Short answer: the Neumann KH420. It ranks #5 of 66 powered bookshelf speakers by sound quality at $10500; the Dutch & Dutch 8C ranks #9 and costs $13000, so there is little reason to consider the other one.
On the Dutch & Dutch 8C side: All-in-one powered design with 1-inch dome tweeter, 8-inch midrange, and dual 8-inch rear subwoofers. Set against that: Premium pricing reflects integrated amplification and DSP cardioid processing.
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 Neumann KH420. It ranks higher for sound quality than the Dutch & Dutch 8C and costs less, so there is no real case for the other one.

The Two Speakers In Full
Dutch & Dutch 8C: $13000 Tidepoolaudio eBay
Pros: Very deep measured bass reaches 23.4Hz at -3dB, while the 1.8dB response span from 300Hz to 5kHz supports even mids. The 6.51 standalone score reflects that full-range strength. Cardioid midrange radiation and boundary-aware bass adjustment help integrate the system with nearby walls.
Cons: Cardioid operation reduces some reflections; it does not make the speaker independent of the room. Rear-woofer placement and setup remain important. Its 7.16 ideal-subwoofer score trails the strongest tonal performers here, although its deep native bass is a meaningful advantage for listening without a sub.

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.
