Edifier R2750DB MKII redefines versatility with active three-way design and intelligent cost savings

Edifier’s R2750DB MKII combines advanced multi-source connectivity, active three-way drivers, and cost-efficient design, offering a flexible stereo system suited for TV, PC, and music playback, though its size and bass response mark its limits.

Edifier’s R2750DB MKII is a reminder that “bookshelf” can be a generous term. Each cabinet is about 223 x 395 x 280 mm, and the pair weighs 16.57 kg, so this is a sizeable active stereo system rather than a compact desktop speaker set. The design combines a 7-inch woofer, a 4.5-inch mid-range driver and a 1-inch silk-dome tweeter in a three-way layout, with a claimed 144W RMS output and support for HDMI eARC, optical, coaxial, line-in and Bluetooth 6.0. Edifier also lists Hi-Res Audio and Hi-Res Audio Wireless certification, plus multipoint Bluetooth and a SUB OUT for expansion.

In practice, the appeal is not just the specification sheet but the breadth of use cases. According to Edifier’s product information and independent reviews, the MKII is intended to serve as a TV speaker, PC speaker and conventional stereo system at the same time. HDMI eARC adds the convenience of television volume control and automatic power behaviour on compatible sets, while Bluetooth makes the system easier to use with phones and tablets. The review material also notes support for SBC and LDAC, which matters more in real-world listening than the marketing label of Bluetooth 6.0 alone.

The hardware architecture is more interesting than the price would suggest. The system uses separate amplification for each of the three drivers, and the test teardown described a fully active arrangement in which the passive cabinet does not contain a conventional three-way crossover. That means the linking cable between the two speakers is part of the electronics design, not a simple substitute-wire scenario. The review also found that the bass section uses a PBTL arrangement in the amplifier stage, while the higher-frequency paths are handled separately, which helps explain the model’s controlled presentation and its relatively efficient use of modest internal power hardware.

The same teardown suggests Edifier has saved money in careful places rather than obvious ones. The review found a 24V, 90W power supply and no large traditional heat sink, with thermal management instead handled through board copper, through-hole design and the rear panel assembly. It also found a separate HDMI/eARC daughterboard and a JieLi wireless module, but no clearly distinct stand-alone audio DSP board. That points to a fairly integrated signal path, with much of the processing embedded in the amplifier and interface stages rather than spread across more expensive specialist components.

That approach seems to have been chosen to balance versatility and cost, and the result is a speaker that is easier to place in a living room than a soundbar in some respects, but less forgiving in others. The cabinets are large, the box-to-box link is proprietary, and the subwoofer output is meant as an add-on rather than a fully featured bass-management system. Still, the combination of active three-way separation, HDMI eARC, analogue inputs and Bluetooth multipoint gives the R2750DB MKII a rare level of flexibility in this class.

On sound, the overall picture is of a speaker that aims for control rather than drama. The separate mid-range driver should help with voice clarity and instrument placement, while the woofer section provides useful weight without pretending to reach into true sub-bass territory. That makes the MKII a plausible choice for mixed listening: television, speech, jazz, rock and everyday streaming, with a subwoofer recommended if deep film effects or electronic bass are a priority. In short, Edifier has built a technically tidy system that avoids obvious compromise, even if its size and bass limits mean it is not the universal solution its feature list might suggest.
