Design and Build
The Edifier MR4.5 sports a professional, understated black finish suitable for both studio and home environments. Its compact bookshelf form factor, with each speaker measuring 8.19 inches deep by 5.51 inches wide by 9.61 inches high, is engineered for nearfield placement on desktops, speaker stands, or shelves. The build quality, as noted in owner feedback, is described as superb, with thorough attention to detail in construction and finish. The main speaker unit houses all controls, inputs, and the amplification circuitry, while the secondary speaker is passive, connected via the included speaker cable. A notable design element mentioned in the specifications is the dimpled tweeter waveguide, which is intended to deliver a wide and consistent sound dispersion pattern, crucial for maintaining audio accuracy across a listening position.
Performance and Features
Studio-Grade Sound Accuracy
The core performance of the MR4.5 is built around its bi-amped design, which dedicates separate amplifiers to the 4.5-inch mid-bass driver and the 1-inch silk dome tweeter in each speaker, totaling 80W RMS. This design aims for greater control and clarity. The stated flat frequency response of 50Hz to 40kHz is geared towards capturing audio detail without coloration, a key requirement for mixing and mastering. Hi-Res Audio and Hi-Res Audio Wireless certifications indicate the system is capable of reproducing high-resolution audio files, both wired and wirelessly. Owner reviews frequently highlight the surprising depth and control of the bass for the speaker’s size, as well as the overall excellent and accurate sound quality.
Connectivity and Inputs
Connectivity is a major strength of the Edifier MR4.5. It offers a comprehensive selection of inputs to accommodate both professional and consumer gear. On the rear, users will find balanced XLR and TRS inputs for connecting professional audio interfaces, alongside unbalanced RCA and AUX inputs. The front panel provides a 3.5mm AUX input and a headphone output for convenience. Wireless connectivity is handled by Bluetooth 6.0 with support for the high-quality LDAC codec, enabling high-resolution streaming from compatible devices, and it features multi-point pairing. A point noted by an owner is that all inputs remain active simultaneously, which means the unit automatically switches to an active signal without a manual selector.
Precision Tuning and Room Calibration
Beyond basic volume, the MR4.5 provides significant control over its sound signature to compensate for room acoustics. Physical controls on the rear include independent High (±6dB above 10kHz) and Low (±6dB below 125Hz) knobs. For deeper calibration, the Edifier ConneX app unlocks a 9-band EQ, two preset sound effects, and professional adjustments like a low-frequency cutoff filter (20–100Hz with selectable slopes) and an acoustic space control (0dB to -4dB) to reduce bass boost from wall or corner placement. An end-to-end DSP with 24-bit/96kHz processing, a bi-amped active crossover, and dynamic range control works behind the scenes to ensure accurate and transparent sound output.
Setup, Support and Ownership
Setup is reported by owners as straightforward, involving connecting the passive speaker to the main unit, running audio cables from a source, and connecting power. The inclusion of multiple cable types facilitates quick integration with various devices. For optimal performance, utilizing the room calibration features via the rear knobs or the Edifier ConneX app is recommended, though this involves a learning curve for new users. The manufacturer provides a 2-year warranty. It is important to note that accessing the full suite of EQ and calibration features requires downloading the separate Edifier ConneX app, which, according to an owner’s note, is one of two Edifier apps available and should be identified correctly.
What Owners Say
Owner feedback for the Edifier MR4.5 is exceptionally positive, reflected in its perfect rating distribution. Reviews consistently praise the outstanding sound quality, with specific mentions of deep, controlled, and rich bass performance that exceeds expectations for bookshelf speakers. The build quality and cosmetic appearance are frequently highlighted as excellent and professional. Users appreciate the abundance of controls and adjustment options, both on the hardware and through the app, allowing for fine-tuning to personal preference or room needs. The multiple input options, including Bluetooth LDAC, are seen as a major convenience. A minor critique mentioned is the desire for a protective grill cover, and some note the documentation is extensive but presented on a large sheet rather than a convenient booklet. The speakers are commonly used successfully in Digital Audio Workstation (DAW) setups for music production.

FAQs
Can the Edifier MR4.5 be used for casual music and movie listening?
Absolutely. While engineered for studio accuracy, the MR4.5 excels as high-fidelity speakers for all audio content. The available tone controls and app-based EQ presets allow users to adjust the sound to their preference for music, movies, or gaming, providing a detailed and engaging listening experience beyond pure monitoring tasks.
What is the advantage of having balanced XLR and TRS inputs?
Balanced connections (XLR and TRS) are standard in professional audio equipment because they reduce noise and interference over long cable runs. If you are connecting the speakers to an audio interface, mixer, or other pro gear that has balanced outputs, using these inputs will provide the cleanest possible signal transfer, which is critical for accurate monitoring during recording and mixing.
How does the room calibration feature work?
The room calibration is managed through controls on the back of the main speaker and the Edifier ConneX app. Features include adjustable low-cut filters to remove unwanted rumble, an acoustic space control to reduce bass buildup from nearby walls or corners, and a desktop control mode. These tools help compensate for the acoustic imperfections of your specific room or placement, leading to more accurate and flatter sound reproduction at your listening position.
Is a subwoofer necessary with the Edifier MR4.5?
Not necessarily. The MR4.5 is designed with a stated frequency response down to 50Hz, and owner reviews note surprisingly deep and controlled bass for its size. For most music production, video editing, and general listening, the built-in bass may be sufficient. However, for genres or applications requiring very deep sub-bass (below 50Hz), or for a more cinematic home theater experience, adding a dedicated subwoofer via the RCA outputs (if available on a connected source) can extend the system’s low-end response.
