Short answer: the Genelec 8351B takes the measurement win; the Kali Audio LP-6 V2 is the value pick. The 8351B’s spinorama is exceptionally flat on and off axis, though deep bass distortion rises at 96dB SPL/1m and suffers below about 100Hz. 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 and can expose crossover lobing.
Buy the Genelec 8351B if sound quality matters more than the price. Buy the Kali Audio LP-6 V2 if the price matters more than sound quality.

The Two Speakers In Full
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.

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.
