Short answer: the Neumann KH420 for better sound quality, the Kali Audio IN-8 V2 for the lower price. The Neumann KH420 ranks #5 of 66 powered bookshelf speakers at $10500. The Kali Audio IN-8 V2 ranks #26 at $499, $10001 cheaper.
The case for the Kali Audio IN-8 V2: Three-way coaxial (coincident) driver in a front-ported cabinet, allowing near-wall placement without port noise issues. The catch: Notable forwardness/brashness in the 4-5kHz range when listened to on-axis.
What the Neumann KH420 gets right: CEA2034 spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB at its one. The catch: Horizontal beamwidth, while well controlled, is on the narrow side at about ±55 degrees.
Buy the Kali Audio IN-8 V2 if the price is the priority over sound quality, or the Neumann KH420 if sound quality is the priority over the price.

Kali Audio IN-8 V2: $499.00 Amazon eBay
Pros: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 6.54 ideal-subwoofer score. Measured -3dB extension of 45.4Hz provides useful bass; boundary settings assist placement.
Cons: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward. Bass and limiter behavior constrain high-level playback. These measurements apply to the V2, not the first-generation IN-8.

Neumann KH420: $10500 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.
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.
