Short answer: the JBL 4305P for a compact active monitor; the Focal Solo6 ST6 for a low-distortion driver set. The Focal’s beryllium inverted-dome tweeter over a 6.5-inch W composite cone is a rare combination, though its bass alignment Q is on the higher side and can add fullness. The 4305P reaches a 45Hz F3 with solid 40 to 50Hz in-room extension.
On the JBL 4305P side: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension (excellent for a compact 5.25-inch active monitor). The tradeoff: 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 speaker.
What the Focal Solo6 ST6 offers: Beryllium inverted-dome tweeter over a 6.5” ‘W’ composite sandwich-cone woofer - a low-mass, low-distortion driver combination rarely found below far pricier monitors. Watch for: Bass alignment Q is on the higher side, which can correlate with a touch of extra bass fullness/looseness versus a more critically-damped alignment.
Buy the JBL 4305P. It is rated higher for sound quality than the Focal Solo6 ST6 and costs less, which makes it the one to get unless you need something the other one does better.

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 Solo6 ST6: $2,998 per pair B&H Photo Video eBay
Pros: ASR measured a tight 1.6dB response span from 300Hz to 5kHz and a 7.34 ideal-subwoofer score, supporting accurate midrange monitoring. The beryllium tweeter and Focus mode offer a useful professional workflow, with Focus serving as an alternate mix-check presentation. Its beryllium inverted-dome tweeter and 6.5-inch W composite sandwich-cone woofer are a low-mass, low-distortion pairing. Measured bass extension of 46.9Hz (-3dB).
Cons: The measured -3dB point is 46.9Hz, so deep-bass work benefits from a subwoofer. The standard-mode score does not apply to Focus mode. There is no automatic room-calibration system, and premium driver materials alone do not establish superior sound.
