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 #56 of 113 powered bookshelf speakers, rated 4.3/5, at $15,000. The Adam Audio T7V ranks #93, rated 3.9/5, at $579.98, $14,420.02 cheaper.
What the Adam Audio T7V does well: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Watch for: Correct listening height is important for the two-way crossover.
The JBL M2 Master Reference Monitor is the better-sounding, deeper-bass option. A high-output specialist: Erin’s low-distortion and compression tests support considerable dynamic capability, beyond what a single preference score captures. Its bass reaches about 34Hz before falling 3dB, against 65Hz for the Adam Audio T7V. The catch: Its 4.1dB response span from 300Hz to 5kHz and 6.58 ideal-subwoofer score do not support a top tonal-accuracy ranking.
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.

Adam Audio T7V: $579.98 per pair Amazon eBay
Same family: the Adam Audio T5V (smaller bookshelf, rated 4/5) and the Adam Audio T8V (larger bookshelf, ranked higher, rated 3.9/5).
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. Measured bass extension of 65Hz (-3dB).
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 per 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. Measured bass extension of 34Hz (-3dB).
Cons: Its 4.1dB response span from 300Hz to 5kHz and 6.58 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.
