Short answer: the Adam Audio S2V for measured refinement, the Edifier R2850DB only as the large budget three-way. The S2V’s spinorama shows excellent driver blending through an imperceptible crossover between the 7-inch woofer and AMT tweeter, with distortion measured 70dB down at 1kHz, though an intentional shelving curve dips the low bass roughly 200-500Hz. The R2850DB is a three-way speaker, but it is quite large and heavy.
Buy the Edifier R2850DB when the price outweighs sound quality for you, and the Adam Audio S2V when sound quality outweighs the price instead.

The Two Speakers In Full
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.

Adam Audio S2V: $3,399.98 per pair Amazon eBay
Pros: A 7.98 ideal-subwoofer score and relatively even listening-window response support a strong role as a subwoofer-assisted studio monitor. The review’s low-distortion findings add useful evidence beyond amplifier ratings, and onboard DSP permits tailored adjustment. The review measured distortion about 70dB below the signal at 1kHz. Measured bass extension of 52.7Hz (-3dB).
Cons: Measured -3dB extension is 52.7Hz, so the large cabinet does not automatically deliver the deepest bass here. The native balance rises toward the treble, with some lower-midrange unevenness. DSP can improve that balance, but an EQ-optimized result is not its unadjusted performance.
