Siblings in Edifier's MR series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Edifier MR5 digs deeper - 46Hz against 60Hz. |
| Built-in power | A | Edifier MR5 has the bigger amplifier (110W vs 42W RMS). |
| Connections | A | Edifier MR5 adds Bluetooth. |
| Size | depends | Edifier MR4 is easier to place; Edifier MR5 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | Edifier MR4 is cheaper - $170 against $350, about 51% less; arguably a different class. |
A Edifier MR5 B Edifier MR4
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Edifier MR5 measures better, Edifier MR4 costs about about 106% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, which makes the cheaper Edifier MR4 much easier to justify. In a large or open-plan room, Edifier MR5 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Edifier MR4 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
