Neumann KH120 MKII vs Dayton Audio M4

Last updated: August 25, 2026

Short answer: the Neumann KH120 MKII for better sound quality, the Dayton Audio M4 for the lower price. The Neumann KH120 MKII ranks #2 of 64 powered bookshelf speakers at $2000. The Dayton Audio M4 ranks #28 at $249.98, $1750.02 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 Dayton Audio M4 offers: Good build quality. Has a subwoofer output for extending the low end. Overall linearity is decent for the price. Avoids sibilance since it’s slightly recessed right in the harsh 4-8kHz region. Watch for: The amplifier is only in the left speaker, so it’s not separate amps in each unit. Bass doesn’t extend very deep, and unlike some rivals it doesn’t use DSP to boost the low end. Sounds noticeably different up close versus at a normal listening distance, with a softer treble near field and a more recessed upper midrange farther away. Limited output headroom - distortion rises sharply above about 93dB, so it’s better suited to near-field or desktop use than as a far-field living-room speaker.

Buy the Neumann KH120 MKII if sound quality matters more than the price. Buy the Dayton Audio M4 if the price matters more than sound quality.
