Edifier S350DB Speaker Review

EDIFIER released a high-quality 2.1 Bluetooth speaker-S350DB, which continues the retro design. Equipped with a high-quality satellite box and an 8-inch subwoofer, it supports Bluetooth 4.1 aptX and is a versatile product. Whether used to listen to music, as a PC desktop speaker, or a small living room multimedia speaker, it has an excellent audio performance. Suitable for users who have specific requirements for sound quality.

Edifier S350DB

The Edifier S series has a long history and was established in 2001. It is a high-end series used to demonstrate the latest electro-acoustic strength of the Edifier. The speaker system is regarded as a small bookshelf box with extra bass. Therefore, the 2.1 speakers of this generation have carefully designed the crossover according to high-end bookshelf speakers’ standards.

Appearance and Driver

The S350DB satellite box is made of MDF board and decorated with a red maple PVC skin. It is a whole dark red from a distance, and when you look closely, you can see the wood grain. In short, whether you like retro or simple modern home, S350DB can show its unique temperament.
The Edifier S350DB uses a 3/4-inch titanium diaphragm tweeter and a 3.5-inch aluminum diaphragm mid-woofer, carrying 15 watts and 25 watts, respectively. The new speakers will have advantages in terms of resolution and transients.

Another unremarkable but essential change is that the mid-woofer uses a cast aluminum basin stand. The cast aluminum basin rack has much better strength and is not so easy to shake itself. Aluminum is not magnetically conductive, so it will not affect the magnetic circuit. The traditional crossover is no longer needed in the satellite box due to the use of digital crossover technology.

The subwoofer uses an 8-inch woofer with a power of 70 watts. The long-stroke design allows the diaphragm to drive more volume of air to enhance the sense of quantity. This speaker also uses a cast aluminum basin stand. The appearance of the subwoofer is trendy, simple, and elegant. The appearance is close to a cube, but this shape has a negative side for sound quality, and standing waves are easily formed in the box.

Upgrated Chip Adaption

The digital receiving chip uses TI TLV320AIC3254. That is a multi-function chip, including CODEC, ADC signal to noise ratio up to 93dB. It also has a built-in programmable DSP, which can be used for digital frequency division processing, and has a variety of functions.

S350DB uses three Class D digital amplifier chips, among which TAS5707 and TAS5713 are used to drive the high and low sound units of the satellite box, and TAS5754M drives the subwoofer.

The design of the digital crossover plus digital power amplifier makes the crossover more controllable. Edifier adopts this technology, which has been dramatically improved in the mid-frequency part. The application of new technology has also allowed Edifier to use metal diaphragm speakers boldly. According to the official statement, the latest digital technology will enable them to find a way to control the metal diaphragm defects. Compared with some products in the past, the new technology makes the hearing less burr-prone and maintains high transient and high resolution of the metal diaphragm.

Sound Quality

High-frequency Performance

The S350DB uses a 3/4-inch titanium diaphragm tweeter. It does not deliberately display the unique sharp listening sensation of the titanium diaphragm tweeter. On the contrary, it has been restricted to a certain extent to suppress the burr-like feeling that metal tweeters are prone to. Doing this will sacrifice a bit of resolution, but the high-frequency performance is more light and bright.

The dynamic, especially the transient performance, has the style of a typical metal diaphragm. The treble is not dry, expressing the style of stringed instruments, even a little silk diaphragm.

S350DB has a high and low bass gain adjustment. If you want a strong sense of metal, you can moderate the high-frequency gain.

Midrange Performance

The digital crossover allows the speaker to achieve a more controlled frequency transition. Its benefits can be fully reflected in the mid-band. The vocal part of it is more neutral, and the male and female voices have an excellent performance, and they are not deliberately rendered.

What is certain is that it is significantly better than the previous generation S2.1 satellite box. In terms of vocal performance, Edifier S350DB is superior to Edifier’s R series bookshelf speaker.

Bass Performance

The crossover point of the S350DB satellite box and subwoofer is about 120-150Hz. If it is adjusted too low, the low frequency of the satellite box will be affected. The crossover point of this band is not easy to hear the sense of direction of low frequencies.

Because the satellite box provides solid and heavy midrange support, it brings convenience to the subwoofer’s design. The mid-frequency is the base range of many bass instruments. The low frequency below 150Hz is used to complete the frequency band and polish. The S350DB’s low-frequency style is more entertainment-oriented, with a low-frequency sense of volume, flexibility, and a soft but not fatigued, enveloping feel.

S350DB is not so picky about the sound source. Even if you use Bluetooth, high frequencies at low and medium volume will not sound too noisy, and there is no problem as a background music speaker. Of course, we still recommend the use of a better audio source. The S350DB is still worth a good audio source. Listening to a good sound source will be more transparent and broader. It is recommended to use a decoder or high-quality sound card analog output.


The S350DB performs very well in the overall sense of hearing. In a 20 square meter room, no matter what distance you listen to, you can feel the strong surround sound effect. Even with Bluetooth, it will not reduce the distortion rate. But after all, with the support of powerful chips and metal diaphragm technology, S350DB is more worthy of a professional sound source.
