Genelec 8351B vs Neumann KH 310 A

Short answer: the Genelec 8351B for off-axis consistency, the Neumann KH 310 A for a near-perfect on-axis response. The 8351B’s spinorama is exceptionally flat on and off axis, though its deep bass distorts at 96dB SPL/1m and suffers below about 100Hz. The KH 310 A shows superb directivity control and minimal off-axis variation, but an unidentified dip around 80Hz appears in the measurements.

Buy the Genelec 8351B. It is rated higher for sound quality, and the $4,152 saving on the Neumann KH 310 A is not enough to make up the difference.

Genelec 8351B: $9150 per pair B&H Photo Video eBay

Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).

Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.

Neumann KH 310 A: $4,998 per pair B&H Photo Video eBay

Pros: The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. Its 2.2dB response span from 300Hz to 5kHz and 7.70 ideal-subwoofer score support balanced monitoring with useful full-range capability. Measured bass extension of 35.2Hz (-3dB).

Cons: Its measured tonal balance is not as even as the KH 150 or the best coaxial alternatives. Correct orientation and listening height matter for the separated drivers. The analog system lacks the integrated calibration workflow of newer DSP models, so room correction requires additional equipment. An unexplained dip around 80Hz shows in the measurements.
