Short answer: the Edifier R2850DB on measured sound quality, the Edifier MR4 on price. The Edifier R2850DB ranks #103 of 119 powered bookshelf speakers, rated 3.8/5, at $499.99. The Edifier MR4 ranks #72, rated 3.5/5, at $169.99, $330 cheaper.
What the Edifier R2850DB does well: A big three way powered pair with deep bass, enough output for a large room, and Bluetooth, optical and RCA inputs. Watch for: The big cabinets need real stand or furniture space, and their bass is slightly boomy.
The case for the Edifier MR4: A budget desktop monitor pair with balanced TRS inputs, tone controls and a front headphone jack. It keeps a wired aux input, which the Edifier R2850DB lacks. It has an adjustable EQ, which the Edifier R2850DB lacks. Watch for: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend.
Buy the Edifier R2850DB when sound quality outweighs the price for you, and the Edifier MR4 when the price outweighs sound quality instead.
