Short answer: the Dutch & Dutch 8C for better sound quality, the JBL 4329P for the lower price. The Dutch & Dutch 8C ranks #3 of 61 powered bookshelf speakers at $13000. The JBL 4329P ranks #21 at $4500, $8500 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 Dutch & Dutch 8C offers: All-in-one powered design with 1-inch dome tweeter, 8-inch midrange, and dual 8-inch rear subwoofers. Cardioid design achieves forward-firing response from 100 Hz upward, eliminating rear-wall boundary reflections that typically muddy imaging and soundstage. Measures nearly flat response (plus/minus 1.5 dB from 25 Hz to 18 kHz) across the full range. Achieved 105 dB listening levels without audible distortion or woofer bottoming, providing exceptional dynamic headroom. Neutral, accurate tonal balance with surprisingly spacious soundstage depth. Watch for: Premium pricing reflects integrated amplification and DSP cardioid processing. Limited to powered amplification; not suitable for passive systems. Relatively fixed setup - bass response heavily dependent on wall placement and room modes.
