Active Bluetooth Bookshelf Speakers with Room-Filling Hi-Fi Sound

Active Bluetooth bookshelf speakers bring genuine hi-fi performance to desktops, living rooms, and small studios when built around a 100% MDF wooden enclosure with a 10-degree upward baffle tilt. The Edifier R1855DB Black Wood directs sound accurately at the listener while suppressing cabinet resonance. Inside, a bi-amplified architecture delivers 70 watts RMS total output, with dedicated amplification for the mid-bass and tweeter channels.

What Sets This Model Apart in Its Class

Digital Signal Processing (DSP) paired with Dynamic Range Control (DRC) keeps output clean at high volumes, while Nomex-diaphragm mid-bass drivers supply tight, controlled low frequencies. The 19 mm silk-dome tweeters finish the top end with smooth, non-fatiguing highs.

Power and Amplification — Headroom for Any Room

Rather than using a single amplifier, this system adopts a bi-amplified topology to give each driver its own channel for greater control and dynamic range.

• Total Output Power (RMS): 70 W (19 W × 2 tweeters + 16 W × 2 mid-bass) — enough headroom for medium-sized rooms
• With a bi-amplified amplifier topology and integrated DSP/electronic crossovers, every frequency band is handled precisely.
• Signal-to-Noise Ratio: ≥ 85 dB (A) keeps background hiss low during quiet passages

Drivers and Frequency Response — Full-Range Clarity

Each cabinet pairs a dedicated mid-bass unit with a silk-dome tweeter, both engineered for low distortion across the audible band.

• Mid-Bass Driver: 116 mm Nomex diaphragm — controlled, articulate low end
• Tweeter: 19 mm silk dome for smooth treble
• With a frequency response stretching from 60 Hz to 20 kHz, the speakers capture everything from deep bass to shimmering highs.

Connectivity and Controls — Wired and Wireless Flexibility

Combining a stable Bluetooth link with a full set of physical inputs and a subwoofer output, users can tailor their setup for any source or room.

• Bluetooth: Version 5.1 — stable wireless streaming up to roughly 10 m
• Wired Inputs: Optical, Coaxial, Line In 1, Line In 2 (RCA)
• Sub-Out Port: RCA line-level output for 2.1 expansion
• The rear panel offers volume, treble, and bass controls, and a full-function remote makes adjustments easy from anywhere in the room.

Who Should Choose This Active Bookshelf Pair

R1855DB Black Wood is the right choice for listeners who want genuine hi-fi sound without committing to separates, an AV receiver, or a stack of components. Desktop audio enthusiasts benefit from clean, full-range output from a computer, while living-room users can replace a soundbar for a proper stereo image. Vinyl and CD owners benefit from the optical and coaxial digital inputs alongside the analog RCA pair.

Edifier's Approach to Accessible Hi-Fi

Edifier has built its reputation on delivering audiophile-leaning specifications at mainstream price points, and this model reflects that philosophy directly. The combination of a real MDF enclosure, bi-amplified topology, and DSP tuning is unusual at this tier, where most competitors rely on plastic cabinets and single-amp designs. A 10-degree angled baffle echoes classic studio-monitor design cues.
