Short answer: the JBL M2 Master Reference Monitor if sound quality matters most, the Adam Audio T7V if price matters most. The JBL M2 Master Reference Monitor ranks #34 of 66 powered bookshelf speakers at $15000. The Adam Audio T7V ranks #53 at $289.99, $14710.01 cheaper.
What the Adam Audio T7V offers: Spinorama’s digitized Audioholics data shows a fairly controlled 2.4dB frequency-deviation band from 300Hz to 5kHz, with only 0.7dB reference-band variation. The response above 200Hz is broadly balanced and the supplied correction filters require relatively modest adjustments, consistent with a monitor that responds well to EQ. Watch for: The available Spinorama record is a low-quality scanned graph truncated below 200Hz, so no preference score or trustworthy bass-extension score can be calculated. Vertical dispersion is narrow and listening height matters; the incomplete data does not justify the previous 4.3 rating, so an uncertainty adjustment is applied.
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.
Buy the Adam Audio T7V when the price outweighs sound quality for you, and the JBL M2 Master Reference Monitor when sound quality outweighs the price instead.
If sound quality matters at all to you, skip the Adam Audio T7V. It ranks near the bottom of the 66 powered bookshelf speakers, so look higher up the list instead.

Adam Audio T7V: $289.99 Amazon eBay
Pros: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Basic tonal controls and analog connections suit a straightforward nearfield system.
Cons: Correct listening height is important for the two-way crossover. Basic shelf controls offer less adjustment flexibility than parametric room correction.

JBL M2 Master Reference Monitor: $15,000/pair JBL Professional Dealer Locator eBay
Pros: A high-output specialist: Erin’s low-distortion and compression tests support considerable dynamic capability, beyond what a single preference score captures. Measured -3dB extension is 33.7Hz. The large woofer and waveguide are particularly useful for greater listening distances.
Cons: Its 4.1dB response span from 300Hz to 5kHz and 5.67 ideal-subwoofer score do not support a top tonal-accuracy ranking. It requires the correct external amplification and DSP rather than a simple built-in amplifier. The very large cabinet, installation cost and possible amplifier fan noise make it impractical for most desks.
