Short answer: the Neumann KH120 MKII for better sound quality, the Airpulse A100 for the lower price. The Neumann KH120 MKII ranks #2 of 64 powered bookshelf speakers at $2000. The Airpulse A100 ranks #17 at $999.99, $1000.01 cheaper.
What the Neumann KH120 MKII offers: CEA2034 spinorama is about as flat as the reviewer has measured, with excellent directivity aside from a small blip around 2kHz, and bass response that stays flat almost down to 50Hz. Predicted in-room response is superb despite not being strictly valid for a near-field monitor at this distance. Horizontal beamwidth of about ±50 degrees is nice and well controlled. Distortion at 86dB SPL/1m is exceptionally low. Even at 96dB SPL/1m - just 1dB before the clipping indicator engages - it stays very clean outside of deep bass. Watch for: A minor directivity blip appears around 2kHz. Vertical directivity narrows quickly above the reference axis, so the reviewer recommends staying right at it. Distortion rises substantially in the deep bass under 50Hz at higher output (96dB SPL/1m). Cumulative spectral decay (waterfall) shows a resonance in the upper midrange. High price.
What the Airpulse A100 offers: Horn-loaded ribbon tweeter (inherited from Airpulse’s flagship 7001 monitor, designed by Phil Jones) paired with a 5” hard-anodized aluminum cone woofer - a distinctive, low-mass driver combination rarely seen below $1,000. Directivity spread is the widest and most controlled of this batch (directivity_spdi_stddev 4.26). A full input set for a desktop system: RCA, USB, optical, coaxial, and Bluetooth, plus a dedicated subwoofer output and an included IR remote. Watch for: On-axis deviation (aad_on_axis 0.498) trails the pricier options in this group, and there’s no app-based EQ or DSP - bass/treble trim is limited to physical rear-panel knobs not reachable from the remote. The compact 5” woofer caps sub-bass extension at 63.0Hz (-3dB) / 53.2Hz (-10dB), the second-shallowest in this batch, effectively expecting an external subwoofer for full-range use. No Wi-Fi streaming (AirPlay/Chromecast) - Bluetooth only.
Buy the Neumann KH120 MKII if sound quality matters more than the price. Buy the Airpulse A100 if the price matters more than sound quality.
