Short answer: the JBL 305P MKII on value, the Genelec 8320A on bass alignment. The 305P MKII is a fantastic value, extremely close to the Focal Alpha 50 EVO and almost indistinguishable, though its amps may hiss slightly at low levels and its rear port can be an issue close to walls. The 8320A’s listening window smoothness score of 0.53 and low frequency alignment Q of 0.227 give it the cleanest bass rolloff in this batch.
What the Genelec 8320A gets right: The Directivity Control Waveguide and die cast aluminum Minimum Diffraction Enclosure produce a listening window smoothness score of 0.53 and a low frequency alignment Q of just 0.227, the cleanest, least resonant bass rolloff of any speaker in this whole batch. Watch for: On axis deviation measures 0.169dB average, decent but not class leading next to the AsciLab and Audio Smile entries in this batch.
Buy the Genelec 8320A when sound quality outweighs the price for you, and the JBL 305P MKII when the price outweighs sound quality instead.

Genelec 8320A: $1,700 per pair B&H Photo Video eBay
Pros: A measured 1.6dB span from 300Hz to 5kHz and preference scores of 5.52 standalone and 8.04 with an ideal subwoofer support accurate close-range monitoring. The waveguide helps control the balance between direct and reflected sound. GLM room calibration is useful for matching levels and placement in a compact setup. Measured bass extension of 67.4Hz (-3dB).
Cons: The -3dB point is about 67Hz, making a subwoofer important for lower bass and giving the larger 8330A a practical advantage without one. Calibration hardware is sold separately. The small woofer limits its intended listening distance and bass output; a favorable response-fit parameter is not evidence that it has uniquely well-damped bass or unusually high headroom.

JBL 305P MKII: $289.00 per pair Amazon eBay
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.
