Short answer: the AsciLab C8C. It ranks #1 of 119 powered bookshelf speakers by sound quality (rated 4.9/5); the Edifier R2850DB ranks #103 (rated 3.8/5).
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. The catch: The big cabinets need real stand or furniture space, and their bass is slightly boomy.
The AsciLab C8C is the better-sounding choice. Excellent large powered monitors, with extremely accurate sound and bass deep enough to skip a subwoofer. The tradeoff: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it.
Buy the AsciLab C8C. It is rated higher for sound quality than the Edifier R2850DB.
