Edifier MR4 Studio Monitors — Flat Reference Sound at Near-Field Prices

The Edifier MR4 is a 2-way active near-field monitor pair aimed at home producers and desktop listeners who want honest playback without flagship pricing. Each cabinet pairs a 1-inch silk dome tweeter with a 4-inch MICA-blended woofer, driven by a Class-D amplifier delivering 42 W RMS total. Bedroom studios, podcast rooms, and PC setups benefit from a flat, uncoloured window onto a mix.

What Sets the MR4 Apart in Its Class

Inside the active speaker, a Texas Instruments TAS5713 digital amplifier works together with a precision TI ADC chipset, providing a measured SNR up to 99 dB. The onboard DSP manages an inductive and capacitive second-order frequency divider, giving both the woofer and tweeter a clean signal path. Users cycle between monitor mode (red LED) and music mode (green LED) via a front multi-function knob.

Drivers and Amplification — Honest Numbers, Real Headroom

With a 4-inch woofer made of polypropylene blended with MICA, this model stiffens the diaphragm and extends bass depth.

• Total Output Power (RMS): 42 W (21 W + 21 W) — headroom for moderate near-field monitoring.
• The tweeter features a 1-inch silk dome with special coating, delivering fatigue-free treble over long sessions.
• Woofer — 4-inch MICA-blended PP cone that stiffens the diaphragm and extends bass depth down to 60 Hz.

Frequency Response and Signal Path — Tuned by Ear and by KLIPPEL

Over dozens of test passes with the German KLIPPEL measurement system, the MR4 was tuned to flatten its on-axis response.

• Frequency Response: 60 Hz – 20 kHz — full-range coverage for production and casual listening.
• Signal-to-Noise Ratio: ≥ 85 dB (A) — quiet background between tracks.
• Thanks to the TI precision ADC chipset, SNR reaches up to 99 dB for low-noise conversion.

Inputs, Outputs, and Build — Plug-and-Play for Any Source

On the rear panel you'll find balanced 6.35 mm TRS inputs at +4 dBu for audio interfaces and mixers, as well as unbalanced RCA for computers. The I/O is completed by a 3.5 mm AUX input and a front-panel headphone jack with auto-mute.

• Inputs: TRS balanced, RCA unbalanced, AUX unbalanced — covers pro and consumer sources.
• Private monitoring is possible thanks to a front-panel 3.5 mm headphone output with speaker auto-mute functionality.
• Active Speaker Dimensions: 140 × 228 × 197.5 mm — compact desktop footprint.
• Cabinet Material — MDF wood construction reduces resonance.

Who Should Pick These Monitors

Bedroom producers, podcasters, and home-studio creators who need a flat, honest reference without paying flagship prices will appreciate this pair. PC listeners and keyboard players stepping up from bundled speakers can expect more accurate sound. Casual listeners may switch to music mode for relaxed sessions, while mix work remains anchored in monitor mode.

Edifier — Two Decades of Accessible Audio Engineering

For over 25 years, Edifier has developed speakers and audio electronics to bring measured, lab-grade sound to everyday listeners. The MR4 brings that philosophy to studio monitors, relying on the company's in-house acoustic lab and Germany's KLIPPEL measurement system for a flat response.
