Short answer: the JBL 4305P for small-room bass; the Focal Alpha 65 EVO for soundstage. The Focal is very neutral and beats the Yamaha HS8 on soundstage and instrument definition, though it ignores sub-bass and its LF/HF trim dials lack a center detent. The 4305P reaches a 45Hz F3, but its limiter becomes conspicuous around 96dB.
What the JBL 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension (excellent for a compact 5.25-inch active monitor). Watch for: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room.
The case for the Focal Alpha 65 EVO: Very neutral, not quite as good as the Klasik 2020 in the midrange, but with better soundstage and instrument definition than the HS8. The tradeoff: Ignores sub-bass, and the LF/HF trim dials lack a center detent so getting back to flat takes trial and error.
Buy the JBL 4305P. It is rated higher for sound quality, and the $501.99 saving on the Focal Alpha 65 EVO is not enough to make up the difference.

The Two Speakers In Full
JBL 4305P: $1,499.99 per pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors. Measured bass extension of 45Hz (-3dB).
Cons: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle. Limiting becomes relevant at high output, particularly with bass-heavy music. It suits near- to midfield listening better than the largest high-output systems here. Erin measured about 8dB lost near 50Hz at the highest drive level and reached roughly 93dB unweighted at 2m in-room.

Focal Alpha 65 EVO: $998 per pair Amazon eBay
Pros: ASR measured 42.5Hz -3dB extension, providing useful low-end reach for music. Analog input options and tonal controls make it straightforward to integrate into a studio, with a 6.59 ideal-subwoofer score indicating respectable but not leading tonality. Measured bass extension of 45Hz (-3dB).
Cons: The measured 2.7dB response span from 300Hz to 5kHz and listening-window variation do not support a claim of reference-level neutrality. Placement and external correction may help. An anomalous distortion result from an individual sample should not be treated as a proven defect in every unit.
