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 #95 (rated 3.9/5) for the KRK Rokit 8 G4. If you want one new, the KRK Rokit 8 G5 replaces the KRK Rokit 8 G4 and is rated 4.0/5 at $1,276.
What the JBL 4329P does well: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller JBL 4305P. It keeps a wired aux input, which the KRK Rokit 8 G4 lacks. 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.
Why pick the KRK Rokit 8 G4: An 8-inch active monitor with balanced studio connections and room-adjustment controls, offering a practical basis for a desktop or small studio system. Watch for: The large cabinet requires substantial desk or stand space.
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, buy the KRK Rokit 8 G5, which replaces the KRK Rokit 8 G4.

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 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.

KRK Rokit 8 G4: $500 per pair Discontinued Amazon eBay
Newer model: the KRK Rokit 8 G5, ranked higher, estimated 4/5.
Same family: the KRK Rokit 5 G4 (smaller bookshelf, rated 3.7/5) and the KRK Rokit 7 G4 (smaller bookshelf, ranked lower, rated 3.9/5).
Pros: An 8-inch active monitor with balanced studio connections and room-adjustment controls, offering a practical basis for a desktop or small studio system. The larger format may suit listeners who want more scale than a compact monitor.
Cons: The large cabinet requires substantial desk or stand space. Its balanced studio inputs need a suitable source connection rather than offering built-in consumer streaming. Discontinued.
