Short answer: the PreSonus Eris Studio 8. It ranks #99 of 119 powered bookshelf speakers by sound quality, rated 3.9/5, at $419.98; the Edifier R2850DB ranks #103, rated 3.8/5, and costs $499.99, which makes this an easy call rather than a real tradeoff.
The case for the Edifier R2850DB: 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 PreSonus Eris Studio 8: A budget 8 inch studio monitor with XLR, TRS and RCA inputs and room adjustment controls for a conventional studio desk. It has an adjustable EQ, which the Edifier R2850DB lacks. The tradeoff: The large cabinet requires substantial desk or stand space.
Buy the PreSonus Eris Studio 8. It is rated higher for sound quality than the Edifier R2850DB and costs less, so only choose the other one for a particular feature it does better.
