Diffusore Edifier MR4 21 W

The Edifier MR4 21 W compact loudspeaker delivers professional, balanced sound in a small footprint. It combines a 1-inch silk dome tweeter and a 4-inch MICA woofer housed in a durable MDF cabinet to provide accurate high frequencies, deeper bass and a near-flat response suited for monitoring and general listening. The speaker offers multiple wired inputs and a headphone output, and its 21 W RMS power and 60–20000 Hz frequency range make it suitable for studio and desktop setups.

Advantages

Designed for clarity and accuracy, the MR4 uses a silk dome tweeter with a special coating for smooth, refined treble and a MICA-reinforced woofer for stronger, more accurate low frequencies. The MDF wooden enclosure reduces unwanted resonance to maintain tonal integrity. Multiple connection options, a headphone output and an adjustable multifunction knob (volume, power and sound mode) provide flexible control and compatibility with audio interfaces, mixers, computers and mobile devices.

• Home studio monitoring and music production

How to use

Use the headphones output for private monitoring. Rotate the front knob to adjust volume, long-press to power the unit on or off and short-press to cycle through available sound effect modes.

Recommendations

For accurate monitoring, position the speakers at ear height and form an equilateral triangle with the listening position. Allow a short warm-up time after powering on and avoid placing speakers directly against reflective surfaces to minimize coloration. Use the balanced TRS input when connecting professional audio equipment for the best signal integrity.
