Short answer: the JBL M2 Master Reference Monitor. It ranks #1 of 31 powered bookshelf speakers by sound quality; the Dutch & Dutch 8C ranks #3.
What the JBL M2 Master Reference Monitor offers: Flagship quasi-active two-way with a 15-inch 2216Nd woofer and D2 compression driver crossing near 800Hz through a large Image Control Waveguide. Watch for: The required bi-amplification/DSP ecosystem is expensive and complex; Erin’s Crown I-Tech 5000HD had fans loud enough that he moved it to another room for measurements.
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. Watch for: Premium pricing reflects integrated amplification and DSP cardioid processing.
Buy the JBL M2 Master Reference Monitor if sound quality matters more than the price. Buy the Dutch & Dutch 8C if the price matters more than sound quality.

JBL M2 Master Reference Monitor: Contact dealer JBL Professional Dealer Locator
Pros: Flagship quasi-active two-way with a 15-inch 2216Nd woofer and D2 compression driver crossing near 800Hz through a large Image Control Waveguide. Erin measured F3 at 34Hz, less than 1% THD at 86 and 96dB, and only about 0.25dB compression by 102dB. Radiation stays broadly constant to roughly +/-60 degrees through 8-9kHz, producing excellent direct/reflected-sound agreement and enormous clean dynamic range. External DSP amplification permits precise factory crossover, phase and response correction.
Cons: The required bi-amplification/DSP ecosystem is expensive and complex; Erin’s Crown I-Tech 5000HD had fans loud enough that he moved it to another room for measurements. Midrange resonances remain visible despite the otherwise neutral response, and treble dispersion narrows above roughly 9kHz before beaming above 12kHz. Each 130-pound enclosure is physically imposing. This is an amplified system, so passive impedance and sensitivity figures are not applicable to the complete configured product.

Dutch & Dutch 8C: $13000 Tidepoolaudio
Pros: 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.
Cons: 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.
