Short answer: the JBL 4305P. It ranks #40 of 118 powered bookshelf speakers by sound quality, rated 4.4/5, at $1,499.99; the Genelec G Four ranks #67, rated 4.2/5, and costs $2,790, so there is not much of a tradeoff to weigh.
What the JBL 4305P does well: 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. It keeps a wired aux input, which the Genelec G Four lacks. The tradeoff: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.
The case for the Genelec G Four: A home speaker built on the drivers and waveguide of the Genelec 8040B studio monitor: a 6.5” woofer and 0.75” metal-dome tweeter in a die-cast aluminum cabinet, each with its own 90W amplifier. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Genelec 8040B it is based on.
Buy the JBL 4305P. It is rated higher for sound quality than the Genelec G Four and costs less, so only choose the other one for a particular feature it does better.
Worth knowing: the Genelec G Four has not been measured yet. Its rating is estimated from related models, with a likely range of 3.9 to 4.5, so treat this verdict as provisional.

The Two Speakers In Full
JBL 4305P: $1,499.99 per pair Amazon JBL eBay
Same family: the JBL 4329P (larger bookshelf, ranked lower, rated 4.1/5).
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.

Genelec G Four: $2,790 per pair Estimated B&H Photo Video eBay
Same family: the Genelec G One (smaller bookshelf, estimated 4.4/5), the Genelec G Two (smaller bookshelf, rated 4.3/5), the Genelec G Three (smaller bookshelf, estimated 4.5/5) and the Genelec G Five (larger bookshelf, ranked higher, estimated 4.3/5).
Pros: A home speaker built on the drivers and waveguide of the Genelec 8040B studio monitor: a 6.5” woofer and 0.75” metal-dome tweeter in a die-cast aluminum cabinet, each with its own 90W amplifier. Bass reaches 48Hz (±2.5dB) and 41Hz (-6dB), and it plays to 105dB short-term, enough to fill a medium living room without a subwoofer. RCA and balanced XLR inputs and rear tone switches handle consumer and pro sources and different placements.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Genelec 8040B it is based on. There is no GLM room calibration or digital input, and at nearly 10kg each it needs sturdy stands or shelves.
