Edifier R2850DB vs Neumann KH420

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.

On the Edifier R2850DB side: 3 way speaker. Set against that: Quite large and heavy.

The case for the Neumann KH420: CEA2034 spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB at its one. The tradeoff: Horizontal beamwidth, while well controlled, is on the narrow side at about ±55 degrees.

Buy the Edifier R2850DB when the price outweighs sound quality for you, and the Neumann KH420 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.

Neumann KH420: $10500 per pair B&H Photo Video eBay

Pros: A 1.2dB response span from 300Hz to 5kHz, 7.51 ideal-subwoofer score and 27.8Hz measured -3dB extension combine accurate mids with genuinely deep bass. Its three-way design and low distortion at normal levels make it particularly attractive for larger listening distances and dynamic material. Measured bass extension of 32Hz (-3dB).

Cons: It is a large, heavy studio monitor rather than an easy desktop speaker. Vertical alignment matters around the crossover regions. Bass distortion rises as playback levels increase, and the measured high-level limits still apply despite the substantial drivers and amplifiers.
