Short answer: the Presonus Eris Studio 8, if you are buying new. The JBL 4329P ranks higher than it (#71 vs #97 of 113 powered bookshelf speakers, 4.1/5 vs 3.9/5) but is discontinued, so only consider it used; the Presonus Eris Studio 8 is still sold new at $419.98.
The case for the JBL 4329P: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller JBL 4305P. It keeps a wired aux input, which the Presonus Eris Studio 8 lacks. 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.
What the Presonus Eris Studio 8 does well: An 8-inch active monitor with XLR, TRS and RCA inputs and room-adjustment controls, providing flexible analog integration. The catch: The large cabinet requires substantial desk or stand space.
Buy the Presonus Eris Studio 8 if you want one new; the JBL 4329P is discontinued, so only look for it used.

JBL 4329P: $4,500 per pair Discontinued eBay
Pros: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller JBL 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 JBL 4305P. There is no HDMI connection for the simplest TV hookup. Discontinued.

Presonus Eris Studio 8: $419.98 per pair Amazon eBay
Older model: the PreSonus Eris E8 XT (ranked lower, estimated 3.7/5).
Same family: the PreSonus Eris Studio 4 (smaller bookshelf, estimated 3.4/5) and the PreSonus Eris Studio 5 (smaller bookshelf, estimated 3.6/5).
Pros: An 8-inch active monitor with XLR, TRS and RCA inputs and room-adjustment controls, providing flexible analog integration. Its cabinet and connection options suit a conventional studio setup.
Cons: The large cabinet requires substantial desk or stand space. Analog room-adjustment controls offer less flexibility than automatic calibration or parametric correction.
