Genelec 8040B vs Neumann KH 310 A

Short answer: the Neumann KH 310 A on measured accuracy, with one open question. Its CEA2034 spinorama shows a near-perfect on-axis response with superb directivity control and minimal off-axis variation, though an unidentified dip around 80Hz shows up in the measurements and Neumann was asked to investigate. The Genelec 8040B is very expensive.

What the Genelec 8040B gets right: Based on the smaller sibling’s measured performance against others, it is ranked accordingly. The catch: Very expensive.

Buy the Neumann KH 310 A. It is rated higher for sound quality, and the Genelec 8040B is discontinued, so it is only available used.

Genelec 8040B: $2,790 per pair Discontinued B&H Photo Video eBay

Newer model: the Genelec 8340A. It’s likely to perform similarly, though we don’t have measurements to confirm that yet. It uses the same cabinet and woofer size, adding GLM room calibration and an AES/EBU digital input.

Pros: A compact professional monitor with balanced XLR input and analog room-adjustment controls. The manufacturer’s 41Hz limit is specified at -6dB, offering a useful reference for system planning without confusing it with a measured -3dB point.

Cons: It lacks GLM calibration and consumer streaming inputs. The balanced XLR connection may require an interface or controller for a typical desktop source. It is expensive. Discontinued.

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.
