Short answer: the Buchardt A500 for better sound quality, the JBL 4305P for the lower price. The Buchardt A500 ranks #12 of 31 powered bookshelf speakers at $4150. The JBL 4305P ranks #13 at $2200, $1950 cheaper.
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 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Watch for: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room, so this is a near/midfield system rather than a high-output theater…
Buy the Buchardt A500 if sound quality matters more than the price. Buy the JBL 4305P if the price matters more than sound quality.

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 4305P: $2,200/pair Amazon JBL
Pros: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Tonality is neutral and non-fatiguing, vocal coloration is absent, imaging is precise, and the HDI horn maintains near-constant horizontal directivity above 2kHz. Each speaker is bi-amplified (125W LF + 25W HF), while USB, optical, balanced analog, AirPlay 2, Chromecast, Bluetooth and 24/192 wired interconnect make this an unusually complete system. Grilles caused no meaningful response penalty.
Cons: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room, so this is a near/midfield system rather than a high-output theater speaker. A baffle discontinuity produces a 1–2kHz directivity mismatch that cannot be corrected uniformly in the vertical plane; stay within about +/-5° of tweeter height. Soundstage depth and layering trailed the KEF Reference 1 Meta, and wireless speaker linking caps resolution at 24/96.
