Short answer: the Kali Audio IN-8 V2 if sound quality matters most, the JBL 306P MKII if price matters most. The Kali Audio IN-8 V2 ranks #38 of 113 powered bookshelf speakers, rated 4.4/5, at $998. The JBL 306P MKII ranks #67, rated 4.1/5, at $238, $760 cheaper.
The Kali Audio IN-8 V2 is the better-sounding choice. The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. It has an adjustable EQ, which the JBL 306P MKII lacks. The catch: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward.
What the JBL 306P MKII does well: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The tradeoff: The 3.4dB response span from 300Hz to 5kHz is less even than the 308P MKII’s, with midrange resonances affecting neutrality.
Buy the Kali Audio IN-8 V2 if sound quality matters more than the price. Buy the JBL 306P MKII if the price matters more than sound quality.

Kali Audio IN-8 V2: $998 per pair Amazon eBay
Same family: the Kali Audio IN-5 (smaller bookshelf, rated 4.2/5) and the Kali Audio IN-UNF (larger bookshelf, rated 3.3/5).
Pros: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Measured -3dB extension of 45.4Hz provides useful bass; boundary settings assist placement. The front port allows placement near a wall without port noise problems. Measured bass extension of 44Hz (-3dB), with a measured sensitivity of 89dB.
Cons: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward. Bass and limiter behavior constrain high-level playback. These measurements apply to the V2, not the first-generation IN-8. On-axis, the 4 to 5kHz range sounds forward; Kali recommends about 10° of toe-out, and some EQ helps.

JBL 306P MKII: $238 per pair B&H Photo Video eBay
Same family: the JBL 305P MKII (smaller bookshelf, rated 4.3/5) and the JBL 308P MKII (larger bookshelf, ranked higher, rated 4.4/5).
Pros: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The waveguide supports broad horizontal listening coverage, and basic boundary controls help with setup. Measured bass extension of 46.9Hz (-3dB).
Cons: The 3.4dB response span from 300Hz to 5kHz is less even than the 308P MKII’s, with midrange resonances affecting neutrality. Hiss can matter at a quiet desk, while bass distortion limits demanding playback. A subwoofer improves bandwidth but does not remove the midrange irregularities. A narrow dip around 1.6kHz shows in the on-axis and listening-window curves.
