Short answer: the JBL 4305P ranks #28 of 66 powered bookshelf speakers by sound quality at $2200; the Focal Twin6 Be ranks #60 at $2200. The price gap is small enough that the sound-quality ranking should decide it.
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, so this is a near/midfield system rather than a high-output theater…
What the Focal Twin6 Be offers: High-output 2.5-way studio monitor with an inverted beryllium tweeter and two 6.5-inch W-composite drivers, one covering bass/midrange and the other reinforcing only 40-150Hz. Watch for: The response and directivity are not as uniformly neutral as newer waveguided three-way monitors, and Erin suspected intermodulation-related roughness even though conventional harmonic distortion was low.
Buy the JBL 4305P. It ranks higher for sound quality than the Focal Twin6 Be at the same price, so there is no real case for the other one.
The Focal Twin6 Be is not a sound-quality pick. It sits near the bottom of the 66 powered bookshelf speakers; there are better options higher up.

JBL 4305P: $2,200/pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 6.54 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors.
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.

Focal Twin6 Be: $2,200 each Amazon eBay
Pros: The dual-woofer arrangement offers useful output capability for studio work, with a 48.3Hz measured -3dB point in the horizontal test. Its professional controls and format can suit a dedicated monitoring installation.
Cons: The horizontal measurement scores 5.33 with an ideal subwoofer and spans 2.9dB from 300Hz to 5kHz. Off-axis variation limits tonal consistency across listening positions. Orientation matters, and neither the beryllium tweeter nor the additional woofer makes its measured balance class-leading.
