Short answer: the Kali Audio LP-6 V2. It ranks #37 of 113 powered bookshelf speakers by sound quality, rated 4.4/5, at $498; the JBL M2 Master Reference Monitor ranks #56, rated 4.3/5, and costs $15,000, which makes this an easy call rather than a real tradeoff.
What the Kali Audio LP-6 V2 does well: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. Watch for: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.
The JBL M2 Master Reference Monitor is the deeper-bass pick. 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 42Hz for the Kali Audio LP-6 V2. Watch for: 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 Kali Audio LP-6 V2. It is rated higher for sound quality than the JBL M2 Master Reference Monitor and costs less, so only choose the other one for a particular feature it does better.

Kali Audio LP-6 V2: $498 per pair B&H Photo Video eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5).
Same family: the Kali Audio LP-8 V2 (larger bookshelf, ranked lower, rated 4.1/5) and the Kali LP-UNF (larger bookshelf, rated 3.9/5).
Pros: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. The waveguide and placement switches help with practical setup, and the second generation improves close-range noise behavior. Measured bass extension of 42Hz (-3dB).
Cons: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness. Vertical crossover behavior makes ear-height placement important, and compression limits loud bass playback. Its good tonal score is not evidence of the output capability of a much larger monitor.

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.
