Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL 4329P is the better pick: it ranks #71 of 113 powered bookshelf speakers by sound quality (rated 4.1/5), against #77 (rated 4.0/5) for the Emotiva Airmotiv 6s. If you want one new, the Neumann KH 150 ranks #8 at $3,398.
The JBL 4329P is the deeper-bass option. Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Its bass reaches about 31Hz before falling 3dB, against 49.1Hz for the Emotiva Airmotiv 6s. It keeps a wired aux input, which the Emotiva Airmotiv 6s lacks. 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 Emotiva Airmotiv 6s: ASR measured 49.1Hz -3dB bass extension and a 5.75 ideal-subwoofer score. Watch for: The 3.0dB response span from 300Hz to 5kHz includes lower-midrange unevenness that can change vocal weight.
Buy the JBL 4329P only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Neumann KH 150 instead.

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.

Emotiva Airmotiv 6s: $800 per pair Discontinued eBay
Pros: ASR measured 49.1Hz -3dB bass extension and a 5.75 ideal-subwoofer score. The review found useful output capability, making it a credible option for ordinary nearfield playback with additional bass support when needed. Measured bass extension of 49.1Hz (-3dB).
Cons: The 3.0dB response span from 300Hz to 5kHz includes lower-midrange unevenness that can change vocal weight. Treble peaks also prevent a fully neutral balance. Equalization may help, but the substantially higher EQ-optimized score is not its native performance. A suckout between 300 and 600Hz in the listening window is followed by a peak from 600Hz up. Discontinued.
