Short answer: the JBL 4305P. It ranks #28 of 68 powered bookshelf speakers by sound quality, rated 4.4/5, at $1,499.99; the JBL 4329P ranks #45, rated 4.1/5, and costs $4,500, so there is little reason to consider the other one.
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. Watch for: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.
The case for the JBL 4329P: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. The tradeoff: The measured 4.5dB response span from 300Hz to 5kHz includes a notable midrange dip, so it is not as neutral as its size and price might suggest.
Worth knowing: the JBL 4329P has been discontinued and is hard to find new at this point.
Buy the JBL 4305P. It is rated higher for sound quality than the JBL 4329P and costs less, so only choose the other one for a particular feature it does better.

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.

JBL 4329P: $4,500 per pair Discontinued eBay
Pros: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Integrated amplification and streaming make it convenient for a full-range living-room system, and its larger format is useful when scale matters. Measured bass extension of 31Hz (-3dB), with a measured sensitivity of 102.2dB.
Cons: The measured 4.5dB response span from 300Hz to 5kHz includes a notable midrange dip, so it is not as neutral as its size and price might suggest. Its 6.72 ideal-subwoofer score trails the 4305P. There is no HDMI connection for the simplest TV hookup. Discontinued.
