Short answer: the Neumann KH420 for measured accuracy, the Edifier R2850DB only as a budget three-way. The KH420’s spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB, though its well-controlled horizontal beamwidth is narrow at about ±55 degrees. The R2850DB is a three-way, but it is quite large and heavy.
Buy the Edifier R2850DB when the price outweighs sound quality for you, and the Neumann KH420 when sound quality outweighs the price instead.
