Short answer: the Buchardt A500. It ranks #15 of 66 powered bookshelf speakers by sound quality at $4150; the JBL 4329P ranks #44 and costs $4500, so there is little reason to consider the other one.
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, which settles it without a real tradeoff to make.

The Two Speakers In Full
Buchardt A500: $4,150/pair Buchardt Audio eBay
Pros: Erin measured unusually deep bass for the cabinet size: 24.9Hz at -3dB. A 1.8dB response span from 300Hz to 5kHz and 6.12 standalone preference score support balanced, full-range listening. Master Tunings and optional wireless integration provide practical flexibility.
Cons: Bass extension depends on the selected tuning and comes with output tradeoffs at high levels. The 7.01 ideal-subwoofer score is good but not class-leading. A rear-facing woofer does not by itself establish cardioid radiation, and alternate Master Tunings should not inherit the measured configuration’s score.

JBL 4329P: $4,500 Amazon eBay
Pros: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Integrated amplification and streaming make it convenient for a full-range living-room system, and its larger format is useful when scale matters.
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 5.83 ideal-subwoofer score trails the 4305P. There is no HDMI connection for the simplest TV hookup.
