Short answer: the Buchardt A10. It ranks #11 of 68 powered bookshelf speakers by sound quality, rated 4.7/5, at $4,300; 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 Buchardt A10 does well: The measured tuning combines 31.5Hz -3dB bass extension with preference scores of 7.28 standalone and 8.00 with an ideal subwoofer. The catch: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms.
Why pick 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 Buchardt A10. 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
Buchardt A10: $4300 per pair Buchardt Audio eBay
Pros: The measured tuning combines 31.5Hz -3dB bass extension with preference scores of 7.28 standalone and 8.00 with an ideal subwoofer. A 1.9dB response span from 300Hz to 5kHz supports broadly even mids, and selectable DSP tunings offer useful flexibility. Measured bass extension of 30Hz (-3dB).
Cons: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms. Deep-bass demands cause compression before the largest monitors reach their limits. A subwoofer with appropriate high-pass filtering can improve headroom; alternate presets should not be assumed to share the quoted scores.

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.
