Short answer: the Buchardt A500. It ranks #12 of 31 powered bookshelf speakers by sound quality at $4150; the JBL 4329P ranks #18 and costs $4500, so there is not much of a tradeoff to weigh.
What the Buchardt A500 offers: A sophisticated three-way active system with 450W and DSP per cabinet, using the rear 6-inch driver as a cardioid/low-bass element rather than a passive radiator. Watch for: Passive sensitivity is not applicable and performance depends materially on the selected DSP master, so a single response specification cannot describe every setup.
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… Watch for: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.
Buy the Buchardt A500. It ranks higher for sound quality than the JBL 4329P and costs less, so there is no real case for the other one.

The Two Speakers In Full
Buchardt A500: $4,150/pair Buchardt Audio
Pros: A sophisticated three-way active system with 450W and DSP per cabinet, using the rear 6-inch driver as a cardioid/low-bass element rather than a passive radiator. Erin found neutral balance, excellent directivity matching through the shallow waveguide, strong imaging and surprisingly deep, clean bass for the enclosure size. Downloadable master tunings can trade extension, latency and maximum SPL, while the Platin hub adds WiSA wireless, room correction and streaming. Distortion remained unobtrusive even at levels Erin considered unnecessarily loud.
Cons: Passive sensitivity is not applicable and performance depends materially on the selected DSP master, so a single response specification cannot describe every setup. The standard tuning protects the small woofers with limiting at high bass output, and ultimate headroom cannot match a large tower or a subwoofer-assisted system. Hub dependence and app/software lifecycle add failure modes absent from passive speakers; analog input is converted to DSP, and the premium price buys an ecosystem as much as drivers and cabinet.

JBL 4329P: $4,500 Amazon
Pros: 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.
Cons: 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.
