Short answer: the Neumann KH120 MKII on measured sound quality, the M-Audio BX5 D3 on price. The Neumann KH120 MKII ranks #2 of 65 powered bookshelf speakers at $2000. The M-Audio BX5 D3 ranks #30 at $149.50, $1850.50 cheaper.
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 M-Audio BX5 D3 offers: The third-party measurements suggest scores of 3.34 standalone and 5.94 with an ideal subwoofer, with a 2.4dB midrange span. Balanced inputs and acoustic-space adjustment are useful for a basic studio setup. The measured -3dB estimate is about 64Hz. Watch for: The response slopes downward by about 0.65dB per octave, potentially softening treble relative to the midrange. There is no digital input or automatic calibration, and the preference estimate does not verify distortion or output headroom.
Buy the Neumann KH120 MKII if sound quality is the priority over the price, or the M-Audio BX5 D3 if the price is the priority over sound quality.
