Short answer: the JBL M2 Master Reference Monitor for better sound quality, the Adam Audio T8V for the lower price. The JBL M2 Master Reference Monitor ranks #56 of 113 powered bookshelf speakers, rated 4.3/5, at $15,000. The Adam Audio T8V ranks #92, rated 3.9/5, at $719.98, $14,280.02 cheaper.
What the Adam Audio T8V does well: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. Watch for: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives.
The JBL M2 Master Reference Monitor is the more accurate, deeper-bass choice. A high-output specialist: Erin’s low-distortion and compression tests support considerable dynamic capability, beyond what a single preference score captures. Its measured preference score, a predictor of how neutral it sounds, is 5.74 against 4.65 for the Adam Audio T8V. Its bass reaches about 34Hz before falling 3dB, against 39.6Hz for the Adam Audio T8V. 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 T8V when the price outweighs sound quality for you, and the JBL M2 Master Reference Monitor when sound quality outweighs the price instead.

Adam Audio T8V: $719.98 per pair Amazon eBay
Same family: the Adam Audio T5V (smaller bookshelf, rated 4/5) and the Adam Audio T7V (smaller bookshelf, ranked lower, rated 3.9/5).
Pros: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. Analog inputs and basic shelf controls offer uncomplicated studio integration. Measured bass extension of 39.6Hz (-3dB).
Cons: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives. Treble emphasis and crossover-region vertical cancellation make listening height important. Deep bass and an AMT tweeter do not by themselves imply accurate sound. A notch around 4.6kHz, where tweeter and woofer interact, and a hole below the tweeter axis mean the tweeter should sit at or above ear height.

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.
