Short answer: the Neumann KH120 MKII for better sound quality, the Neumi BS5P for the lower price. The Neumann KH120 MKII ranks #2 of 64 powered bookshelf speakers at $2000. The Neumi BS5P ranks #60 at $150, $1850 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 Neumi BS5P offers: Exceptionally broad connectivity for the price: Bluetooth, optical, coaxial and RCA inputs, remote control and 75W total amplification. The 5-inch fiberglass woofer/1-inch silk-dome platform has generally useful directivity outside port resonances and therefore responds well to corrective EQ. Compact dimensions and ample nearfield volume make it practical for a desk or small room. Watch for: The original firmware Erin reviewed produces a pronounced V-curve—excess midbass and treble with recessed dialogue/midrange—and is a fidelity step backward from the passive BS5. Nearfield treble above 8kHz rises as much as 4dB relative to farfield, distortion is already substantial at 86dB, and compression becomes severe above 96dB. Port resonances further contaminate the response. Erin later measured improved firmware, but buyers must confirm revision. Passive sensitivity and impedance are not applicable.
Buy the Neumann KH120 MKII if sound quality matters more than the price. Buy the Neumi BS5P if the price matters more than sound quality.
If sound quality matters at all to you, skip the Neumi BS5P. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
