Short answer: the Focal Twin6 Be, if you are buying new. The JBL 4329P ranks higher than it (#45 vs #62 of 68 powered bookshelf speakers, 4.1/5 vs 3.8/5) but is discontinued, so only consider it used; the Focal Twin6 Be is still sold new at $4,400.
The case for the JBL 4329P: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Watch for: 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.
Why pick the Focal Twin6 Be: The dual-woofer arrangement offers useful output capability for studio work, with a 48.3Hz measured -3dB point in the horizontal test. Watch for: The horizontal measurement scores 6.06 with an ideal subwoofer and spans 2.9dB from 300Hz to 5kHz.
Buy the Focal Twin6 Be new; the JBL 4329P is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
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.

Focal Twin6 Be: $4,400 per pair 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. Measured bass extension of 48.3Hz (-3dB).
Cons: The horizontal measurement scores 6.06 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. Erin suspected intermodulation-related roughness even though harmonic distortion measured low.
