Edifier S351DB - 2.1 System with Wooden Cabinets and 150 Watts

Three types of driver, each with its own amplifier, and 19 kilograms of construction in total. S351DB doesn't rely on compromises: the bass comes from a genuine 8-inch driver in its own cabinet, the midrange from aluminium diaphragms on cast frames, and the treble from titanium tweeters. Every cabinet is wood, because plastic sings along with the drivers.

Key Highlights

• Bass down to 40Hz from an 8-inch driver with cast aluminium frame
• 150 watts split across three independent paths
• All-wooden cabinets for satellites and subwoofer
• Bluetooth with aptX, optical and coaxial inputs

Technology & Benefits

Bass You Can Feel

The 8-inch driver is designed with long stroke and sits on a cast aluminium frame. Metal doesn't flex under load the way plastic frames do - the motor assembly holds its precise geometry even when the diaphragm travels to its extremes. The flared reflex port is calibrated for this particular cabinet, while a 70-watt amplifier drives it all down to 40Hz.

Satellites with No Compromise in Materials

In a 2.1 system the satellites are relieved of reproducing bass - which is why 3.5 inches suffice. The diaphragm is aluminium alloy on a cast aluminium frame, giving a rich, full-bodied midrange. The tweeters are ¾ inch with titanium diaphragms, finely tuned for precise reproduction of the upper register.

Three Paths, Three Amplifiers

The DSP chipset divides the signal into highs, mids and lows before it reaches the amplifier. Each of the three paths gets its own amplification - 15, 25 and 70 watts - and feeds only its respective driver. No driver ever receives frequencies it can't handle well.

Why Wood

Cabinet walls vibrate along with the drivers. With thin plastic those vibrations are strong enough to hear - usually as smeared bass and blurred detail. Wood is heavier and more inert, so resonance stays under control. The system's 19-kilogram weight is a direct consequence of that choice.

Inputs for Everything

Optical and coaxial inputs take a digital signal at 44.1 or 48kHz - enough for a TV, CD player or console. Two line inputs remain for a computer or turntable with preamp, while Bluetooth with the aptX codec carries audio from your phone at above-standard quality.

Control at the Side and from a Distance

Side-panel knobs cover volume, bass, treble and input selection - settings made once at installation. The remote handles the same functions from wherever you listen.

Who Is It For?

S351DB is for people who'd like large speakers but have nowhere to put them. The satellites occupy the footprint of a book, while the subwoofer carries the full weight of the low end from a position you choose freely. It suits a living room, bedroom, study, or duty as a TV system.

Expert Tip from vsystem.bg

Take time over the subwoofer's position - with bass reaching 40Hz, the difference between a good and a bad spot is substantial. Place it temporarily where you normally sit, play music and walk around the room: wherever the bass sounds best is where it belongs. Position the satellites so the tweeters aim at your ears. When connecting a TV, use the optical input and set PCM output in its menu.

FAQ

What's the difference from the S350DB?
The two models are very close - S351DB reaches one hertz lower, the satellites are slightly more compact, and the whole system is noticeably heavier. The rest of the specification matches.

Do I need an amplifier?
No. The amplifiers are built into the system, with the source connecting directly.

Why are the satellites so small?
Because they don't have to reproduce bass - that's the subwoofer's job. It lets them stay compact without compromising the sound.

Can I connect a turntable?
Yes, provided the turntable has a built-in phono preamp or you use an external one. The connection goes through either line input.

Does it have an HDMI input?
No - optical and coaxial inputs are provided for a TV. For HDMI eARC, consider the S355DB.
