Edifier S355DB: Hi-Res 2.1 Speaker Set with wireless subwoofer released

The S355DB utilizes a structured driver arrangement to ensure sound clarity across the entire frequency spectrum. The two satellite speakers feature 3.5-inch aluminum midrange drivers paired with 1.5-inch titanium dome tweeters for high-frequency detail reproduction. The low frequencies are handled by an 8-inch subwoofer that extends down to 44 Hz. To avoid cable clutter and allow strategic placement in the room, the subwoofer is connected to the main system via a 5.8 GHz wireless link.

The system delivers a total output of 150 W RMS via a tri-amping architecture. By providing dedicated amplification for each driver, the system reduces distortion and stabilizes dynamic reproduction. This is further refined by a 24-bit/96 kHz digital signal processor and an active 3-way crossover that provides smooth transitions between bass, midrange and treble.

Connectivity and wireless standards

To support high-resolution audio over wireless connections, the S355DB features Bluetooth 6.0 and LDAC technology. This combination enables transfer rates of up to 990 kbps, preserving the details of high bit rate audio files. Thanks to multipoint Bluetooth, users can switch between devices such as smartphones and laptops without having to pair them again.

For wired integration, the system features HDMI eARC, allowing it to act as the primary audio output for modern TVs while supporting HDMI-CEC for synchronized on/off and volume control. Other input options include USB-C for digital sources as well as optical, coaxial and analog line-in connections.

User interface and design

The S355DB offers multiple levels of control. The physical controls for volume, bass and treble are located on the side of the active speaker, while a remote control manages the input sources. For more comprehensive customization, the Edifier ConneX app integrates a 9-band equalizer and predefined sound modes to adapt the audio profile to the room acoustics or specific content types.

Visually, the system is available in black or in a wood look. The design features clean lines and professional proportions, while the wireless design of the subwoofer allows users to optimize the acoustic layout of their room without the constraints of cables.
