Short answer: the JBL 4329P for better sound quality, the KRK Rokit 8 G4 for the lower price. The JBL 4329P ranks #21 of 66 powered bookshelf speakers at $4500. The KRK Rokit 8 G4 ranks #46 at $500, $4000 cheaper.
What the JBL 4329P offers: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement, with strong bass authority rather than a rolled-off, thin low end. Wide, constant horizontal directivity through the midrange and into the treble (about ±60°, wider than most horn-loaded designs which tend to run closer to ±40°) gives a wide, stable stereo image without needing to toe the speakers out and lose top-end energy. The reviewer listened for an hour-long sessions repeatedly without listener fatigue, across two very different rooms, with consistently great results in both. Extensive connectivity: USB, Optical, Bluetooth, analog, 3.5mm, AirPlay 2, and 24-bit/192kHz support; comes with a remote. Watch for: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC. The supplied ethernet link cable between the two speakers is short - workable at close range but not long enough for wider speaker placement, so budget for a longer aftermarket cable if your setup needs it. A dip around 900Hz shows up in the on-axis measurement that the reviewer couldn’t fully explain (ruled out the ports as the cause, suspects cabinet edge diffraction), though it wasn’t something that bothered him in listening. At $4,500/pair, this is a serious investment for a bookshelf-format speaker.
What the KRK Rokit 8 G4 offers: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8 Watch for: No detailed measurement caveats are currently recorded.
Buy the JBL 4329P if sound quality matters more than the price. Buy the KRK Rokit 8 G4 if the price matters more than sound quality.
