Short answer: the Fluid Audio Image 2. Both are rated 4.1/5 for sound quality (#43 and #45 of 68 powered bookshelf speakers), and the Fluid Audio Image 2 costs $1899 against $4500 for the JBL 4329P, with sound quality a draw, the lower price decides it.
What the Fluid Audio Image 2 does well: Measured -3dB extension of 38.1Hz gives useful bass reach, while a 2.5dB response span from 300Hz to 5kHz supports broadly balanced mids. The tradeoff: The 6.80 ideal-subwoofer score places its measured native tonality below the leading monitors.
The case for the JBL 4329P: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. The catch: 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.
Buy the Fluid Audio Image 2. Both are rated the same for sound quality, and it costs $2601 less than the JBL 4329P.

Fluid Audio Image 2: $3,798 per pair Fluid Audio eBay
Pros: Measured -3dB extension of 38.1Hz gives useful bass reach, while a 2.5dB response span from 300Hz to 5kHz supports broadly balanced mids. The active multiway design and DSP tools offer flexibility for a studio installation.
Cons: The 6.80 ideal-subwoofer score places its measured native tonality below the leading monitors. DSP flexibility should not be confused with verified accuracy before adjustment. Full-range headroom, room integration and cabinet placement still need attention in a demanding monitoring system.

JBL 4329P: $4,500 per pair Amazon 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.
