Short answer: the JBL 4305P if sound quality matters most, the Edifier R2850DB if price matters most. The JBL 4305P ranks #40 of 113 powered bookshelf speakers, rated 4.4/5, at $1,499.99. The Edifier R2850DB ranks #100, rated 3.8/5, at $499.99, $1,000 cheaper.
The JBL 4305P is the better-sounding choice. The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. It keeps a wired aux input, which the Edifier R2850DB lacks. The tradeoff: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.
Why pick the Edifier R2850DB: A large self-powered three-way pair with digital and analog source switching and proper left/right separation. Watch for: The big cabinets need real stand or furniture space, and their bass is slightly boomy.
Buy the JBL 4305P when sound quality outweighs the price for you, and the Edifier R2850DB when the price outweighs sound quality instead.

The Two Speakers In Full
JBL 4305P: $1,499.99 per pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors. Measured bass extension of 45Hz (-3dB).
Cons: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle. Limiting becomes relevant at high output, particularly with bass-heavy music. It suits near- to midfield listening better than the largest high-output systems here. Erin measured about 8dB lost near 50Hz at the highest drive level and reached roughly 93dB unweighted at 2m in-room.

Edifier R2850DB: $499.99 per pair Amazon eBay
Pros: A large self-powered three-way pair with digital and analog source switching and proper left/right separation. Consumer Reports found accurate, detailed sound with strong, deep bass, a broad enough soundfield and enough clean output for a large room. It is a compelling simple system for TV, desktop or living-room music without buying a separate amplifier.
Cons: The big cabinets need real stand or furniture space, and their bass is slightly boomy. Consumer Reports also hears mildly grainy/hazy mids, subdued treble and a two-dimensional image despite the two cabinets. As an integrated system it is less upgradeable than separate passive speakers and an amplifier.
