Product information

Description

The Edifier MR4-WHITE 21 W studio loudspeaker is a wired, two-way monitor designed for accurate sound reproduction in small production setups and desktop listening. It combines a 4-inch woofer and a 1-inch silk-dome tweeter driven by a Class-D amplifier and digital signal processing to deliver a frequency response down to 60 Hz and clear high frequencies up to 20 kHz. The speaker features balanced 6.35 mm TRS inputs plus unbalanced RCA/AUX inputs and a front headphone output, and is finished in white with a medium-density fibreboard (MDF) cabinet to reduce resonance.

Advantages

The MR4 is tuned using the Klippel measurement system and professional acoustic lab adjustments for a flatter response suitable for monitoring. A Class-D amplifier with TI ADC and TAS5713 DSP provides a high signal-to-noise ratio and precise digital sound control. The 4" woofer with MICA-enhanced PP cone improves low-frequency extension and detail while the coated 1" silk diaphragm produces smooth treble. The MDF enclosure reduces coloration and a second-order inductive/capacitive crossover ensures cleaner signal delivery to both drivers. Dual sound modes let you switch between monitor and music playback.

Suitable for

  • Home and small studio music production and mixing
  • Desktop monitoring for content creators and podcasters
  • Nearfield listening and casual music playback in a workspace

How to use

Connect the MR4 to your audio source using a balanced 6.35 mm TRS cable for professional gear or RCA/AUX cables for unbalanced sources. Place the speakers as nearfield monitors, forming an equilateral triangle with the listening position and with tweeters roughly at ear level. Rotate the front multifunction knob to set volume; long-press to power on/off and double-click the knob to toggle between monitor and music modes. Use the front headphone output for private monitoring when needed.

Usage recommendations

For accurate monitoring, allow the speakers to warm up for several minutes and use the balanced TRS connection and monitor mode when mixing. Position the speakers on stable stands or isolation pads and keep them at ear height and clear of reflective surfaces for best low-frequency performance.

Amplifier

Signal-to-Noise Ratio (SNR): This is the ratio of signal intensity to noise intensity.
85 dB
Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.

Amplifier class: An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. Power amplifier circuits (output stages) are classified as A, B, A/B and C for analog designs, and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device is passing current.
