Neumann KH120 MKII vs Adam Audio A4V

Last updated: September 16, 2026

Short answer: the Neumann KH120 MKII for better sound quality, the Adam Audio A4V for the lower price. The Neumann KH120 MKII ranks #2 of 65 powered bookshelf speakers at $2000. The Adam Audio A4V ranks #42 at $599.99, $1400.01 cheaper.

Neumann KH120 MKII vs Adam Audio A4V

What the Neumann KH120 MKII offers: ASR’s Klippel data shows exceptional neutrality: only a 1.5dB span from 300Hz to 5kHz and low listening-window narrow-band deviation of 0.208. Scores of 5.75 standalone and 7.70 with an ideal subwoofer place it among the strongest measured options here. Bass reaches -3dB around 45Hz. The review reports very low distortion at 86dB/1m and clean performance outside deep bass at 96dB. Watch for: Vertical crossover interference makes listening height important even though horizontal dispersion is well controlled. A small directivity irregularity remains around 2kHz. Distortion increases below about 50Hz at high output; a subwoofer can extend the system and reduce low-frequency demands. High price, and a flat anechoic response still needs suitable placement in the room.

What the Adam Audio A4V offers: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.02 standalone and 5.43 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed. Watch for: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547. The native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.

Buy the Neumann KH120 MKII when sound quality outweighs the price for you, and the Adam Audio A4V when the price outweighs sound quality instead.
