Short answer: the Genelec 8351B has been measured and ranked; the Genelec 8350A has not been measured in a way we can rank yet, so until it is, this comes down to features and price.
What the Genelec 8350A offers: An 8” woofer and 1” metal dome tweeter behind Genelec’s Directivity Control Waveguide, specified at ±1.5dB from 38Hz to 20kHz and down to 33Hz at -6dB, deep enough for most music without a subwoofer.
On the Genelec 8351B side: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB.
Price: the Genelec 8350A lists at $5,550 and the Genelec 8351B at $9,150.
Buy the Genelec 8351B if you want a speaker whose sound quality has been measured and ranked.
Buy the Genelec 8350A if you prefer its design or features, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
Genelec 8350A: $5,550 per pair B&H Photo Video eBay
Older model: the Genelec 8050B (rated 4.4/5).
Pros: An 8” woofer and 1” metal dome tweeter behind Genelec’s Directivity Control Waveguide, specified at ±1.5dB from 38Hz to 20kHz and down to 33Hz at -6dB, deep enough for most music without a subwoofer. GLM software measures your room and sets level, delay and EQ for each speaker automatically. 350W of amplification per speaker gives 112dB short-term output, with analog XLR and AES/EBU digital inputs.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. At 12.8kg and 452mm tall it needs solid stands, GLM calibration needs the separately sold GLM kit, and there is no RCA input for consumer gear.

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.
