Edifier R2750DB MKII 2.0 bookshelf speakers walnut with Bluetooth, RCA and optical input

Edifier R2750DB MKII 2.0 bookshelf speakers in walnut finish offer a compact stereo solution with Bluetooth wireless connectivity, as well as wired RCA and optical inputs. Intended for desktop setups and small rooms, this speaker pair aims to reproduce music and multimedia with clear midrange and refined high frequencies while integrating into PC, TV and music player systems via multiple connection options.

Advantages

The speakers combine wireless Bluetooth streaming with physical RCA and optical inputs, allowing flexible connection to modern and legacy devices. The walnut cabinet provides a neutral acoustic enclosure that supports stable sound dispersion, while the 2.0 configuration preserves stereo imaging in limited spaces. Integrated tone balance and crossover tuning deliver consistent mid/high clarity for vocals and instruments.

How to use

Place the left and right speakers on stable surfaces at approximately ear level when seated, keeping a moderate distance between them to maintain stereo imaging. For Bluetooth playback, pair your phone, tablet or computer with the speakers following the standard Bluetooth pairing procedure. For wired sources, connect the source device to the speakers using an RCA cable for analog output or an optical cable for digital output. Adjust the volume and tone controls on the speakers or source device to achieve the desired balance.

Usage recommendations

Position the speakers away from walls where possible to reduce bass coloration and allow clearer imaging. Use the optical input for TV connections to minimise latency and preserve digital signal quality; use RCA when connecting older audio equipment. For best results in small rooms, avoid placing the speakers directly in room corners and perform minor angle adjustments toward the listening position.
