Short answer: the JBL M2 Master Reference Monitor. It ranks #1 of 66 powered bookshelf speakers by sound quality; the Adam Audio T8V ranks #28.
What the Adam Audio T8V offers: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8 Watch for: A crossover-region notch around 4.6kHz where tweeter and woofer interact, and a hole in the vertical response below the tweeter axis - keep the tweeter at or above ear height. Distortion is well controlled at 86dB SPL but gets messier at 96dB.
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. 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. 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. 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.
