Short answer: the Neumann KH 310 A on measured accuracy, the Kali Audio LP-6 V2 on value. The KH 310 A’s CEA2034 spinorama shows a near-perfect on-axis response with superb directivity control and minimal off-axis variation, though an unidentified dip around 80Hz remains. The LP-6 V2 is outstandingly neutral for the money with no audible amplifier hiss, but a vertical directivity disturbance around 1.5-2kHz makes ear height important.
Buy the Neumann KH 310 A if sound quality is the priority over the price, or the Kali Audio LP-6 V2 if the price is the priority over sound quality.

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.

Kali Audio LP-6 V2: $398 per pair Amazon B&H Photo Video eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5).
Pros: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. The waveguide and placement switches help with practical setup, and the second generation improves close-range noise behavior. Measured bass extension of 42Hz (-3dB).
Cons: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness. Vertical crossover behavior makes ear-height placement important, and compression limits loud bass playback. Its good tonal score is not evidence of the output capability of a much larger monitor.
