traditional silk film dome, which can show bright and transparent treble, so it has become a lot of high-end Hi -End is the preferred speaker unit of the flagship product. In China, Huiwei Audio is one of the few manufacturers that master the core technology of the unit. In the past, because of the difficulty in processing, it was usually put into high-end products. On the one hand, it overcame the problem of mass production technology. On the other hand, designers also hope to use this product to break the monopoly of speakers of other overseas brands and provide more options for video players.

Although the D300 mid bass unit does not shine with high-end halo, it is a metal unit made of aluminum magnesium alloy. This unit has higher rigidity and reaction speed than the polyethylene, synthetic plastic and paper pots used in ordinary speakers. It can restore music details clearly and accurately; When playing some high-quality recordings, video players can appreciate what the so-called true restoration is.

How should speakers be placed? For video players who are a little familiar with audio and video, it is generally recommended to mount the tripod, which can effectively solve the problem of vibration and bass reflection; But what about the living room theater scene where the space is slightly narrow and only the TV cabinet is empty? Rest assured, Huiwei has thought of this for a long time and has prepared a tripod/desktop mode for the D300. The data of the two modes are stored in the DSP circuit by the designer after actual audition and comparative measurement. When the video player places the D300 on the tripod or desktop, the speaker will automatically start the data of the corresponding mode, and the sound performance will change accordingly to maintain a smooth and natural listening experience.

Considering that video players using D300 will connect to different devices except TV, Huiwei provides speakers with rich physical interfaces, such as RCA, XLR, coaxial and optical fiber. At the same time, the D300 is also equipped with a Bluetooth 5.0 chip solution, which supports protocol technologies such as aptX, realizing stable, high-speed, low loss wireless transmission, and solving the input device problems faced by video players in one step.

Glossy and beautiful sound

The sound performance of overseas audio products with belt tweeter is a kind of shiny and beautiful sound, and so is the D300 with magnetic belt tweeter developed by Huiwei. Play the second fugue in Aaron Lausanne's Unaccompanied Violin Suite, and the endless and skillful violin playing will come to your face. In the face of fast and violent piano sound, D300 will show loose, bright and clear lines. The rich performance details are restored under the strong analysis of D300, which makes people listen to it thoroughly.

The D300 not only has such amazing treble and analytical power, but also is suitable for listening to some dynamic music works thanks to its 6.5 inch metal bass and excellent acoustic structure. Listening to China's first Spring River Moonlight, the D300 shows a fast dive and crisp bass drum, which is exactly the sound that the real drum should make. This shows the strength of the D300's quality. As for the sound field, although the D300 is a bookshelf type speaker, and the sound field is more or less excellent than the floor type speaker, when it is placed on the tripod and the corresponding mode is opened, the overall breadth and depth are also particularly obvious. It is also very suitable for daily listening to classical works such as concertos and chamber music.

With the help of high-end acoustic technology, the D300 combines high-quality units, wireless solutions, DSP and other details to improve the sound performance of this bookcase speaker in terms of sound field, high frequency and comfort. For lazy players, choosing D300 allows you to easily enjoy good audio quality at a more affordable price. For audiovisual players with enthusiasm, the potential of D300 is worth exploring in daily use to create more possibilities.
