Short answer: the Genelec 8351B on measured sound quality, the Edifier R2850DB on price. The Genelec 8351B ranks #4 of 113 powered bookshelf speakers, rated 4.8/5, at $9,900. The Edifier R2850DB ranks #100, rated 3.8/5, at $499.99, $9,400.01 cheaper.
What the Edifier R2850DB does well: 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.
The Genelec 8351B is the better-sounding option. The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. It has an adjustable EQ, which the Edifier R2850DB lacks. Watch for: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material.
Buy the Edifier R2850DB when the price outweighs sound quality for you, and the Genelec 8351B when sound quality outweighs the price instead.

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.

Genelec 8351B: $9,900 per pair B&H Photo Video eBay
Older model: the Genelec 8351A (ranked lower, estimated 4.6/5).
Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8341A (smaller bookshelf, ranked lower, rated 4.8/5), the Genelec 8361A (larger bookshelf, ranked lower, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).
Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.
