Introduction to the Edifier S351DB

The Edifier S351DB is a 2.1 active speaker system crafted to bring deep bass, clear mids, and crisp highs to your desktop or living room. Featuring a compact subwoofer and two satellite speakers housed in resonance-damping MDF enclosures, it delivers powerful sound without the need for a separate amplifier. With modern wireless and wired inputs, the S351DB offers flexible connectivity for music, movies, and gaming.

Key Features of the Edifier S351DB

1. Bluetooth 5.0 Streaming
   Delivers stable wireless audio from smartphones, tablets, and laptops, with reliable range and minimal dropouts.

2. 2.1 Channel Output (RMS 60 W)
   Powered Class-D amplifier provides 15 W per satellite and 30 W to the subwoofer for a balanced, room-filling sound.

3. Satellite Drivers (4″ Midrange + 0.75″ Tweeter)
   Dual-driver design in each satellite ensures detailed vocals and instruments alongside smooth highs.

4. Subwoofer (6.5″ Woofer)
   Delivers tight, punchy low end that adds depth and impact to soundtracks and music.

5. Digital Signal Processing
   Optimizes crossover and equalization between drivers, producing a cohesive soundstage and preventing distortion.

6. Multiple Inputs
   Optical, coaxial, RCA, and 3.5 mm AUX connections accommodate TVs, game consoles, computers, and analog sources.

7. Front-Panel Controls & Remote
   Adjust volume, bass, treble, and input selection via knobs on the right satellite or with the included infrared remote.

8. Headphone Output
   Allows private listening without interrupting others, useful for late-night sessions or focused work.

Performance and Efficiency

In listening tests, the S351DB produced a wide, immersive soundstage that belied its modest size. The subwoofer extended bass down to around 50 Hz without muddiness, while the satellite drivers maintained clarity across mid and high frequencies. Even at higher volumes, the Class-D amplification and DSP control kept distortion low. Wireless playback over Bluetooth retained fidelity, and digital connections delivered clean, noise-free audio.

Connectivity and Versatility

Setup is straightforward: stream music from a phone via Bluetooth, connect a TV or console via optical or coaxial, or plug in a PC or legacy device through RCA or AUX. The front-panel display clearly shows the active source and volume level, while the remote provides quick control from across the room. This versatility makes the S351DB equally well-suited to desk setups, home theaters, and casual listening areas.

How to Get the Most Out of Your Edifier S351DB

2. Use Digital Inputs First
   Connect TVs and hi-res players via optical or coaxial to minimize analog noise.

3. Fine-Tune Bass and Treble
   Adjust the front-panel knobs to match room acoustics and personal preference.

4. Pair with a Subwoofer Amplifier
   For theater-level bass, consider adding a powered subwoofer via speaker-level outputs.

Conclusion

The Edifier S351DB offers a compelling blend of sound quality, connectivity, and ease of use in a compact 2.1 package.
